姜黄非药用部位化学成分的研究

目的]研究姜黄(Curcuma longa L.)非药用部位的化学成分。方法]采用硅胶柱色谱、葡聚糖凝胶柱色谱和高效液相色谱等方法对姜黄非药用部位化学成分进行分离纯化,通过波谱数据鉴定所得化合物结构。结果]从姜黄非药用部位中分离鉴定了5个化合物,通过波谱解析分别鉴定为3-吲哚甲醛(1)、光色素(2)、3-O-(α-D-半乳糖)-(1″→6')-O-β-D-半乳糖苷–丙三醇(3)、姜糖脂A(4)和noralpindenoside B(5)。结论]5个化合物均是首次从姜黄非药用部位分离得到,其中化合物1和5为首次从该属植物中分离得到。

Study on Chemical Constituents of Non-medicinal Parts of Curcuma longa

Objective]To study the chemical constituents of non-medicinal parts of Curcuma longa.Method] The chemical constituents of non-medicinalparts of C.longa were isolated and purified by silica gel column chromatography ,dextran gel column chromatography and high perform-ance liquid chromatography (HPLC).Chemical structures of these compounds were analyzed based on spectral data.Result] Five compounds were isolated from C.longa,including indole-3-carboxaldehyde (1),lumichrome (2),3-O-(α-D-galactopyranosyl)-(1″→6′)-O-β-D-galactopyr-anosyl-glycerol (3),gingerglycolipid A (4) and noralpindenoside B (5).Conclusion]The five compounds were isolated from non-medicinalparts of C.longa for the first time,compounds1 and 5 were isolated from Curcuma for the first time.
