摘要从冬青叶中分离得到一个新的熊烷型三萜化合物(1),一个新的熊烷型三萜苷(2),一个新的齐墩果烷型三萜苷(3),沿着20个已知化合物。通过波谱分析和化学衍生,确定了这些天然产物的结构。我们的生物学评价确定了选择性化合物在1,1-二苯基-2-苦基肼和2,2 ′-连氮基-双(3-乙基苯并噻唑啉-6-磺酸)方法中显示出中等至显著的抗氧化活性。图形摘要
Abstract One new ursane-type triterpenoid (1), one new ursane-type triterpenoid glycoside (2), and one new oleanane-type triterpenoid glycoside (3), along with 20 known compounds, were isolated from the leaves of Ilex cornuta. The structures of these natural products were elucidated on the basis of detailed spectroscopic analyses and chemical derivation. Our biological evaluation established that selective compounds showed moderate to significant antioxidant activities in the 1,1-diphenyl-2-picrylhydrazyl and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) methods.
