This article reviews, connected the gap between the folkloric use of Solanum nigrum and the results of evidence based experiments. Although Solanum nigrum is a rich source of one of plants most dreaded toxins solanine, it has appreciably monstrated its potential as a reservoir of antioxidants having hepatoprotective, anti-tumor, cytostatic, anti-convulsant, anti-ulcerogenic and anti-inflammatory.effects. The review encompasses in-vitro, in vivo and clinical studies done on Solanum nigrum, while examining.whether or not correct scientific measures have been taken in generating experimental evidences for its traditional uses. This review would afford research scientist to know how much is known and what is left undone in the investigation of Solanum nigrum. The compounds considered in this revieware flavonoids and other phenolics, alkaloids (especially indole terpenoid and purine alkaloids), essential oils and other terpenoids, cannabinoids, lucosinolates and isothiocyanates, and compounds having human hormone activity. The review concludes with a discussion of the possible evolutionary mechanisms that have led to the evolution of UV-B regulation of secondary metabolite accumulation. Many Ayurveda philosophers and healers...

Pollution have a serious impact on human health and environment. The incidences of various diseases are becoming prominent with the increase in rate of population. The diseases mainly include respiratory disorders, cardiovascular disorders, throat inflammation, skin infections etc. In the present study, widely claimed crude drug Dashamularishta, have been screened for their antibacterial activity against Shigella flexneri, Staphylococcus aureus, Salmonella typhi, Pseudomonas aeruginosa, Klebsiella pneumonia, Proteus vulgaris, Enterobacter aerogenes, Aspergillus niger, Candida albicans, Trichophyton rubrum. Phytochemical screening and antimicrobial activity of petroleum ether, chloroform, benzene, ethyl acetate and ethanol and distilled water extracts of Dashamularishta have been screened. Phytochemical screening recorded positive results for reducing sugar in all six extracts, terpinoids present in pet. ether, ethyl acetate, methanol and distilled water extract, Flavonoids present in ethyl acetate and distilled water, Tannin present in chloroform and methanol, saponins present in pet. ether, benzene, ethyl acetate and distilled water extract. The results were expressed in terms of the diameter of the inhibition zone: The maximum efficacy of ethyl acetate extract was...

The present study describes a simple, accurate, precise and cost effective UV-Visible spectrophotometric method for the estimation of Riboflavin raw material. The Riboflavin is water soluble vitamin, so the solvent used throughout the experiment was 0.1N NaOH, the absorption maxima of drug was found at 445 nm. Beer’s law was obeyed in the range of 5ppm-30ppm. the developed method was successfully validated with respect to linearity, accuracy and precision. The method was validated and shown linearity in mentioned concentration. The correlation coefficient for Riboflavin was 0.999. The percentage relative standard deviation of inter-day precision range 0.66-1.04% and intra-day precision 1.05-1.39% both should be less than 2%. Hence proposed method was precise, accurate and cost effective, simple and rapid. This validated method can be applicable for quantitative determination of the titled drug with respect to assay from or for their solid dosage...

Heterocyclic compounds are of very much interest in our daily life. Heterocyclic compounds have one or more hetero atoms in their structure. They may be cyclic or non cyclic in nature. Heterocyclic compunds have a wide range of application. They are predominantly used as pharmaceuticals, as agrochemicals and as veterinary products. They also find applications as sanitizers, developers, antioxidants, as corrosion inhibitors, as copolymers, dye stuff. They are used as vehicles in the synthesis of other organic compunds. Some of the natural products e.g. antibiotics such as penicillin’s, cephalosporin; alkaloids such as vinblastine, morphine, reserpine etc. have heterocyclic...

Plant polyphenols have been studied largely because of the possibility that they might underlie the protective effects afforded by fruit and vegetable intake against cancer and other chronic diseases. The objective of the present study is to estimate the total polyphenolic content in aqueous and methanolic extract prepared from the bark of Acacia nilotica plant species. Acacia nilotica (L.) Willd. ex Del commonly known as babul, kikar or Indian gum Arabic tree, has been recognized worldwide as a multipurpose tree. Mostly it occurs as an isolated tree and rarely found in patches to a limited extent in forests and has been widely planted on farms throughout the plains of the Indian subcontinent. The bark, root, gum, leaves and flowers have found use for skin diseases, diarrhoea, dysentery, cough, diabetes, eczema, wound healing, burning sensation and as an astringent, demulcent, anti-asthmatic. For present work the bark of well identified A. nilotica (L) plant for the extraction of phytochemicals was done from the village Khargawali (Hoshangabad district). 20-20 grams of the...
