松节油主含α-蒎烯,用于肌肉痛及关节痛,许多进口药用油均以α-蒎烯含量作为质量指标。松节油在中国药典1995版(一部)有收载,但没有含量测定方法。本文采用气相色谱法测定松节油中α-蒎烯的含量。1 仪器与试剂 日本岛津GC-14B气相色谱仪;C-R4A色谱数据处理机;正丁醇(内标物)为分析纯;对照品α-蒎烯(东京化学工业株式会社)、石油醚
Turpentine oil contains α-pinene, which is used for muscle pain and joint pain. Many imported medicinal oils use α-pinene content as a quality indicator. Turpentine is included in the Chinese Pharmacopoeia 1995 (Part 1), but there is no content determination method. In this paper, the content of α-pinene in turpentine was determined by gas chromatography. 1 Instruments and reagents Shimadzu GC-14B gas chromatograph; C-R4A chromatographic data processor; n-butanol (internal standard) as analytical grade; reference alpha-pinene (Tokyo Chemical Industry Co., Ltd.), petroleum ether
