Abstract

Paeoniae radix has been considered as one of the most important crude drugs used in traditional oriental medicine and has been employed as a circulatory tonic in care of weakness, night sweats, and lumbar pain, etc. Platelet activation plays an important role in thrombosis and haemostasis. Active compounds for the inhibition of platelet activation from Paeoniae radix were extracted and fractionated into five fractions. Its fraction two and three of ethyl acetate extract inhibited the aggregation of washed rabbit platelets induced by collagen. Two active compounds, bezoyloxypaeoniflorin and paeoniflorin, were isolated from fraction two and three by silica gel column and high performance liquid chromatography. The chemical structures were determined by comparison of their proton and carbon nuclear magnetic resonance spectra. Benzoyloxypaeoniflorin showed strong inhibition at the concentration of 100 ug/mL against collagen-induced washed rabbit platelets aggregation. It is suggested that Paeoniae radix has become food material to prevent a cardiovascular disease.

최근 동물성 식품 및 지방 섭취 증가로 인한 현대인의 식생활 변화로 혈소판 활성화가 직접적 원인인 뇌심혈관질환의 사망률이 증가되고 성인병 예방과 치료의 대처방안으로 식품의 기능성에 대한 관심이 높아짐에 따라 진경, 항균, 진통, 해열, 이뇨, 지한, 진정 등의 작용을 갖는 작약(Peoniae radix)으로부터 추출, 분리.정제한 분획물에서 혈소판 응집 억제 작용이 있는 생리활성물질을 분리.동정하였다. 작약에서 methanol, ethyl acetate의 용매추출과 이러한 추출물에서 컬럼 및 HPLC로 분리.정제한 2개 물질의 화학구조를 $^1$H-과 $^{13}$C-NMR 스펙트라 분석한 결과 benzoyloxypaeoniflorin과 paeoniflorin을 확인하였고 혈소판 응집 억제작용은 benzoyl-oxypaeoniflorin이 비교적 강하게 나타내었다.
