Abstract

Echinacea is a North American native medicinal herb used traditionally for wounds, burns, snake or insect bites, colds, infections, and inflammation by indigenous Americans. We investigated the effects of the root and stem of fresh Korean-grown Echinacea angustifolia methanol extracts and fractionation extracts on the cytotoxicity against cancer cells (HL60, 3LL). The extracts were prepared by step-wise fractionation of methanol extracts of Echinacea angustifolia using hexane, chloroform, ethyl acetate, buthanol, and water. From the tests, root and stem parts of Echinacea showed the cytotoxic effect on cancer cells. The cytotoxie rate of the ethyl acetate fraction of the root parts showed 79% against HL60 cells at low concentration (0.125 mg/mL), and hexane fraction of the root and stem parts gradually increased as the concentration of samples increased, and the root parts showed 82% at 1.0 mg/mL concentration against HL60 cells, chloroform fraction of the root part showed 78.4% against HL60 cells and 68.4% on 3LL cells at 1.0 mg/mL concentration, water and butanol fraction of these results, it is considered that ethyl acetate fraction of the root and stem parts showed 60.1% to 77.1% against HL60 cells, after testing by MTT assay system. From these results, it is considered that ethyl acetate fraction of the Echinacea angustifolia root parts has stronger anticancer effects than any other fractions in vitro.

Echinacea angustifolia의 줄기와 뿌리 methanol 추출물과 용매별 분획물의 인간유래 백혈암세포인 HL60과 폐암세포인 3LL 세포를 대상으로 항암 활성을 검색한 결과는 다음과 같다. HL60 세포의 경우에 뿌리 추출물은 저농도(0.125 mg/mL)에서 ethylacetate, acqueous, buthanol 분획물의 순으로 $77%{\sim}72%$의 세포독성효과를 나타내었고, hexane 분획물이 저농도에서는 독성효과가 낮았으나 점진적으로 독성효과가 커짐(1.0 mg/mL, 82%)을 알 수 있었다. 3LL 세포주에 대해서는 뿌리의 경우 저농도(0.25 mg/mL)에서 buthanol, ethylacetate 분획물이 $43.5%{\sim}26.3%$의 낮은 세포독성효과를 나타내었고, 1.0 mg/mL 농도에서는 chloroform, hexane 분획물이 $68.4%{\sim}58.5%$의 세포독성을 나타내었다. 에키네시아의 줄기보다 뿌리의 세포독성이 컸고, HL60이 3LL보다 세포독성이 크게 나타났다.
