Comparison of The Components and the Contents in the Roots of Veronicastrum -sibiricum and Veronicastrum sibiricum var. zuccarini by HPLC-

Veronicastrum속 식물의 성분에 관한 연구 -HPLC를 이용한 냉초와 털냉초의 성분 및 함량 비교-

Veronicastrum species are perennial herb growing on the moisty land. They involves on species (V. sibiricum, Naeng-Cho), one subspecies (V. sibiricum var. zuccarini, Tuel-Naeng-Cho) and one variety (V. sibiricum var. zuccarini for. albiflora). This paper deals with a comparison of the chemical components between Naeng-Cho and Tuel-Naeng-Cho.) In the specified HPLC condition used with ${\mu}BondapakC_{18}\;column$, the retention time of aucubin, catalpol, minecoside and veratryl catalpol ester were 2.30, 2.65, 3.05 and 3.10 min, respectively, and in the other condition used with ${\mu}Bondapak\;C_8-NH_2$, the retention time of aucubin, catalpol, minecoside and veratryl catalpol were 5.4, 5.4, 4.4 and 3.2 min, respectively. The contents of minecoside in Tuel-Naeng-Cho were found to be 3.5 and 1mg/g of dry plant material and that of catalpol were found to be 5 and 2 mg/g, respectively.
