ABSTRACT
Menthol is the most commonly used substance in many cosmetics and pharmaceutical products either as an active ingredient or in the form of excipient. In the present study, different samples of commercially available peppermint oil were subjected to standardization by determination of physicochemical characteristics, acid value, and resinified oil content. Thin layer chromatography [TLC] has been used to confirm the presence of menthol. The result showed that the quality control test performed for the evaluation of the physicochemical parameters of peppermint oil can be considered useful in its standardization. The results of acid value and the resinified oil tests, carried out on the raw material, have found to be within the standard limits. The results indicated specified number of free fatty acids and absence of greasy impurities. The data obtained from the study would be useful in the authentication of the commercial peppermint oil samples. In TLC studies, the Rf value of the active constituent has been determined by comparison with its standard spot. This technique may be used as a tool for the correct identification of the active constituent which could help in the standardization of the peppermint oil samples
ABSTRACT
The herbal system of medicine has gained worldwide importance due to its safety and efficacy considerations. Herbal medicines have been used for treating various diseases since ancient times. The present article deals with the importance and method of standardization of herbal medicines in order to ensure their purity, safety and efficacy. A detailed introduction regarding various aspects of the herbal system of medicine and methods of achieving quality of herbal medicine has been presented The various quality control methods recommended by World Health Organization have been described. Effort has also been made to focus on the physical, chemical and biological evaluation to achieve a high standard of quality for herbal medicine
ABSTRACT
Diabetes affects a large number of populations worldwide and the prevalence of this disease is rapidly increasing
Despite the availability of allopathic medications for diabetes, traditional remedies are desirable and are currently being investigated. Garlic [Allium sativum] has been reported to have antidiabetic activity. Evidences suggest that garlic has antioxidant, anti-inflammatory and antiglycative properties due to which it plays an important role in preventing diabetes progression and the development of diabetes-related complications. Large scale clinical studies with diabetic patients have been carried out to confirm the usefulness of garlic in the treatment and prevention of this disease. This article briefly reviews on the above stated subjected and the papers have been collected from internet resources including Pubmed, American Journal of Medicine, New England Journal of Medicine, Google Scholar and Journal of Medicinal Plant Research
