Opis:: Fossil fuel resources are decreasing daily while biodiesel fuels are attracting increasing attention worldwide as blending components or direct replacements for diesel fuel in vehicle engines. In this experiment the seed oils of 30 Neem (Azadirachta indica. A. juss) biotypes were screened and evaluated for their physio-chemical parameters for oil content, biodiesel yield, density, viscosity, iodine value , free fatty acid and saponification value. Hence the neem seed oil tested in this current study could be the potential sources of raw material for biodiesel production.

Opis:: Production of alternative energy sources from eco-friendly raw materials is supposed to be the most challenging job among researchers and academicians in the present world. Biodiesel has been considered as most useful green energy sources which is produced from Crude Neem (Azadirachta indica) oil (CNO) in the present study. The main advantages of CNO is that it is non-edible and is obtained abundantly in nature from neem seed. Initially, after bleaching of CNO, it is transesterified with methanol in the presence of non-specific enzyme catalyst Novozyme 40013 (Candida antarctica) maintaining certain reaction conditions. The parameters of the transesterification reaction have been identified as 8:1 molar ratio of methanol to CNO, 60 °C temperature in the presence of 6% enzyme Novozyme 40013 and 600 rpm of mixing intensity for 9 hrs of reaction duration. The product obtained, after completion of reaction, has been estimated of 91.24% biodiesel along with minor amounts of triacylglycerol (TAG), diacylglycerol (DAG) and monoacylglycerol (MAG). Finally, the physico-chemical properties of CNO biodiesel have been analysed and it showed good conformity with diesel fuel and biodiesel standard.

Opis:: Neem has immense biocontrol potential against a large number of pathogens causing various diseases in human beings and plants. The plant has maximum useful value in its leaves, bark, flowers and fruits than any other tree species. These values include antiallergic, antidermatic, antifeedent, antifungal and anti-inflammatory properties. Due to the vast activities of neem, it has become extremely valuable in making our ecosystem a green treasure. Neem leaves have been demonstrated to exhibit immuno-modulatory, anti-inflammatory, antiulcer, antimalarial properties. Neem tree plant parts contain a promising pest control substance which has found effective use against economically important agricultural pests. Neem plant products are easy to process by village level industries on the micro scale level and use by resource poor farmers in crop protection resulting thereby in income generation. This plant also has antioxidant properties and free radical scavenging potential in its different extracted solvents. The present review highlights the properties of neem against the pathogens of living organisms for environmental protection.

Opis:: A ten-week experiment using twenty four (24) weaner rabbits (Chinchila x New Zealand White) aged 8 to 9 weeks with an average initial body weight of 431.20+0.74g were randomly allocated to four treatment diets of T1(control), T2(5% NLM), T3(10% NLM) and T4(15% NLM) in a completely randomized design. They were fed for 10 weeks during which data on growth and haematology were collected and analysed using analysis of variance (ANOVA) and means separated using Duncan Multiple Range Test. The results showed that the average total body weight gains were 739.60g (T1), 717.85g (T2), 740.18g (T3) and 729.45g (T4).There was no significant difference (p>0.05) when T1 and T3 as well as T2 and T4 were compared but significant (p<0.05) when T1 and T2 as well as T3 and T4 were compared. Also the average weekly feed intake showed that T1, T2, T3 and T4 consumed 313.91g, 313.24g, 312.48g and 314.69g respectively. However, there was significant difference (p<0.05) when all the treatments were compared in this respect. The feed conversion ratio (FCR) showed that T3 (4.22) was the best followed by T1 (4.24), T4 (4.31) and T2(4.36) with significant differences (p<0.05) among them except (p>0.05) between T1 and T3. The haematological indices showed that though all the parameters fell within the normal physiologic ranges, the PCV was 37.62% (T1), 38.42% (T2), 39.60% (T3) and 39.03% (T4) and when compared, were all significantly different (p<0.05) except (P>0.05) for T3 and T4 while the haemoglobin concentration showed that T1(13.47g/dl) was significantly different (p<0.05) from T2(14.18g/dl), T3(14.34g/dl), and T4(13.97g/dl). The white blood cell count showed that T3 (10.62 x109/L) had the highest value followed by T1 (10.12 x109/L), T4 (9.34 x109/L) and T2 (9.18 x109/L) with a significant difference (p<0.05) occurring when T1 and T3 were compared to T2 and T4 while the red blood cell counts indicated that T1 had the highest value of 4.92 x106/L followed by T3(4.89 x106/L), T2(4.73 x106/L) and T4(4.65 x106/L) without any significant difference among the treatments. All the values fell within the normal range. It is therefore recommended that inclusion of neem leaf meal in the diets of rabbits up to 10% is not detrimental since it improved feed conversion ratio (FCR), growth performance and had no negative effect on haematological values.

