Objective: To analyze and identify fatty acids in the seeds of Sterculia lychnophora.
Method: The compositions was isolated and determined by GC-MS technique, and area normalization method was used to make quantitative analyze of the content of compositions.
Results: 21 Fatty acids and 5 other compositions were isolated and determined.
Conclusion: The major fatty acids are 9,12(Z,Z)-octadecadienoic acid(37.96%), hexadecanoic acid(24.77%), 9-(Z)-octadecenoic acid(19.77%) and octadecanoic acid(5.01%).
