Abstract
Camellia oil trees are widely found at low-midde elevations in Taiwan. Their seed can produce high-grade edible oil. While at the same time, they also produce lots of seed residue, related utilization and research information are relative limited. In order to broaden the utilization of seed residue, the goal for this project is to screen antimicrobial compounds from seed residue. Main methods includes seed residue extracted with methanol, liquid-liquid partition of the methanol crudes to different fractions, bioactivity screening tests, etc. The results give a sketch of bioactivity activeties of seed residue, it may also contribute to offer more data and multiple utilization to the endemic tree.
