  Resin glycosides. VII. Reinvestigation of the component organic and glycosidic acids of pharbitin, the crude ether-insoluble resin glycoside ("convolvulin") of pharbitidis semen (seeds of Pharbitis nil).

  摘要：

  Alkaline hydrolysis of the ether-insoluble resin glycoside ("convolvulin") fraction, pharbitin, of the seeds of Pharbitis nil (Convolvulaceae) provided three organic acids, S-2-methylbutyric acid, (2R, 3R)-nilic acid and tiglic acid, and a new glycosidic acid named pharbitic acid B along with the known compounds pharbitic acids C and D. Pharbitic acid B was characterized as (3S, 11S)-3, 11-dihydroxyhexadecanoic acid 11-O-α-L-rhamnopyranosyl-(1→3)-O-β-D-quinovopyranosyl-(1→4)-O-α-L-rhamnopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→2)-[O-α-L-rhamnopyranosyl-(1→6)]-β-D-glucopyranoside. The structures of the sugar moieties of pharbitic acids C and D were revised.

These compounds (1–11) were considered to be generated via methyl esterification of the carboxyl group in acylated glycosidic acids. Their structures including stereochemistry were elucidated on the basis of a combination of the spectroscopic and chemical
