[Studies on GC fingerprint of volatile oil of Houttuynia cordata].Zhongguo Zhong Yao Za Zhi. 2006 Dec; 31(24):2055-7.ZZ
To establish a GC fingerprint of the volatile oil of Houttuynia cordata.
The volatile oil was extracted from H. cordata by water stream distillation method, and analyzed by GC coupled with FID.
12 bathes of samples collected from different regions were analyzed; the GC fingerprint of the volatile oil of H. cordata was subsequently established.
The established GC fingerprint can be used for the identification of H. cordata.
