Opis:
Aboriginal plants and their information clubbed with their potentiality. Majority of the secondary metabolites are the basic therapeutics. Usually these establishes in higher plants are gratifying all the time more noteworthy in drug scheming. In the current report, 100 different solvent extracts of 20 aboriginal plant species from Hyderabad Karnataka region were screened for their leading constituents of secondary metabolites. As of each one of plant species particular part of five successive extracts were particular for the revealing of impending metabolites. Intended for the vetting of secondary metabolites the criterion tests undertaken i.e., cluster wise for alkaloids dragendroff’s, tannin for ferric chloride, phenolics for lead acetate, glycoside for keller-killiani test, flavonoids for NaOH and saponins for foam test. The obvious ranges of secondary metabolites in the vein of non-polar to polar have been pragmatic. The utmost detection of alkaloids, tannins established at non-polar range whereas in middle polar flavonoids, tannins have been noticed. Glycosides and saponins entirely found at high polar. The upshot of the in attendance report will be very much constructive for isolation of diverse group of resulting metabolites in accumulate the time, chemicals, vigour utilization in active fragment drug design.

Opis:
The study was carried out to evaluate the phytochemical constituents, antioxidant activity and the content of total phenolic and flavonoid in the methanolic extract from stem bark, root, and leaves of Rhizophora mucronata from Karangsong, Indramayu Regency, West Java, Indonesia. The antioxidant activity was evaluated using 2,2-diphenyl-1-picrilhydrazyl (DPPH) assay. Total phenolic and flavonoid contents were determined according respectively to Folin-Ciocalteau method, and aluminium trichloride method. The methanol extract from stem bark of R. mucronata contained secondary metabolite such as phenolic, flavonoid, tannin and saponin. The stem bark of R. mucronata showed the highest phenolic and flavonoid content and possessed a higher antioxidant activity (IC50 84.80 µg·m/L) than that of root (IC50 166.95 µg·m/L) and leaves (IC50 90.51 µgmL1). Total phenolic and flavonoid content in the stem bark of R. mucronata were 131.91 ±1.7 mg gallic acid equivalents/g and 902 ±0.7 mg quercetin equivalents/g, respectively.

Opis:
Finding healing power in plants is an ancient idea, and people of all continents and civilization have been using plants in one form or the other for poultices or as decoctions. Alangium salvifolium (Linn), family Alangeaceae, is a tree that grows in the wild throughout India. The plant has been used in the Indian traditional system of medicine for skin diseases (e.g. leucoderma), articular diseases, and anti-inflammation, anti-poisonous, anti-pyretic, and anti-emetic requirements. However, no scientific evidence is available regarding its antimicrobial activity. An investigation of Alangium salvifolium as an antimicrobial activity agent is the objective of our present study. The ATCC culture used in this study was collected from department of Microbiology, G.M.C., Bhopal (M.P.). Shade dried crude powder (200 grams) of seed of Alangium salvifolium was separately extracted with methanol in a soxhelt apparatus. The Antimicrobial activities were then studied by applying the Disc–Diffusion method. Our results indicate that the observed antimicrobial activity of the fraction appears to be due to unknown secondary metabolites in it. H.P.L.C. (high performance liquid chromatography) and chemical studies may, thus be useful in analyzing the presence of unknown secondary metabolites in the fractions.

Opis:
The natural occurrence of the shrimp (Penaeus monodon Fabricius, 1798) and seagrass (Cymodocea rotundata Asch. & Schweinf.) is found in the area of Indian Ocean, Indonesia, for central Pacific. Vibriosis can cause death in larvae, juvenile and adult shrimp almost close to 100%. Antibacterial substances from secondary metabolites are produced by plants and animals to reduce the use of synthetic antibiotics. The purpose of this research was to determine the ability of secondary metabolites contained in the bacterial extract of the association of sea grass Cymodocea rotundata (isolate code BA.1) to treat vibriosis in tiger shrimp (Penaeus monodon). This research was conducted at the Laboratory of Integrated Biotechnology and Laboratory of Aquaculture, Fisheries and Marine Sciences Faculty, Universitas Padjadajaran, and at the Brackish and Southern Ocean Aquaculture Development Center Pangandaran, from June to September 2018. The research method used was experimental, with completely randomized design (CRD) consisting of five treatments with three replications including; control treatment (concentration of 0 mg·L–1), 150 mg.L–1, 300 mg·L–1, 450 mg·L–1 and 600 mg·L–1. Observations made include clinical symptoms (morphology, behavior) and survival rate. Clinical symptoms of infected tiger shrimp during the in vivo test were red spots on the abdomen and necrosis of some leg and tail segments. The behavior of tiger shrimp mostly shows less responsive movements to fish-feed on the first day, and showing responsive and active behavior on the fifth day. In vivo test results for 14 days showed that the highest survival rate of 51.67% was in case of the addition of antibacterial extracts of BA.1 with a concentration of 300 mg·L–1.
