摘　　要：将灌冠红梅子根的乙醇提取物用甲醇溶解,加水,用石油醚萃取,采用GC/MS法进行分析。以峰面积归一化法计算各化合物在挥发油中的相对含量,共鉴定出个22化学成分,占总体含量的98.32%。主要成分有4-甲基-2-乙基己烷(14.79%)、反式-1-甲氧基-1-丁烯(13.41%)、2,3,3-三甲基己烷(10.24%)、(1-甲氧基-1-戊基)环丙烷(10.22%)、N,N-二甲基叔丁基胺(9.23%)、环己烷(8.55%)、1,1-二甲氧基-2-丁炔(6.34%)、2-甲基-2-乙基环氧乙烷(6.25%)、庚烷(4.38%)、正十一烷(3.6%)、1-碘正十四烷(2.6%)。Root of Rubus xanthocarpus was extracted with ethanol, followed by methanol dissolving. Then water was added to the methanol solution, and extracted by petrolic ether. The essential chemical components from Rubus Janthocarpus were analyzed by GC/ MS. Twenty-two components from Rubus Janthocarpus were identified by library search, which accounted for over 98.32 % of total volatile components. The main components are 4- methyl-2-ethylhexane （ 14. 79% ）, trans-1-methoxy-1-butene （13.41%）, 2,3,3-trimethyl- hexane （ 10.24% ）, （1-methoxy-1-pentyl） cyclopropane（10.22%）, N, N-dimethyl-t-butyl-amine （9. 23%）, cyclohexane （8. 55%）, 1,1-dimethoxy-2-butyne （6. 34%）, 2-methyl-2- ethyl ethylene oxide（6.25%）, heptane （4. 38%）, n-undecane （3. 6%）, 1-iodoteradecane （2.6%）.