Opis:: Herein, the effect of applying different rates of inorganic fertilizer (NPK 20:10:10) and organic fertilizer (neem seed) and their combinations on plant nutrient concentration and yield of okra was studied under field conditions at two locations within the University of Calabar Teaching and Research Farm. The experiment was laid out in a randomized complete block design with three replications. Eleven treatments were applied. These were comprised of a control (no amendment), sole NPK 20:10:10 fertilizer and neem–based organic fertilizer applied at two rates (100 and 120 kg N/ha), combinations of 60 kg N/ha NPK+ 60 kg N/ha Neem, 50 kg N/ha NPK+ 50 kg N/ha Neem, 90 kg N/ha NPK + 30 kg N/ha Neem,25 kg N/ha NPK+ 75 kg N/ha Neem, 30 kg N/ha NPK + 90 kg N/ha Neem and 25 kg N/ha NPK+ 75 kg N/ha Neem. Amongst the two rates (100 and 120 kg N/ha) of sole application of either NPK or Neem-based organic fertilizer, the 120 kg N/ha recorded the highest number of fruits set and okra fresh fruit yield. The combination of 60 NPK + 60 Neem kg N/ha increased the yield (8.43 t/ha) and yield components of okra, while the 90 NPK + 30 Neem kg N/ha and 30 NPK + 90 Neem kg N/ha increased nutrient concentration in the okra plant. Thus, for sole application, the 120 kg N/ha application of either nutrient source is appropriate, but for optimum yield of okra in the tropical rainforest zone of Nigeria, the combination of both organic and inorganic fertilizer especially at 60 kg N/ha of each nutrient source, is recommended.

Opis:: Cutting fluids are used during metal cutting process to minimize the heat that is developed between tool, work piece and the chip. A good cutting fluid should absorb maximum heat from the machining zone. Heat absorption capacity of any cutting fluid used is measured by specific heat. Higher the specific heat better will the heat absorption capacity. This paper discusses a simple experimental procedure that is used to measure the specific heat of Neem oil, Honge (Karanja), Sunflower oil and Petroleum based oil (Hydro 68). This experiment is a function of temperature with respect to time. The rise in temperature with respect to time will determine the heat absorption capacity of fluids or oils or liquids. This method is validated by measuring the Specific heat of distilled water, the standard specific heat value of distilled water is 4.4 J/g/°C and measured value from the experiment is 4.5 J/g/°C. The results obtained are similar to the results observed by using other methods like TGA and DSC instruments. From the experiment the Specific Heat of Neem measured is 4.1032 J/g/°C which is high compared to Honge oil with the value of 2.3630 J/g/°C and Sunflower oil with 2.4311 J/g/°C, but less compared to hydro68 with value measured as 7.4850 J/g/°C.

Opis:: The aim of the present work was to assess an eco friendly natural antimicrobial textile finish extracted from Aloe gel and Neem plants. Extracted Aloe gel and active substance of Neem were mixed in a mordant to form a finish. Bleached cotton samples were treated with 5, 7, and 10% concentrations of Aloe gel and Neem separately. The same samples were then treated with a hybrid combination of Aloe gel and Neem (HCAN) extracts having 5, 7 and 10% concentrations. These finished samples were subjected to an antibacterial activity test against E. coli and S. aureus, an antifungal activity test against Aspergillus Niger, and a test of their durability of antibacterial finish fastness to washing by standard test methods. It was found that the hybrid combination of Aloe gel and Neem (HCAN) was an effective antibacterial and antifungal agent as compared to Aloe gel and Neem separately. It also showed good durability to washing.
Ekstrakty z żelu aloesowego i aktywnych substancji miodli indyjskiej mieszano w zaprawie barwiarskiej dla uzyskania gotowej preparacji. Bielone bawełniane próbki nasycano roztworem o stężeniu 5%, 7% i 10% żelu aloesowego i miodli indyjskiej. Te same próbki były następnie nasycane preparacją hybrydową zawierającą obydwa składniki o tym samym stężeniu. Uzyskane próbki poddano badaniom antybakteryjnym przeprowadzając testy przeciwko E. coli i S. aureus, i antygrzybicznej aktywności przeciwko Aspergillus niger. Niezależnie od tego przeprowadzano próby trwałości preparacji antybakteryjnych po praniu w standardowych warunkach. Stwierdzono, że preparacja hybrydowa obydwu składników była aktywniejsza zarówno w stosunku do bakterii i grzybów niż preparacje z użyciem jednego tylko składnika.

