| The volatile oil from the root, stem, leaf and seed in Ardisia japonica (Hornsted) BL. was extracted by steam distillation
method, relatively. The constituents and their contents of the oil from different parts were tested and analyzed by means of capillary gas chromatography and combined gas chromatography-mass spectrometry. The results showed that there were 79 components were identified from A. japonica, and the four same components were detected from 4 different parts of A. japonica. The contents of the same components accounted for 62.59%, 70.15%, 47.71%, 45.62% of the root, stem, leaf and seed overall volatile oils repectively. The results demonstrated that the most component from the 4 different parts was only the α-Caryophyllene, and arrangement in content of the component order was stem>root>leaf>seed. The second component stored in root, stem and leaf was Caryophyllene, stored in seed was g-caryophyllen, and it was the most different among seed oil and another 3 parts oil. In a word, this research could provide a foundation for utilization in A. japonica. |
