Comparative in vitro Study of Relative Anesthetic Potency of Ropivacaine and Lidocaine

Simultaneous Estimation of Four Antitussive Components from Herbal Cough Syrup by HPTLC

A new simple, rapid, selective and precise high performance thin layer chromatographic (HPTLC) method has been developed for simultaneous estimation of vasicine, glycyrrhizin, eugenol, and cineole in herbal cough syrup. The retention factors of vasicine, glycyrrhizin, eugenol, and cineole are 0.53, 0.44, 0.75, and 0.77, respectively. Chromatography was performed on 60F254 percolated TLC plate using n-hexane : ethyl acetate : glacial acetic acid (8.5 : 1.0 : 0.5 v/v/v). Methods are validated according to ICH guidelines and can be adopted for the routine analysis of vasicine, glycyrrhizin, eugenol and cineole in herbal cough syrup.

The chemotherapeutic effect of essential oil of Plectranthus amboinicus (Lour) on lung metastasis developed by B16F-10 cell line in C57BL/6 mice

Current investigation is to evaluate the anticancer activity of the essential oil of Plectranthus amboinicus (Lour) on B16F-10 melanoma cell line injected C57BL/6 mice, and it was simultaneously treated with the essential oil of P. amboinicus (Lour) (50 μg/dose) via i.p. for 21 days. The present investigation exhibited the potent chemotherapeutic/chemopreventive effect of the essential oil of P. amboinicus (Lour) over lung metastasis that developed. To our knowledge, this is the first report in evaluating the effect of essential oil of P. amboinicus (Lour) using lung cancer model.
