Charantoside is any of several related cucurbitane triterpenoid glycosides found in the fruits bitter melon vine (''Momordica charantia''). They include: * charantoside I, (19R,23E)-5β,19-Epoxy-19-methoxycucurbita-6,23,25-trien-3β-ol 3-O-β-D-glucopyranoside: amorphous solid. * charantoside II, (19R,23R)-5β,19-Epoxy-19,23-dimethoxycucurbita-6,24-dien-3β-ol 3-O-β-D-allopyranoside: amorphous solid. * charantoside III, (23E)-5β,19-Epoxycucurbita-6,23,25-trien-3β-ol 3-O-β-D-glucopyranoside: amorphous solid. * charantoside IV, (23E)-5β,19-Epoxycucurbita-6,23,25-trien-3β-ol 3-O-β-D-allopyranoside: colorless needles, melting at 256–260 °C. * charantoside V, (23R)-5β,19-Epoxy-23-methoxycucurbita-6,24-dien-3β-ol 3-O-β-D-glucopyranoside: colorless needles, melting at 235–240 °C. * charantoside VI, (23S)-5β,19-Epoxy-23-methoxycucurbita-6,24-dien-3β-ol 3-O-β-D-allopyranoside: amorphous solid. * charantoside VII, (23E)-3β-Hydroxycucurbita-6,23,25-trien-5β,19-olide 3-O-β-Dglucopyranoside: colorless needles, melting at 258–262 °C * charantoside VIII, (23E)-3β-Hydroxy-7β,25-dimethoxycucurbita-5,23-dien-19-al 3-O-β-D-glucopyranoside: amorphous solid. Charantosides I through VIII can be extracted from the fresh fruit with methanol and ethyl acetate.〔 == See also == * momordicoside * goyaglycoside * karaviloside * charantin 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Charantoside」の詳細全文を読む スポンサード リンク
