Abstract :
Lupeol, a pentacyclic triterpenoid, was isolated from hexane and ethyl acetate solvent system. In antiquity, the stem and leaf infusion of Tapinanthus globiferus has been used ethno-medicinally as a remedy for stomach ache, diarrhea, dysentery, and wounds. Lupeol isolation from this species was carried out by column chromatography after concentrating the crude extract using a rotary evaporator, and the structure was determined by analysis of the isolate by IR, 13CNMR, 1HNMR, HSQC, and HMBC spectral analysis as well as comparison with reported data. This is the first isolation of lupeol from the stem of this species.
