dihydrocucurbitacin b/trichosanthes

From the fresh roots of Trichosanthes bracteata Voigt., the following substances were identified: methyl palmitate, palmitic acid, suberic acid, alpha-spinasterol, stigmast-7-en-3 beta-ol, alpha-spinasterol 3-O-beta-D-glucopyranoside, stigmast-7-en-3 beta-ol 3-O-beta-D-glucopyranoside, glyceryl

A mixture of alpha-spinasterol, stigmast-7-en-3-beta-ol (1) and its 3-O-beta-D-glucopyranoside (2), bryonolic acid (3), 23,24-dihydrocucurbitacin B (4), cucurbitacin B (5), cucurbitacin D (6) were obtained from the fresh roots of Trichosanthes multiloba Miq. (Cucurbitaceae). 1, 2, 4, 5 and 6 were

The root extract of Trichosanthes cucumerina L. and bryonolic acid (1), its main constituent, as well as the fruit juice and cucurbitacin B (3), its main constituent, were tested for cytotoxicity against four human breast cancer cell lines (SKBR3, MCF7, T47D, and MDA-MB435), two lung cancer cell

A multi-channel counter-current chromatography (CCC) method has been designed and fabricated for the high-throughput fractionation of natural products without complications sometimes encountered with other conventional chromatographic systems, such as irreversible adsorptive constituent losses and
