摘要：

Feeding experiments with deuterium-labelled 8-epi-deoxyloganic acid, bartsioside and aucubin gave incorporation of all compounds into catalpol both in Scutellaria albida and Paulownia tomentosa. Dilution experiments with labelled 8-epi-deoxyloganic acid and unlabelled aucubin showed that aucubin is an intermediate in the biosynthesis of catalpol in these two species. 8-epi-Deoxyloganic acid was incorporated into tomentoside in P. tomentosa.
