Growth Factors Affecting to Kalosaponins Contents of Kalopanax pictus Nakai

한국산 음나무의 Kalosaponins 함량과 이에 영향하는 몇 가지 생장요인

  • Published : 2002.09.01

Abstract

Four kinds of kalosaponins from inner bark of Kalopanax pictus Nakai as a medicinal and edible timber tree species growing in Korea was analyzed by HPLC. A considerable range of variation in the contents was observed among population. The kalosaponins contents in inner bark from each population were the highest in the Mt. Barwang (30.37 mg/g on the dry weight basis) followed by Mt. Gariwang, Hanra II, Mangun, Paltan, and Hanra II population. Growth factors that might have influenced the contents of the kalosaponins were also examined. As both analysis results of partial correlation and multiple regression, the weight of inner bark and tree age were influenced the kalosaponin O contents. The kalosaponin B contents was influenced by both the weight of inner layer bark and annual mean DBH increment. The contents of kalosaponins appeared to be closely related to the inner bark characteristics.

국내에 분포하는 음나무 (Kalopanax pictus Nakai) 자생군락에서 7집단 197본을 선정하여 생리활성물질인 kalosaponins 함량을 HPLC로 분석하였다. 또한 kalosaponins 고함유 개체를 대상으로 이들 개체의 생장특성을 조사하여 단순상관, 편상관 및 다중회귀분석을 통해 kalosaponins 생산에 영향을 미치는 생장요인을 추정하였다. 자생집단별 내피의 총kalosaponins 함량은 발왕산집단 (30.37 mg/g dry weight)으로 가장 높았고, 가리왕산 집단, 한라산 II집단, 전남 망운집단, 경기 팔탄집단, 한라산 I집단 순이었다. Kalosaponins 함량과 생장특성에 대한 분석결과, kalosaponin P 함량에 가장 높게 영향하는 인자는 내피두께로 나타났으며, kalosaponin O 함량은 내피무게와 수령으로 나타났으며, kalosaponin B 함량은 내피중량과 평균흉고직경으로 나타났다. 이상의 결과로 보아 음나무 내피의 특성이 kalosaponins 생산에 밀접하게 관계하는 것으로 나타났다.
