摘　　要：选择福建省梁野山、龙栖山、闽侯旗山、南靖书洋乡和南平大坪村南方红豆杉(Taxus chinensis var.marei)天然群体分布相对集中区,采集胸径相同的南方红豆杉的当年生针叶和树皮并取树下土壤样品。利用超高效液相色谱分析测定南方红豆杉当年生针叶及树皮中紫杉醇及10-去乙酰基巴卡亭Ⅲ(10-deacetylbaccatin Ⅲ,10-DAB)含量,另测定土壤pH值、速效磷、速效氮、铁、钙、镁、锌含量。结果表明,不论是紫杉醇还是10-DAB含量,不同地理种源南方红豆杉间差异均较大,说明地理位置对于红豆杉中紫杉醇和10-DAB含量具有明显的影响;树皮中紫杉醇含量与土壤中铁含量显著相关(P<0.01);南方红豆杉当年生针叶中及树皮中紫杉醇含量与各种源地气象因子的相关性不显著(P>0.05)。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 ）.
