Preparation and Chemical Analysis of Volatile Oil in Two Different leaf type of Ficus hirta Vahl

To analyze the chemical constituents of volatile oil in two different leaf types of Ficus hirta Vahl. Steam distillation was used to collect the different leaf types of Ficus hirta Vahl., the volatile chemical components of extracts were analyzed using GC-MS,and the relative contents of various chemical components in the volatile oils of the two medicinal materials were calculated by area normalization method. The volatile oils of the Ficus hirta Vahl of three-lobed leaf type and five-lobed leaf type contained 38 and 39 compounds, respectively. The main components are coumarins, organic acids, aldehydes, esters, alcohols, etc. In addition, there are some Hydrocarbons, phenols, ketones, and the chemical composition and relative content of volatile oils of the two have large differences.The method can quickly and easily identify the chemical constituents of the volatile oils of two different leaf Ficus hirta Vahl., and there are significant differences in the chemical constituents in the volatile oils of the Ficus hirta Vahl. of three-lobed leaf type and five-lobed leaf type.
