leaf and stem of Leonurus japonicas from Guizhou were analyzed by Fourier transform infrared spectroscopy and solid phase microextraction coupled with gas chromatography-mass (SPME-GC-MS) for the understanding and application of L. japonicas from Guizhou. Method: The detectable components with over 80% matching were statistically analyzed using the peak area normalizatilon method. Result: The detectable component in flower
leaf and stem of Leonurus japonicas from Guizhou was 43
27 and 29
respectively
and 16 volatile components were found to be contained in all samples. Furthermore
volatile components in flower
leaf and stem of L. japonicas from Guizhou were much different from those reported in literatures. The most remarked result found by comparing the main volatile components (content>3%) contained in flower
leaf and stem was that their relative content (such as trans-caryophyllene
6
10
14-trimethyl-2-pentadecanone
β-cubebene
α-humulene and caryophyllene oxide
et al.) are much variant from each another although most of the main volatile components are found in all of samples:the flower has the highest content of trans-caryophyllene (38.9%) and the amount of α-humulene in flowers are nearly double of leaf and stem; the content of β-cubebene and caryophyllene oxide in leaf are nearly twice of flowers and stems. Conclusion: Terpenoids is the most high in volatile components of L. japonicas from Guizhou
and the content of trans-caryophyllene is first in different parts.
