와송의 생리활성을 증대시킬 수 있는 복합물을 제조하기 위하여 와송 추출물, 한약재(백복령, 창출 및 사인)의 혼합물 및 한약재와 와송의 복합물(1:1, PMO-1; 1:3, PMO-3)의 항산화 및 암세포 생육 저해능을 비교하였다. 총 페놀 및 플라보노이드 함량은 한약재 혼합물이 와송 추출물보다 많았으며, 와송 복합물에서는 PMO-1이 PMO-3보다 더 높았다. 라디칼 소거능, 환원력 및 아질산염 소거능은 PMO-1이 PMO-3보다 활성이 높았으며, tyrosinase 활성 저해능 및 MCF-7 및 HT-29 세포의 생육 저해능은 와송의 함유량이 많은 PMO-3의 활성이 더 높았다. 따라서 모든 생리활성시험에서 와송 복합물이 와송 추출물이나 한약재 혼합물에 비해 유의적으로 활성이 높았으며, 와송 복합물은 와송 추출물의 생리활성의 상승에 효과적일 것으로 예상된다.
This study was carried out to determine the biological activities of Wa-song (Orostachys japonicus) hot water extracts. Four types of extract samples were prepared, including Wa-song, traditional plants mixture [PM; mixture of Baekbokryung (Poria cocos), Changchul (Atractylodis rhizoma), and Sa-in (Amomum xanthoides)], and two different ratio composites of these (mixture of PM and Wa-song extract, 1:1 (v/v); PMO-1 and 1:3 (v/v); PMO-3). Their biological activities were measured using various in vitro assays. Total phenolic and flavonoid contents of PM were higher compared to those of Wa-song, and those of PMO-1 were higher than those of PMO-3. Further, PMO-1 contained higher ABTS and DPPH radical scavenging, reducing power, and nitrite scavenging activities than PMO-3. On the contrary, PMO-3 contained higher tyrosinase and inhibitory activities of MCF-7 and HT-29 cancer cells than PMO-1. According to the results, biological activities of PMOs were significantly higher than those of Wa-song extract and PM in in vitro assays. Therefore, we expect that PMOs could show higher biological activities than Wa-song extract alone in vivo.
