In this study, extracts from the heartwood of black locust (Robinia pseudoacacia L.) were obtained with ethanol solvent before and after extraction with n-hexane. Chemical composition were analyzed and compared by GC-MS. The results showed that the major components in the heartwood ethanol extract before extraction with n-hexane solvent to be the (23S)-ethylcholest-5-en-3.beta.-ol (18.33%), while the major heartwood ethanol extracts constituents after extraction with n-hexane solvent was resorcinol (51.96%). The same components of the heartwood ethanol extracts before and after extraction with n-hexane solvent also contained amounts of the Hexadecanoic acid and 9,12-Octadecadienoic acid (Z,Z)-. The other main components of the ethanol extract mainly contained about 13.75% stigmasterol, 9.35% 9,19- Cyclolanostan-3-ol, 24-methylene-, (3.beta.)-, 7.11% Lup-20(29)-en-3- one, 6.27% 9,12,15-Octadecatrien-1- ol, (Z,Z,Z)-, 6.06% Hexadecanoic acid 4.54% Ergost-5-en-3-ol, (3.beta.)-, and 3.53% campesterol.
