[Determination of taxol in aril of Torreya grandis cv. merrilli].
OBJECTIVE
To determine taxol in aril of Torreya grandis cv. merrilli.


METHODS
Extracts from Torreya grandis cv. merrilli were obtained by cold extraction and soxhlet extraction with ethanol, butyl acetate and chloroform as solvent. The content of taxol in extracts was determined by HPLC, and whether components similar with taxol existed in which was detected by FIA-MS.


RESULTS
The content of taxol in aril of Torreya grandis cv. merrilli is below 0. 003%. No components similar with taxol were clearly detected.


CONCLUSIONS
There is little value for Torreya grandis cv. merrilli as the resource of taxol.
