Studies on the Development of Anticarcinomatous Resources -Chemical constituents of the root of Aster divaricatus L. (II)-

항암성자원생약개발(抗癌性資源生藥開發)에 관(關)한 연구(硏究) -미국산 개미취근(根)의 성분연구(成分硏究)(II)-

We had previously reported that five compounds were obtained from fraction A of Aster divaricatus by using column chromatography and presumed them to be alkanes $CH_3\;(CH_2)n\;CH_3.$ In this investigation, compound (II) out of above five compounds was identified as hydrocarbon $C_{16}H_{34},$ m.w. 258 belonging to alkane, by using nmr spectra, mass spectra and the elementary analysis. It was also found that compound (IV) is the same compound as the campound (II).
