Chemical Component Study of Herb Pairs in Traditional Chinese Medicine
--Analysis of Volatile Oil in Rhizoma Ligustici Chuanxiong-Radix Paeoniae Rubra by GC-MS and Chemometric Resolution Method

Abstract

Abstract:

The volatile chemical components of herb pair Rhizoma Ligustici Chuanxiong-Radix Paeoniae Rubra(RLC-RPR) were analyzed by gas chromatography- mass spectrometry(GC-MS),chemometric resolution method(CRM),and overall volume integration methods. By using these methods upon two-dimensional data,52,33,and 61 volatile chemical components in the essential oil of RLC,RPR,and herb pair RLC-RPR were,respectively,determined qualitatively and quantitatively,accounting for 95.14%,95.82% and 90.18% of the total contents of the essential oil of RLC,RPR and herb pair RLC-RPR,respectively. The experimental results show that the volatile chemical components of herb pair RLC-RPR in number are almost the addition of that of two single drugs RLC and RPR,but are changed in contents.

Key words: Herb pair Rhizoma Ligustici Chuanxiong-Radix Paeoniae Rubra; Volatile oil; GC-MS; Chemometric resolution method(CRM)
