| Abstract: |
| To study the chemical constituents from the n-BuOH part of the bark of Taxotrophis ilicifolia, sixteen compounds were isolated and purified from the n-BuOH part of the bark of T. ilicifolia by means of various column chromatographic techniques, including silica gel, ODS, Sephadex LH-20 and semi-preparative RP-HPLC. The structures of the isolates were identified by physiochemical properties and spectral data. The results were as follows: The compounds were identified as icariside E5(1), secoisolariciresinol 9-O-β-glucopyranoside(2), 2,4,6-trimethoxyphenol-1-O-β-D-glycoside(3),9-O-β-glucopyranosyl trans-cinnamyl alcohol(4), 3,4,5-trimethoxyphenyl-1-O-β-apiofuranosyl-(1″→6')-β-glucopyranoside(5),3-hydroxy-4,5-dimethoxyphenyl-β-D-glucopyranoside(6), 2,6-dimethoxy-4- hydroxyphenol-1-O-β-D-glucopyranoside(7), isotachioside(8), ficuscarpanoside A(9), uridine(10), methyl syringate 4-O-β-D-glucopyranoside(11), 3,4,5-trimethoxyphenyl-β-D-glucopyranoside(12), luteolin(13), ginsenoside Rg1(14),(+)-lyonirenisol-3α-O-β-D-glucopyranoside(15), myricetin 3-neohesperidoside(16). All compounds were isolated from plants of Taxotrophis for the first time. |
