A new HPTLC method has been developed for the identification and quantification of ursolic acid in apple peel extract. Ursolic acid can be easily estimated after derivatization with Liebermann TABLE 1: RECOVERY STUDY OF URSOLIC ACID FROM MALUS DOMESTICA PEEL Amount spotted (μg) Peak area (AU) Amount detected (μg) RSD (%) Accuracy (%) 0.91 4098.7 0.91 1.12 100.9 1.14 4677.5 1.13 1.48 99.6 1.36 5...

A simple highly precise method has been established for the determination of ursolic acid in three species of Swertia viz. S. angustifolia, S. paniculata, and S. alata. The assay combines identification and quantification of the analyte on silica gel 60GF254 HPTLC plates with visualization under UV light and scanning at 510 nm.

Tuberculosis still remains a leading cause of death in the world. Currently considerable interest in natural products and their derivatives in the area of drug research for multidrug resistant tuberculosis (MDR-TB). The present investigation focused on identification, isolation, characterization of lead constituents and to determine the antitubercular activity of their enriched fractions and is...

Abstract: Introduction: Urolithiasis has afflicted human race since the days of yore. Conventional treatment acts only on associated ailments whereas pharmacologically active phytoconstituents derived from plants are reported to possess lithotriptic as well anti-urolithiatic effect, thus herbal sources need be scientifically explored. Present study was aimed evaluate potential leaves Alstonia s...

background and objectives: betulinic acid (ba), oleanolic acid (oa) and ursolic acid (ua) are well-known pentacyclic triterpenoids (pts), which are produced by plants. they possess a variety of beneficial effects including anti-inflammatory, hepatoprotective, antitumor, anti-hiv, antimicrobial, gastroprotective, and antihyperlipidemic activities. in the present study, quantitative determination...

In this study, the effects of combining ursolic acid + resveratrol, for possible combined inhibitory effects on skin tumor promotion, were evaluated. Ursolic acid, resveratrol, and the combination of ursolic acid + resveratrol were applied topically prior to 12-O-tetracanoylphorbol-13-acetate (TPA) treatment on mouse skin to examine their effect on TPA-induced signaling pathways, epidermal hype...
