Abstract: The Liangye Mountain, Longqi Mountain, Qishan Mountain, Shuyang village, and Daping village in Fujian Province, where relatively concentrated with Taxus chinensis var. marei, were selected as the sites to collect the 1-year-old needle and bark samples of same DBH T. chinensis var. marei trees and the soil samples under the trees. The taxol and 10-DAB contents in the needles and barks were measured with UPLC, and the soil properties including pH, available phosphorus, available nitrogen, iron, calcium, magnesium, and zinc were measured. The results showed that different provenance T. chinensis var. marei had greater differences in the taxol and 10-DAB contents in its 1-year-old needles and barks, suggesting the obvious effects of geographical location. The taxol content in barks had significant correlation with soil iron content (P＜001), but the taxol and 10-DAB contents in needles and barks had less correlation with the local climate parameters of the provenances (P＞005).
