摘要：
Deoxy-[6,7,8,10-H-2] loganic acid and 8-epideoxy-[6,7,8,10-H-2] loganic acid were fed to Thunbergia alata. The former was incorporated into stilbericoside with retention of the label at H-6, H-7 and H-8. Administration of deuterium-labelled loganic acid, adoxosidic acid, capensioside and 8(S)-bisdeoxy-7,8-dihydroaucubin showed that the first steps in the biosynthesis of stilbericoside from deoxyloganic acid are most probably 10-hydroxylation followed by decarboxylation.
