두릅나무 Aralia elata순의 saponin을 분리하여 조사한 결과는 다음과 같다. 1. Saponin의 함량과 종류는 자연산이 온상산보다 많고, 가열에 의해서는 모두 감소하였으며, 잎이 자랄수록 그 함량은 증가하였다. 자연산 날것 식용적기(Nr2)의 총 saponin 종류는 37개였다. 2. 자연산의 saponin 패턴은 생육시기에 따라 변하였으며 날것 식용적기(Nr2)가 다른 것에 비해서 크게 달랐다. 그러나 가열 처리한 결과는 saponin 패턴이 변화되어 시기적 차가 줄었다. 온상산은 자연산에 비해 피크가 단순하고 시기별 차이는 적었지만 가열에 의한 패턴의 차도 적었다. 3. 자연산 날것 식용적기는 ‘b’ saponin이 특이하게 많았고 나머지에서는 ‘d’ saponin이 가장 많았다.
We extracted and analysed the saponin fraction in the shoot of Aralia Elata. The results were as follows. 1. Natural samples had higher contents and more kinds of saponin than those grown in the green-house. The contents and the kinds of saponin decreased by steam treatment in both samples while the contents increased with the growth. The number of saponins in the natural raw sample (Nr2) which was at the most suitable stage for use was 37. 2. The saponin pattern of Nr2, with the large Fh saponin was specifically different from those with different harvest time which had large ‘d’ fraction. But all the natural samples which were steam-treated showed similar saponin patterns irrespective of harvest time. The saponin patterns of the green-house grown samples were simpler and showed less change during growing compared with those of the natural ones. All the steamed green-house grown samples showed the similar saponin patterns.
