Green barks and young needles of Taxus yunnanensis Cheng et L.K. Fu from different localities of Yunnan Province were analysed for taxol and other 4 taxane diterpenoids by HPLC. The average content of taxol in T. yunnanensis is 0.0081% in the dry barks. No obviously different taxol content is present in male or female plants. The taxol content in bark of wide diameter trunk is higher. The content of other 4 taxane diterpenoids (baccatin Ⅲ, taxuyunnanine A, 10 deacetyltaxuyunnanine A, 10 deacetylcephalomannine) is low.
