Abstract:
To study the chemical constituents of Periplocae Cortex, the separation and purification of 70% alcohol extract were carried out by column chromatographies on AB-8 macroporous resin, silica gel and preparative HPLC. The structure of the compounds were identified by NMR and TOF-MS. A new compound was isolated and identified as 21-O-methyl-Δ5-pregnene-3β, 14β, 17β, 21-tetraol-20-one-3-O-β-D-oleandropyranosyl(1-->4)-β-D-cymaropyranosyl-(1-->4)-β-D-cymaropyranosyl (1), named as periplocoside P.
