인삼엽차 제조를 위한 연구의 일환으로 인삼엽의 성숙시기인 7, 8, 9월 중에 인삼엽을 각각 채엽하여 사포닌 함량 및 조성을 비교, 분석한 결과는 다음과 같다. 1. 인삼엽의 사포닌함량은 7월엽이 17.17%, 8월엽이 16.67%, 9월엽 15.58%로서 채엽시기가 늦어질수록 감소하였으나 ginsenoside pattern은 유사하였다. 2. 인삼엽의 ginsenoside 함량 및 조성은 채엽시기와 관계없이 ginsenosides-Re, -Rd, -Rg_1 등이 총사포닌 성분의 70% 이상을 차지하였고 그 다음으로 -Rb_1, -Rb_2, -Rc 순이었으며 protopanaxadio계 사포닌은 8월엽, protopanaxtriol계 사포닌은 9월엽에서 가장 높은 함량을 나타내었다. 3. 인삼엽의 채엽시기별 protopanaxadiol(PD) / protopanaxatriol(PT)계 사포닌의 함유비율은 7월엽의 1.13에서 9월엽은 0.85로 점차 낮아지는 경향을 나타내었다.
To study of production of Panax ginseng leaf tea, after harvested the leaves in July, August, and September as ripening season, the content and composition of ginseng saponin were investigated. 1. Crude saponin contents in the leaves were about 16.5%, and they were found to be lower in the leaf harvested in September than those harvested in July or August. 2. As similar patterns were observed with month to month in ginsenoside, sum of major ginsenosides of -Re, -Rd and -Rg_1 was fixed about 70% of saponin at harvested in each month. And minor components were ginsenoside -Rb_1, -Rb_2 and -Rc as in order. 3. The ratio of protopanaxadiol(PD) / protopanaxatriol(PT) was revealed reduction of 1.13 of harvested in July to 0.85 of those in September gradually. The contents of protopanaxadiol were high in the leaves of August and protopanaxatriol was high in those of September.
