Opis:: Ascorbic acid is a well-known antioxidant found in plants. The content of ascorbic acid was assayed using a normal phase European Pharmacopoeia HPLC method for ascorbic acid in medicinal products. The content of ascorbic acid in herbs was calculated in % for absolutely dry drug. Ascorbic acid was not detected in the roots of Primula veris, in aerial parts it was detected in flowers (0.43 ± 0.034%), in blades (1.43 ± 0.11%) and petioles (1.56 ± 0.12%). In fresh leaves collected at weekly intervals the content of ascorbic acid varied from 1.19 to 2.39%, being highest from mid-May to mid-June. The fresh leaves contained 2.35 ± 0.18% of ascorbic acid and when frozen its content was quite stable for one year. The content of ascorbic acid in dried leaves decreased more than ten times in three months, in twelve months it was less than 1/20th of the initial level. Compared to the analyzed common fresh fruits and salads (n = 10) the fresh leaves of common cowslip contained considerably more ascorbic acid. Commercial orange juices could be recommended as the most convenient source of ascorbic acid (8.6–50.4 mg/100 ml); 1–5 glasses of orange juice could fulfill the recommended daily intake of vitamin C (60 mg).

Opis:: Freshly prepared garlic (Allium sativum L.) juice, containing the antimicrobial allicin, was evaluated as a possible grain pro-tectant against the maize weevil, Sitophilus zeamais (Motsch.). Each experiment was set out in Completely Randomized Design (CRD) with four replications, and there was a control treatment. Adult mortality and weight loss percentage were investigated. There was an observed increase in adult mortality following days of exposure in all treatments. Statistically significant (p < 0.05) reduced grain loss was also observed in all the treatments when compared with the control. The juice samples were freshly prepared from an indigenous Nigerian garlic cultivar (GUN) and a cultivar purchased from a supermarket in Germany (GAG). These garlic juice samples exhibited lethal effects causing at least 90% adult mortality in contact toxicity tests. The amount of allicin in GUN was 1.88 mg/ml according to High Pressure Liquids Chromatography (HPLC) analysis, while the amount of allicin in GAG was 3.50 mg/ml. This study highlights the potential of A. sativum containing allicin for biorational control of maize grains against S. zeamais infestation and damage.

Tytuł:: Uptake of Toxic Trace Metals (Cd, Pb) and Micro Nutrients (Cu, Zn, Mn) by Sugarcane (Saccharum Officinarum L.) Irrigated with Treated Effluents of Sugar Industry

Opis:: The accumulation and translocation of trace metals in soil and in sugarcane crop irrigated with treated effluents from sugar industry compared to soil and sugarcane crop irrigated with bore-well water were determined. In the present study the impact of irrigation with treated effluent from the sugar industry on the trace metal contamination of sugarcane juice was assessed. It revealed that the mean concentrations of Cd, Pb, Cu, Mn and Zn in the soil of fields irrigated with effluent and in juice from sugarcane grown on such fields were higher than those from bore-well water irrigated fields. The concentrations of trace metals in treated effluent exceeded the permissible limits of the Indian standards (Central Pollution Control Board-2000). The concentrations of Cd, Pb, Cu and Zn in juice of sugarcane grown on fields irrigated with effluent also exceeded the permissible limits of Indian standards and WHO/FAO expert committee recommendations. Their concentrations in juice of sugarcane grown in fields irrigated with bore-well water were within the limits of safety, except for Cd. The transfer factor for Zn was considerably higher than those of the other trace metals. The metal concentrations of sugarcane juice showed significant correlations with those of soil, which was not the case when bore well water was used for irrigation.
