Sorbus Cortex를 실리카겔 칼럼크로마토그래피하여 lupane계 triterpenoids인 lupenone과 lupeol을 분리, 분광학적 방법으로 화학적 구조를 확인한 후 그 화합물들을 3종의 Sorbus Cortex에 대한 정량분석 표준품으로 이용하였다. Lupenone과 lupeol은 VA-5MS[(5%-phenyl)methylpolysiloxane, $30m{\times}0.25mm$, $0.25{\mu}m$] 칼럼으로 기체크로마토그래피법으로 분석하였으며 lupenone과 lupeol의 함량은 시료의 종류에 관계없이 각각 0.050~0.056%와 0.772~0.834%로 나타났다.

Lupenone and lupeol, the triterpenoids of Sorbus Cortex, were isolated with silica gel column chromatography and used as the standard substances for the quantitative analysis. The compounds were identified with IR, NMR, EI-MS. They were separated on VA-5MS [(5%-phenyl)methylpolysiloxane, $30m{\times}0.25mm$, $0.25{\mu}m$] column by gas-chromatograph. The contents of lupeone and lupeol in three different samples of Sorbus Cortex were in the range of 0.050~0.056% and 0.772~0.834%, respectively.
