Momordin is one of several saponins derived from oleanolic acid, a triterpenoid. These chemical compounds are found in some plants of the ''Momordica'' genus, which includes the bitter melon (''M. charantia'') and the balsam apple (''M. balsamina''), as well as in other Asian herbal medicine plants such as ''Kochia scoparia'' and ''Ampelopsis radix''.〔 Momordins include: * Momordin I, oleanolic acid 3-''O''-α-''L''-arabinopyranosyl(1→3)-β-D-glucuronopyranoside. A white powder that decomposes at 235–240 °C. Found in the root of ''Momordica cochinchinensis'' were it constitutes 10% of the dried methanol extract. * Momordin Ia, from ''M. cochinchinensis''. * Momordin Ib, from ''M. cochinchinensis''.〔 * Momordin Ic or (3β)-17-carboxy-28-norolean-12-en-3-yl 3'-''O''-(β-D-xylopyranosyl)-β-D-glucuronide (), CAS number 96990-18-0. It is obtained as colorless fine crystals that decompose at 240 °C. It inhibits gastric emptying in mice.〔 * Momordin Id, from ''M. cochinchinensis''.〔 * Momordin Ie, CAS 96158-13-3.〔(Momordin Ie catalog entry ) at Trading Chem. Accessed 2011-01-01.〕 * Momordin II, the 28-''O''-β-D-glucopyranoside of momordin I. Colorless needles, soluble in methanol, that melt at 240−245 °C. Also from ''M. cochinchinensis''; identical to hemsloside Ma 1 from ''Hemsleya macrosperma'' and ''H. chinensis''〔 * Momordin IIa, from ''M. cochinchinensis''.〔 * Momordin IIb, from ''M. cochinchinensis''.〔 * Momordin IIc, either the same as oleanic acid〔(Momordin IIc catalog entry ) from NextBio. Accessed on 2011-01-01.〕 or (quinoside D) * Momordin IId, from ''M. cochinchinensis''.〔 * Momordin IIe, CAS 96158-12-2.〔(Momordin IIe catalog page ) at Look Chemical. Accessed on 2011-01-01.〕 * Momordin III, 3β-hydroxy-11α, 12α-epoxy-olean-28,13-olide 3-''O''-α-L-arabinopyranosyl(1→3)-β-D-glucuronopyranoside. Also from ''M. cochinchinensis''.〔 == See also == * Momordin (protein), unrelated enzymes (proteins) from ''Momordica'' and other plants. 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「Momordin (saponin)」の詳細全文を読む スポンサード リンク