Opis:: Synthetic organic compounds and those of plant origin used in insect pest control are known to affect digestive enzymes and biochemical compounds. The lesser mulberry pyralid Glyphodes pyloalis Walker is a monophagous and dangerous pest of mulberry that has been recently observed in Guilan province, northern Iran. In this study the effect of the neem formulation, Achook (0.03% azadirachtin) was studied on nutritional physiology and gut enzyme activity of the lesser mulberry pyralid G. pyloalis. The LC25, LC50, and LC90 values on 4th instar larvae were estimated as 113.6, 256.84, and 1,210.02 ppm, respectively. The neem insecticide exhibited a significant antifeedant activity when used at the highest concentration. When G. pyloalis larvae were provided with mulberry leaves treated with the neem extract, all nutritional indices, except approximate digestibility, decreased. Neem was found to affect digestive enzyme activities in the midgut of treated larvae. When larvae were fed on treated leaves, biochemical compounds in the hemolymph, such as protein, lipid, and glucose decreased but the amount of uric acid increased compared with the control.

Opis:: Neem (Azadirachta indica A. Juss.) seed oil (NSO) is acclaimed to have some form of insecticidal action against more than 400 insect species in at least 10 to 13 orders. The main delimitating factor in the wide acceptance of this well tested plant as a storage pest bioinsecticide is its foul sulfurous smell and bitter taste which impinges on the acceptability and marketability of treated produce. To ameliorate this shortfall, therefore, an assessment of the potential of impregnating different storage materials; [plastic containers (PLC), Bagco bags (BCB), Black polyethylene bags (BPB), white polyethylene bags (WPB) and calico bags (CAB)], with NSO in the management of Callosobruchus maculatus (F.) in stored Bambara seeds (Vigna subterranea L.), was conducted in the laboratory. The experiment was laid out in a 4 x 5 factorial arrangement fitted into a completely randomized design (CRD). Factor A represented four concentrations of NSO (0.00, 0.50, 1.00, 1.50 ml/ 100g seed), while factor B were the five different storage materials. The treatments were replicated four times Generally, seeds stored with impregnated storage materials recorded more bruchids mortality, reduced oviposition rate, decreased number of emerged insects (F1 and F2) and had less damaged seeds (and hence decreased weevil perforation index, WPI) than the control. Concentration performance was dose related though the highest (1.50 %) did not differ statistically (P=0.05) from the medium (1.00 %) concentration. Seeds stored in BPBs had the highest mortalities, but recorded the lowest in number of eggs oviposited, egg/seed ratio, F1, F2 and cumulative emergence, respectively. These results differed significantly (P=0.05) with the seeds stored in other materials. BPB stored seeds were also the least damaged with lowest exit holes/seed, seeds with holes and WPI, respectively. The performance of BPB was closely followed by seeds stored in WPBs in all the parameters tested. Conversely, seeds stored in BCBs recorded the lowest mortalities but the highest in all other parameters assessed. Other storage materials (PLC and CAB) had better storage quality than BCB materials. Impregnation of storage materials with NSO could be a better option to direct seed application with its attendant drawback. The use of NSO impregnated black polyethylene bags, within the scope of the storage materials screened, to control damage by C. maculatus in stored Bambara seeds, should be encouraged.

Opis:: Azadirachtins are known as phagorepellent natural products from seeds of the neem tree Azadirachta indica A. Juss (Meliaceae), which impede the development of larval insects and sterilize adults. The labors of the past three decades ultimatively lead to a chemical structure, which has been unanimously but independently elaborated by German, British and American authors. This structure is in force ever since 1985/87 and was ultimately confirmed by Veitch & al. in Ley’s group in Cambridge, England, through total synthesis. Its 25th birthday is presently being celebrated. Marrangin (=Azadirachtin L) was discovered in Gießen and chemically identified by Kalinowski and colleagues. It occurs in seeds of the marrango tree, Azadirachta excelsa (Jack) Jacobs. In some insect species but also in mites like Tetranychus urticae, its biological activity is significantly superior to azadirachtin A. The value of these biorational compounds, with their very low vertebrate toxicity, and their low toxicity today is globally recognized. Quite recently, azadirachtin and analogues gain acceptance in veterinary and human medicine.

Opis:: With the revival of interest in natural products and the ‘back to nature’ call, researchers have started looking into the herbal literature of oriental civilisations, particularly those of India and China, in addition to European and other sources. In this article, I would like to introduce knowledge about two plants and their use in veterinary medicine. Melia azadirachta L. and Centella asiatica L., are a traditional plants known and used for medicinal and cosmetic purposes for thousands of years. Extracts of various parts of neem have proven its medicinal properties; antihelmintic, antifungal, antidiabetic, antibacterial, antiviral and antifertility. Neem use as an insecticide and pesticide was also well documented. The leaves and the whole herb of Centella asiatica, are used in Ajurveda medicine for thousands of years for improving memory and for treatment of central nervous system diseases, vasculo-cardiac disorders, chronic gastric ulcers, dermatopathies and hard healing wounds. The results of modern research have shown the merits of the application Centella asiatica in disorders of the nervous system, cardiovascular system, stomach ulcers, skin diseases and the positive effects on wound healing. Currently, for both presented plants, their therapeutic utilization is still under investigation.
