Abstract:

In order to avoid the great resource waste due to the discard of Santalum album L. leaves, the Py-GC/ MS was employed to analyze the extractives from Santalum album L. leaves. The results indicate that there are 118 compounds in the benzene/ethanol extraetives from Santalum album L. leaves, including 16-hentriacontanone （8.69%）, 11, 14, 17-eicosatrienoic acid methyl ester （ 8.49% ）, hexadecanoie acid （ 5.38% ）, pyrazine （4.01%）, eyclooctacosane （3.89%）, phenol （3.19%）, etc. , and that there are 48 compounds in the acetone extractives, including lupan-3-ketone （ 39.35% ） , taraxasterol （7.60%） , β-sitosterol （5.38%） , taraxerol （3.42%）, acetaldehyde （2.37%） and androstan-6-ketone-（5α） （2.36%）, etc. It is thus concluded that the extraetives from Santalum album L. leaves contain rare medicinal materials and rare spices, and that the extraction by-products can be used as not only top-grade cosmetics but also biological energy.
