Abstract
Caesalpinia sappan L. (Leguminosae) is an oriental medicinal herb distributed in China and Taiwan, and its heartwood has been traditionally used as an analgesic, a therapy for thrombosis or tumor. This study was to investigate the proliferation and inhibition effects of Caesalpinia sappan extracts against human epithelial cell and cancer cell lines. The methanol extract of dried C. sappan heartwood was evaporated (KS-6), and then sequentially extracted by hexane (KS-01), chloroform (KS-02), ethyl acetate (KS-03), n-butanol (KS-04), and water (KS-05). After 48 hr of exposure, these fractions at a concentration of 50 ¥ìg/ml significantly increased, and reduced cell proliferation in both human normal epithelial and cancer cell lines. The ethyl acetate fraction (KS-03) among organic solvent fractions was 120.2% of the most proliferation activity (50 ¥ìg/ml) against HaCaT human epithelial cell. However, fractions from chloroform, butanolic and methanolic extract had 7.2, 28.7 and 20.8% of antiproliferative effect on HaCaT cell, respectively. In cell proliferation effects of C. sappan extract on HeLa, SiHa and C33A human cervical cancer cells, chloroform fraction (KS-2) was the most antiproliferative activity, its antiproliferative rate (dosage, 50 ¥ìg/ml) relative to control was 25.8, 12.2 and 17.4% for SiHa, HeLa and C33A, respectively. The results indicated that the six extract fractions could induce cell cycle stimulate or arrest in some way. Finally, further investigation is needed to assess the molecular mechanisms mediated anticancer activities of this plant.
