【Abstract】 Aim To study the bioactive components from Helicia nilagirica. Methods Compounds were separated with a combination of multi-chromatography. Their chemical structures were determined on the basis of spectral analysis and chemical evidence. Results Two compounds were isolated from the leaves of Helicia nilagirica. Compound 1 was elucidated as 1-O-β-D-glucopyranosyl-(2S,3S,4R,8Z)-2-[(2′R)-2′-hydroxylignocenoyl-amino]-8-octadecene-1,3,4-triol. Compound 2 was an analogue of 1. Conclusion The two compounds are new cerebrosides.更多还原
