Objective To study the chemical constituents from Medicated Leaven (namely Massa Medicata Fermentata in Chinese). Methods Compounds were isolated and purified from chloroform extract of Medicated Leaven by column chromatograph of silica gel, ODS, Sephadex LH-20, HPLC, and their structure were elucidated on the basis of spectral data and physicochemical property. Results Eleven chemical compounds were identified as 5-pentacosyl resorcinol (1), 5-heptadecyl resorcinol (2), 5-heneicosyl resorcinol (3), 5-tricosyl resorcinol (4), (9S,10E,12Z)-9-hydroxy-10,12-octadeca-dienoic acid (5), trans-4-hydroxy-2-nonenoic acid (6), 9,10,11-trihydroxy-11(E)-octadecenoic acid (7), (9S,12R,13S)-9,12,13-trihydroxy-10(E)-octadecenoic acid (8), (9S,12S,13S)-9,12,13-trihydroxy-10(E)-octadecenoic acid (9), (9S,12S,13S)-9,12,13-trihydroxy-10(E)-octadecenoic acid methyl ester (10), and 9,12(Z)-octadecadienoic acid methyl ester (11). Conclusion All above compounds are all isolated from Massa Medicata Fermentata for the first time, and the chloroform extract of Massa Medicata Fermentata and compound 8 showed inhibitory effect against TNF-α generation of RAW 264.7 induced by LPS in a dose-dependent manner.
