남부지방에 서식하는 식물체 중에서 꽃기린, 민들레, 박주가리, 후박나무, 팔손이 나무, 달맞이꽃, 동백나무 그리고 유동나무를 대상으로 약용성분의 일부분을 차지하고 있는 saponins 및 alkaloids의 검색을 실시한 결과를 요약하면, 1. Crude saponins 함량 중, crude 인삼 saponins 함량은 달맞이꽃이 가장 높았으며, crude saikosaponins 함량은 박주가리에서 가장 높게 나타났다. 2. Crude alkaloids 함량은 박주가리에서 가장 높게 나타났다. 3. Saponins 획분에 대해 HPLC분석을 실시한 결과, 꽃기린, 민들레 그리고 박주가리에는 인삼 saponin태 물질, 후박나무, 팔손이나무 그리고 달맞이꽃에는 인삼 saponin태 물질과 saikosaponin c태 물질, 동백나무와 유동나무에는 saikosaponin c태 물질의 존재가 추측되었다. 4. Alkaloids 획분에 대해 GC분석을 실시한 결과, 팔손이나무에서만 nicotine태 물질의 존재가 추측되었다.
This research was conducted to determine contents of saponins and alkloids for plants distributed in the sourthern region of Korea. The extracts from each plants were purified by solvent fractionation, column chromatography, TLC and analyzed GC and HPLC. As a result, contents crude gingseng saponins and saikosaponins were the highest in Oenothera odorata and Metaplexis japonica, respectively. and contents crude alkaloids was the highest in Metaplexis japonica among the all plants xamined. HPLC was conducted to detect of saponins. As a result, ginseng saponin-like substances was detected in the extracts of Euphobia splendens, Taraxacum mongolicum and Metaplexis japonica, gingsen-like substances and its of saikosaponin c-like substances was detected in the extracts of Camellia japonica and Aleurites fordii. GC was conducted to detect of alkaloid. As a result, nicotine-like substances was detected in only the extracts of Fatsia japonica.
