摘要
目的研究油茶茎的化学成分。方法利用硅胶、ODS、Sephadex LH-20葡聚糖凝胶柱色谱、高效制备液相色谱等色谱方法进行分离纯化,根据理化性质及波谱数据鉴定化合物结构。结果从油茶茎中分离得到3个化合物,分别鉴定为3-O-β-D-半乳糖基-(1→2)-[β-D-半乳糖基-(1→2)-β-D-木糖基-(1→3)]-β-D-葡萄糖醛酸基-3β,15α,16α,22α,28-五羟基-22-O-当归酰基-齐墩果-12-烯(1)、camelliasaponin B2(2)、gordonsaponin H(3)。结论化合物1为新化合物,命名为油茶皂苷Aa,化合物2和3为首次从油茶茎中分离得到。
Objective To study the chemical constituents of the stem of Camellia oleifera. Methods Thechemicalconstituentswere isolated and purified by column chromatography on silica gel, ODS, Sephadex LH-20, and PHPLC. Their structures were elucidated on the basis ofphysicochemical properties and special analysis. Results Three compounds were isolated from the stem of C. oleifera and elucidated as 3-O-β-D-galactopyranosyl-（1→2）-[β-D-galactopyranosyl-（1→2）-[β-D-xylopyranosyl-1→3）-[β-D-glucuronopyranosyl-3β,15α,16α,22α,28-pentol-22-O-angeloyloxy-olean-12-ene （1）, camelliasaponin B2 （2）, gordonsaponin H （3）. Conclusion Compound 1 was a new compound, and compounds 2 and 3 were isolated from the stem of this plant for the first time.
