Abstract:
Object To study the chemical constituents of Stelmatocrypton khasianum (Benth.) H. Baill.. Methods Some constituents were isolated by chromatographic methods and identified by physicochemical constants and their structures were elucidated by spectral data. Results Seven compounds were isolated from the stem of S. khasianum and their structures were identified as ?-sitosterol-3-O-?-D-glucoside-6′-O-eicosanate (Ⅰ), 2?, 3?, 23-trihydroxy-olean-12-ene-28-oic acid (Ⅱ), 2?, 3?, 23-trihydroxy-urs-12-ene-28-oic acid (Ⅲ), ?-sitosterol-3-O-?-D-glucoside (Ⅳ), stearic acid (Ⅴ), glucose (Ⅵ), and sucrose (Ⅶ) respectively. Conclusion All compounds were obtained from this plant for the first time, and compound I is new.
