Biopesticides, including entomopathogenic viruses, bacteria, fungi, nematoid’s, and secondary plant metabolites, are gaining increasing importance as they are alternatives to chemical pesticides and are a major component of many pest control programs. The virulence of various biopesticides such as nuclear polyhedrosis virus (NPV), bacteria, and plant products was tested under laboratory conditions very successfully, and the selected ones were also evaluated under field conditions with major...

Starch is a natural polymer and is a group of polysaccharides composed of glucopyranose units joined together by glycosidic linkages. Starch is an important polysaccharide extensively used in many industries like food, cosmetics, paper, textile, pharmaceutical, etc. It is found to be present in appreciable quantity in stem, roots, leaves, seeds, fruits, and tubers. Hence this study was conducted to isolate and characterize starch from the tuber of Antigonon leptopus species. In this work, starch from Antigonon leptopus tubers was extracted, and % starch yield was calculated as well as evaluated for its macroscopic characters, Preliminary phytochemical screening of aqueous extract for the presence of carbohydrate, tannins, saponins, and flavonoids. The result showed that there was a sufficient amount of starch yield. The compound microscope showed the presence of round and oval-shaped small and large starch particles, single as well as in groups. The diamond and prism-shaped calcium oxalate crystals were also seen. Thus, starch of tuber Antigonon leptopus species shows good properties and could serve as alternatives for...

Resveratrol (3, 5, 4′-trihydroxy stilbene) is a type of natural phenol, produced by several plants in response to injury or under attack by pathogens. These phytoalexin compounds are thought to have antioxidant, anticancer, and anti-inflammatory properties. Although resveratrol is commonly used as a dietary supplement, there is no conclusive evidence of whether or not resveratrol could be a viable treatment in humans. Despite the richness of in-vitro and in-vivo research, which confirms its potential therapeutic effects, there is insufficient clinical evidence on its beneficial results in humans. In this review, we have focused on the mechanism of action of resveratrol and on clinical trials that have evaluated the efficacy of reseveratrol in cancer, cardiovascular diseases and neurodegenerative...

Salacia oblonga wall, a native shrub, also known as Saptrangi and Ponkoranti, belongs to the family Celastraceae, is distributed across the world. A large number of chemical constituents such as salacinol, kotalanol, neokotalanol, neosalacinol, and mangiferin are isolated from S. oblonga, which show various pharmacological activities. Salacia oblonga wall is being used in several herbal preparations for treating diabetes and obesity. It possesses anti-inflammatory, antihyperlipidemic, antiperoxidative, antimicrobial, antimutagenic, nephroprotective, and antimutagenic activities. Salacia oblanga has a long history of use as a treatment for diabetes in Ayurveda, traditional Indian medicine. Mugs made from Salacia wood are used by people with diabetes to drink water. In addition to treating diabetes, Salacia is used for treating gonorrhea, asthma, itchiness, joint pain (rheumatism), obesity, thirst, and menstrual problems. Salacia oblonga, an inhabitant of tropical regions, has been used in traditional Indian medicinal systems. Phytochemicals were extracted in methanol from the plant and analyzed for various anticancer activity. This research focuses on extraction, phytochemical investigation of Salacia, and the potential of Salacia oblonga wall in breast cancer by using in-vitro anti-cancer testing...

The study was designed to investigate the pharmacognostic characters and phytochemical profile of crude drugs obtained from powdered aerial parts of Phyllanthus maderaspatensis L. (Madras nelli). The macroscopic, microscopic, phytochemical screening, and HPTLC studies of powdered aerial parts of the plant were carried out. Powder microscopy of aerial part powder of Madras nelli showed an isocytic type of stomata and with the straight cell wall. Treatment of aerial parts powder of Madras nelli showed a positive test for starch, tannins, and lignins, whereas negative for oil globules and crystals. Loss on drying was 5%, Total Ash value, and Acid – insoluble Ash value was found to be 10% and 2%, respectively. Aqueous and Alcohol extractive values were found to be 11.80% and 9.80%, respectively. The phytochemical screening test revealed for the presence of carbohydrates and in ethanol and water extracts, phytosterols in ether extract, flavonoids, and tannins in ethanol extract and saponins in ethanol and water extract. HPTLC study of the alcoholic extract revealed five phytoconstituents at Rf -0.49,...
