Study on Chemical Constituents of Volatile Oils in Drug Pair of Flos Lonicerae and Fructus Forsythiae by GC-MS / 中药新药与临床药理

ABSTRACT

Objective To discuss the influence of drug compatibility on the components of the volatile oil in Flos Lonicerae and Fructus Forsythiae. Methods GC-MS system was used to analyze the volatile oil in Flos Lonicerae, Fructas Forsythiae and their combination. The effect of compatibility on the components and content of volatile oil was evaluated. Results The results of GC-MS showed that gerani]o, tetradecanoic acid methyl ester, hexadecanoic acid ethyl ester, fluoranthene, 9, 12, 15-Octadeeatrienoic acid ethyl ester and linoleic acid was detectable in Flos Lonicerae but was undetectable in the drug pair; camphene, alpha-terpinene, perillaalcohol, 2-beta-pinene, beta-hexadecanal, phellandrene was de-tectable in Fructus Forsythiae but was undetectable in the drug pair; limonene, isolongifolene, nonadecane was detectable in the drug pair but was undetectable in the two single drugs. Conclusion The compatibility of the drug pair has an effect on components and contents in the volatile oil of Flos Lonicerae and Fructus Forsythiae.
