Abstract
The samples of Taxus yunnanensis from southeast Tibet were collected. The anti-cancer component contents in plant of Taxus yunnanensis such as taxol, baccatin Ⅲ, 10-deacetylbaccatin Ⅲ, cephalomannine, 10-deacety-7-epi-taxol and 7-epi-taxol were analyzed by HPLC. The result indicated that the correlation coefficients between of taxol and 7-epi-taxol, 7-epi-taxol and baccatin Ⅲ were 0. 852 and 0. 827. Their positive correlation was markedly in the 0. 001 levels. The correlation coefficient between taxol and baccatin Ⅲ was 0. 716. Their positive correlation was markedly in the 0. 05 levels. The contents of taxol had a significantly correlation with 7-epi-taxol. The contents of 7-epi-taxol had a significantly correlation with baccatin Ⅲ. The regression coefficients between taxol and 7-epi-taxol, 7-epi-taxol and baccatin Ⅲ were 0. 852 and 0. 827. The contents of taxol in 3 years old shoots and 1 year old needles were significantly different at 0. 05 levels. The contents of taxol in barks and 1 year old needles, 3 years old shoots and 1 year old needles were not significantly different at 0. 05 levels.
