As we are well aware that the production of metallic nanoparticles by the physical and chemical method has numerous drawbacks along with the use of toxic chemicals, high energy expenditure and non- biodegradable products. Hence, researchers are showing great interest in the biological synthesis of nanoparticles. The biological method provides clean, bio-degradable, non-toxic and eco-friendly methods for nanoparticles synthesis as compared to a conventional method like physical and chemical. This review concentrates on biological method specially biosynthesis of different types of nanoparticles using bacteria and their application in different...

Flavonoids are common plant constituents used extensively in phytomedicine to treat a wide range of diseases. Many pharmacological pieces of evidence suggest that flavonoids may play an important role in the decreased risk of chronic diseases associated with a diet rich in plant-derived foods. Therefore, this article focuses on the chemistry, distribution and pharmacological properties of rhoifolin as one of the common and important flavonoids in the plant kingdom. This flavonoid has also been found in several dietary sources such as bitter orange, bergamot, grapefruit, lemon, lupinus, lablab beans, tomatoes, artichoke, bananas, and grapes. Preclinical studies have shown that rhoifolin possesses a variety of significant biological activities including antioxidant, anti-inflammatory, antimicrobial, hepatoprotective and anticancer effects. The literature search was conducted using electronic databases (e.g., Medline, Pubmed, Academic Journals and Springer Link), general web searches were also undertaken using Google applying some related search, journals and scientific theses. The bibliographies of papers relating to the review subject were also searched for further relevant...

Tea is composed of many compounds. These components have various effects depending upon the amount of tea ingested and the quality of the tea apart from that green tea having various useful properties which are helpful for the human body. The present communication describes about the about the “the comparative data between various brands of tea powders and green tea by using U.V. Spectrophotometer and TLC procedure for the estimation of caffeine content in commercial available tea samples and comparative data of caffeine content along with analysis of different brands of tea samples by comparing with the green tea powder. The present methods show a detailed description of the difference between commercial brands of tea powders and green tea. A possible explanation to account for the variability in green Tea and analysis of different samples is...

Cassia fistula Linn. (Family Leguminosae, Subfamily Caesalpinia), a very common Indian plant is known for its medicinal properties. This plant is also known as Indian Laburnum, Yellow shower because of its characteristic yellow flowers in pendulous raceme and with typical branches. It is a native of Tropical Asia. It is widely cultivated in South Africa, Mexico, East Africa, and Brazil. This plant is used in folk medicine for tumors of the abdomen, glands, liver and throat cancer. It is also used to cure burns, constipation, convulsions, diarrhea, dysuria, and epilepsy. Ayurvedic medicines recognize as carminative and laxative. It is also used to cure leprosy, skin diseases and syphilis. Phytochemical investigations prove its importance as an important, valuable medicinal plant. C. fistula is known to be an important source of secondary metabolites notably phenolic compounds. It is known as a rich source of tannins, flavonoids, and glycosides. Pharmacological activities include antibacterial, antidiabetic, antifertility, anti-inflammatory antioxidant, hepatoprotective, antitumor, antifungal activities. This article aims to provide a comprehensive review of morphology, traditional...

Objective: Phytochemical and pharmacological investigation on the leaves of Mimusops elengi Linn. for wound healing and in-vivo antioxidant activity in albino mice. Material and Methods: The methanolic extract of leaves of Mimusops elengi was studied for its wound healing effect on excision wound model in mice and in-vivo antioxidant activity at the dose level using a biochemical estimation of blood serum in mice. Result: Preliminary phytochemical analysis revealed the presence of saponin, carbohydrate, glycosides, flavonoids, tannin and phenolic compounds. Mimusops elengi methanolic extract (MEME) was examined for wound healing activity in the form of ointment in excision wound model in mice. The extract ointment showed a considerable response in the above model as compared to standard drug Betadine ointment regarding wound contracting ability, wound closure time. Histological analysis was also consistent with the proposal that Mimusops elengi leaf extract exhibits significant wound healing effect. As antioxidant action has been reported to play a crucial role in the hepatoprotection in in-vivo model of antioxidant activity. It has been found that...
