Isolation of Spinasterol and its Glucoside from Cell Suspension Cultures of Saponaria officinalis: 13C-NMR Spectral Data and Batch Culture Production.
Spinasterol and spinasteryl glucoside have been isolated as the exclusive sterols from cell suspension cultures of SAPONARIA OFFICINALIS and identified by MS, (1)H-NMR and (13)C-NMR spectral data. This result confirms the taxonomical vicinity of this plant to Chenopodiaceae and Amaranthaceae where Delta (7)-sterols were also described to be present. With more than 44% of total sterol content, the spinasteryl glucoside content is higher than in most of the common plants. This shows a particularly active glycosylation process probably in relation with the biosynthesis of saponosides.
