Abstract

Two known flavonoids, luteolin (1) and acacetin (2) were isolated from a $CHCI_3$ soluble fraction of the whole plants of Chrysanthemum zawadskii Herbich var. latilobum Kitamura, and their structures were determined by NMR analysis. The luteolin (1) was isolated from this plant for the first time. These compounds were examined for their in vitro cytotoxic activities against four human cancer cell lines including HCT116 (colon), UO-31 (renal), PC-3 (prostate) and A549 (lung) by sulforhodamine B(SRB) assay. Acacetin (2) showed significant cytotoxic activity against HCT116 and UO-31 cells with an $IC_{50}$ of 2.44 and $2.89\;{\mu}g/ml$, respectively.

구절초 전초의 chloroform 분획물로부터 2종의 flavonoid화합물을 분리하여 NMR을 통해서 구조를 확인한 결과, luteolin (1)과 acacetin (2)으로 구조 동정되었다. 이들의 화합물 중에서 luteolin (1)은 구절초에서 처음으로 분리하였다. 분리된 화합물은 sulforhodamine B (SRB) assay법에 따라 인체암세포주인, HCT116 (결장암) , UO-31 (신장암), PC-3 (전립선암) 와 A549 (폐암)등에 대한 in vitro에서의 세포독성을 실험하였다. 그 결과, acacetin (2)이 HCT116 $(IC_{50}\;2.44\;{\mu}g/ml)$과 UO-31 $(IC_{50}\;2.89\;{\mu}g/ml)$에서 유의할만한 세포독성을 나타내었다.
