Abstract: In this paper,we reviewed the research progress of the chemical constituents of Camellia oleifera Abel.and its antitumor activity.The main chemical constituents are triterpenoids and triterpenoid saponins,flavonoids,fatty acids,steroids and lignans in Camellia oleifera Abel..The triterpenoids and triterpenoid saponins are the most abundant chemical constituents in Camellia oleifera Abel..The main inhibitory activities of tumor cells were oleifera saponin B1,B2,C1,C2 and camellia saponin B.Polysaccharide,camellia saponin A and B can inhibit the tumor xenograft.The anti-tumor mechanism needs to be further studied.

Key words: Camellia oleifera Abel., chemical constituents, antitumor activity
