2 opea is one the main genus of Dipterocarpaceae, consisting of approximately 100 species and widely distributed in Indonesia specially in Kalimantan The local name is cengal, merawan hitam or pengarawan. The plant ussually can be used as material building, plywood etc. This family of plant is known to produce a variety of resveratrol oligomer These structures are very interesting and showed interesting biological activity, such as antibacterial, anticancer, antihepatotoxic, and anti-iv

19 Conclusion This research we concluded that resveratrol derivative isolated from the stem bark of opea consist of dimer, trimer, and tetramer resveratrol. Some compounds have biological activity as antioxidant and cytotoxic effect against Raji and ela-s3 lines cell. opeaphenol showed the highest activity as antioxidant. Whereas ampelopsin and vaticanol B gives the highest cytotoxic effect against ela-s3 and Raji.
