阔带凤丫蕨倍半萜类化学成分研究

目的:研究阔带凤丫蕨的化学成分。方法:采用色谱法进行分离,根据理化性质和波谱数据鉴定化合物的结构。结果:分离得到15个化合物,包括10个倍半萜类化合物,分别是(3S)-蕨苷D(1),表蕨素L(2),蕨素D(3),金粉蕨亭(4),蕨素Z(5),onitisin(6),onitisin-glucopyranoside(7),onitin-15-O-β-D-glucopyranoside(8),(2S,3R)-pterosin-L-2’-O-β-D-glucopyrano-side(9),(3R)-peterosin D-3-O-β-D-glucopyranoside(10),其他化合物分别是尿嘧啶(uracil,11),3,4-二羟基苯甲醛(3,4-di-hydroxybenzaldehyde,12),5-羟甲基糠醛(5-hydroxymethyl-2-furancarboxaldehyde,13),β-谷甾醇(β-sitosterol,14),胡萝卜苷(dau-costerol,15)。结论:以上15个化合物均为首次从阔带凤丫蕨中分离得到,其中9个化合物首次从凤丫蕨属中得到。

Sesquiterpenoids of Coniogramme maxima

Objective: To study sesquiterpenoids of Coniogramme maxima.Method: Chemical constituents were separated by chromatography and their structures were identified according to physicochemical property and spectrum data.Result: Fifteen compounds were separated by chromatography technique.Their structures were determined by spectral data,including 10 sesquiterpenoids as(3S)-pteroside D(1),epi-pterosin L(2),pterosin D(3),onitin(4),pterosin Z(5),onitisin(6),onitisin-glucopyranoside(7),onitin-15-O-β-D-glucopyranoside(8),(2S,3R)-pterosin-L-2′-O-β-D-glucopyranoside(9) and(3R)-peterosin D-3-O-β-D-glucopyranoside(10).The other compounds were uracil(11),3,4-dihydroxybenzaldehyde(12),5-hydroxymethyl-2-furancarboxaldehyde(13),β-sitosterol(14) and daucosterol(15).Conclusion: The above 15 compounds are separated from C.maxima for the first time,including 9 compounds being first separated from genus Coniogramme.
