萜类生物碱

二萜类生物碱的药理作用及构效关系研究概况

Pharmacological functions of diterpenoid alkaloids and their relationships between structure and effect

根据倍半萜类生物碱的溶解性，利用乙酸乙酯提取雷公藤，采用沉淀法以及氧化铝固相萃取方法获取总生物碱组分。

Total alkaloids were obtained from ethyl acetate extract by using precipitation and solid phase extraction methods .

本主综述了二维核磁共振谱在测定二萜类生物碱结构中的最近进展。

The up-dated applications of2D & NMR techniques in determining the structures of some diterpenoid alkaloids are reviewed .

比较6月与10月份同为GAP基地采集的雷公藤样品，结果10月份采集样品二萜类、生物碱类及三萜类含量均高于6月份采集的样品，再次验证了雷公藤合理的采收季节为秋季。

In comparison of the samples collected in different seasons from the GAP base , the contents of diterpene , alkaloids and triterpenes were all higher in October than in June , proving that the reasonable harvest season of T. wilfordii is in autumn .

随着萜类吲哚生物碱代谢途径中一些关键酶基因被克隆，使得利用代谢工程在植物细胞中生产这些生物碱成为可能。

With some key enzymes being cloned in the TIAs biosynthetic pathway , it is possible to produce the alkaloids in the plant cell by the metabolic engineering .
