A kuguaglycoside is one of several chemical compounds (cucurbitane triterpenoid glycosides) isolated from the roots of the bitter melon vine (''Momordica charantia'', ''kǔguā'' in Chinese) by J.-C. Chen and others.〔Jian-Chao Chen, Lu Lu, Xian-Ming Zhang, Lin Zhou, Zhong-Rong Li, and Ming-Hua Qiu (2008), "Eight New Cucurbitane Glycosides, Kuguaglycosides A–H, from the Root of ''Momordica charantia'' L.". ''Helvetica Chimica Acta'', volume 91, issue 5, pages 920-928. 〕 Kuguaglycosides are glycosides of triterpene derivatives, with the cucurbitane skeleton. They are colorless solids, soluble in methanol, ethyl acetate, and butanol.〔 They include: * Kuguaglycoside A: 3β-hydroxy-7β-methoxycucurbita-5,24-dien-23-yl β-glucopyranoside, 〔 * Kuguaglycoside B: 3β-hydroxy-25-methoxycucurbita-5,23-dien-7β-yl β-glucopyranoside, 〔 * Kuguaglycoside C: 7β-(β-glucopyranosyloxy)-3β-hydroxycucurbita-5,23,25-trien-19-al, (colorless needles)〔 * Kuguaglycoside D: 3β,19,23-trihydroxycucurbita-5,24-dien-7β-yl β-glucopyranoside, 〔 * Kuguaglycoside E: 23-(β-glucopyranosyloxy)-3β,19-dihydroxycucurbita-5,24-dien-7β-yl β-glucopyranoside, 〔 * Kuguaglycoside F: 23-(β-glucopyranosyloxy)-7β-methoxycucurbita-5,24-dien-3β-yl β-allopyranoside, 〔 * Kuguaglycoside G: 23-(β-glucopyranosyloxy)-3β-hydroxycucurbita-5,24-dien-7β-yl β-glucopyranoside, 〔 * Kuguaglycoside H: 23-(β-glucopyranosyl(1→2)-β-glucopyranosyl)-3β-hydroxycucurbita-5,24-dien-7β-yl β-glucopyranoside, (colorless needles)〔 Kuguaglycoside B is also found in the fruit of ''M. charantia''.〔Jie-Qing Liu, Jian-Chao Chen, Cui-Fang Wang and Ming-Hua Qiu (2009), "New Cucurbitane Triterpenoids and Steroidal Glycoside from ''Momordica charantia''".
