One hundred and forty-four extracts have been tested for the presence of saponins, using the method of froth formation, precipitate formation by acid hydrolysis, Liebermann-Buchard reaction on the acid hydrolysate, and hemolytic activity of the extracts. Among the samples tested, thirteen extracts showed positive saponin reaction in all the tests employed and one hundred and thirty-six showed positive in one or more tests of saponins. The results are tabulated.

The seasonal variations in the contents of ginseng components were analyzed with the samples harvested from April to October. The contents of soluble components such as sugars, amino acids, terpenoid and total methanol extract, increased gradually from April to July and remained almost constant from July to October. Therefore the quality of ginseng harvested at July will not be expected to be significantly different with that of October.

한국인삼의 노화방지 효과를 입증하는 의도에서 인삼의 항산화활성을 다루었다. 인삼 또는 그 유효성분을 추출하여 마우스에 투여하면 알코홀 투여로 인하여 상승되는 지질 과산화물의 함량을 감소시켜주었으며 그 유효성분의 화학구조를 결정한 결과 3-hydroxy-2-methyl-$\gamma$-Pyrone (maltol)임을 밝혔다. This paper is concerned with the studies on the effective components possessing antioxidant activity, with a view to demonstrate the anti-aging activity of Korean ginseng. Feeding the extract of Korean ginseng or its effective component to mice inhibited strongly the lipid peroxidation induced by ethanol intoxication. From the extract of Korean red ginseng, one effective component, Compound A, mp. $143^{\circ}$, $C_6H_6O_3$, was isolated by chromatographic purification and its chemical structure was determined as 3-hydroxy-2-methyl-$\gamma$-pyrone (maltol).
