Four polyacetylene compounds, heptadeca-1,9-dien-4,6-diyn-3-ol (A-1), heptadeca-1-en-4,6-diyn-9,10-epoxy-3-ol(B-1), heptadeca-1,8-dien-4,6-diyn-3,10-diol (C-1) and heptadeca-1,16-dien-4,6-diyn-9,10-epoxy-3-ol, were isolated from Panax ginseng C. A. Meyer and identified by various spectral data.
Epoxy groups in B-1 and D-1 polyacetylene compounds were hydrolyzed to yield corresponding diols.
When A-1, B-1, D-1 polyacetylene compounds were irradiated with 300 nm UV light, allylic hydroxyl groups were oxidized to carbonyl group yielding heptadeca-1,9-dien-4,6-diyn-3-one, heptadeca-1-en-4,6-diyn-9,10-epoxy-3-one and heptadeca-1,16-dien-4,6-diyn-9,10-epoxy-3-one.
Polyacetylene B-1 and D-1 compounds were synthesized and identified by various spectral data. The spectral data of synthesized and natural polyacetylenes were in good agreement.
한국산 인삼으로부터 네 개의 주요 폴리아세틸렌 화합물을 분리하였다. 분리된 폴리아세틸렌의 구조는 heptadeca-1,9-dien-4,6-diyn-3-ol (A-1),heptadeca-1-en-4,6-diyn-9,10-epoxy-3-ol (B-1),heptadeca-1,8-dien-4,6-diyn-3,10-diol (C-1)과 heptadeca-1,16-dien-4,6-diyn-9,10-epoxy-3-ol (D-1)임이 여러가지 분광학적인 자료를 통해서 확인되었다.
에폭시기가 산촉매하에서 다이올로 바뀐다는 사실로부터 분리된 폴리아세틸렌에는 에폭시기가 존재함을 확인할 수 있었다.
이러한 폴리아세틸렌 화합물에 300nm의 자외선을 조사시킨 결과 산화생성물인 en-on-diyne의 발색단을 가진 폴리아세틸렌 화합물을 얻었다.
Heptadeca-1-en-4,6-diyn-9,10-epoxy-3-ol (B-1)과 heptadeca-1,16-dien-4,6-diyn-9,10-epoxy-3-ol (D-1) 화합물을 합성하여 확인하였다.
