Objective: To study the chemical constituents of Yunnan propolis in which the nectar source is rape. Methods: A variety of chromatographic methods were used to extract and separate compounds. The structures of compounds were identified by physicochemical constants and spectral analysis. Results: Twenty chemical constituents were isolated from Yunnan propolis and identified as follows: chrysin (1), apigenin (2), teakwoodin (3), galangin (4) Methoxy galangin (7), isorhamnetin (8), 3,7-dimethoxyquercetin (9), 3,3 Dimethoxy quercetin (10), sophoronin (11), pinotrophin (12), 5-methoxyhirtuin (13), 3- (15), isoferulic acid (16), 3,4-dimethoxycinnamic acid (17), stearic acid (18), octacosanol (19), triacontanol (20) . Conclusion: Among them, compounds 5, 6, 8-10, 13-17 are isolated from Yunnan propolis for the first time.
