碩士 === 輔英科技大學 === 保健營養系碩士班 === 104 === Cinnamomum macrostemon Hayata Miq.(Lauraceae) is a medium-sizedever green tree, grown in Taiwan. The chemical constituents and the biological activity of this plant have notyet been identified. In continuation of a program toward the studies of chemotaxonomy from Formosan Lauraceous plants. Investigation on the MeOH extract of the stem of this species has led to the isolation including coumarin (1), scopoletin (2), aesculetin dimethyl ester (3), isoobtusilactone A (4), β-sitostenone (5), β-sitosterol (6), stigmastenone (7), stigmasterol (8) and palmitic acid (9). On antioxidant capacity, scopoletin (2), aesculetin dimethyl ester (3),isoobtusilactone A (4), β-sitostenone (5) have no significant differences on radical scavenging. Scopoletin (2) showed inhibition of A549 on antipro-liferative effects.
