2026-04-24 Two new oxo-eudesmane sesquiterpenes from Yao medicine Cissampelopsis spelaeicola-raw data doi:10.57760/sciencedb.nprd.00126 en To clarify the chemical constituents and anti-inflammatory activity of the Yao medicine Cissampelopsis spelaeicola, the ethyl acetate fraction of this plant was isolated and purified using silica gel column chromatography and semi-preparative high-performance liquid chromatography. The structures of the compounds were identified by modern spectroscopic methods including NMR and HR-ESI-MS. The anti-inflammatory activities of the new compounds were evaluated by the CCK-8 method. The seven identified compounds were: 3'-angeloyl-O-β-D-glucopyranosyl-O-11-carissone (1), 6'-O-angeloyl-O-β-D-glucopyranosyl-O-11-carissone (2), carissone (3), syringaldehyde (4), coniferaldehyde (5), sinapoyl aldehyde (6), and coniferyl alcohol (7). Compounds 1 and 2 were identified as new oxo-eudesmane sesquiterpenes.  NMR; MS; chemical Gong Zhiqiang PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
