The research was investigated to collect basic data in order to consumption expansion and processed product of Erythronium japonicum. Leaves of Allium japonicum were divided into 17 kinds of amino acid and 38 kinds of free amino acid. Total content of amino acid and free amino acid showed 2,342 mg･100g-1 and 225 mg･100g-1, respectively. Reducing DPPH radical scanvenging half, quantity (IC50 value) of Erythronium japonicum. extraxt 1,000 mg･L-1 were showed the methanol extract (30.8 mg･L-1), ethanol extract (34.1 mg･L-1), hot water extraction water (47.5 mg･L-1). Nitrite scavenging activity in 1,000mg･L-1 of Erythronium japonicum leaf extraxt was followed the ethanol extract (75.0%), methanol extract (74.1%), hot water extraction water (70.3%), respectively. Methannol extract of Erythronium japonicum leaf at 400mg･L-1 inhibited over 99% lung cancer cell (Calu-6), breast cancer cell (NCF-7) and colon cancer cells (HCT-116). Likewise, investigated data will be utilized basic material, and intake of Erythronium japonicum will be enhancing physiological activity, and will be considered to prevent and remedy to lung cancer, breast cancer and colon cancer.

We have studied the effects of dampening papers (Dampened paper, Newspaper, Korean paper, Flower sheet), silica gel (30g, 60g) and temperature (20℃, 25℃) on color changes of Erythronium japonicum. In the treatment of 20℃, color changes were low in treatments with silica gel rather than in a treatment of dampening papers. In particular, newspaper and Korean paper showed much less changes in colors by the combination treatments with 30g of silica gel. Likewise, in the treatment of 25℃, color changes were low in combination treatments with silica gel rather than in a alone treatment of dampening papers. For the combination treatment with 30g of silica gel, low color changes were shown in the divisions of newspaper and Korean paper, while for the combination treatment with 60g of silica gel, low color changes were shown in the those of Korean paper and dampened paper.

어린잎을 식용으로 하고 전초를 차전엽산자고라 하여 강장약 및 진해제로 사용되는 얼레지(Ery-thronium japonicum)의 잎의 성분 연구에 착수하여 phtalate ester인 di -0-n-decylphthalate,fla-vonol인 kaempferol 및 quercetin, 그리고 그들의glucoside인 astragalin및 isoquercitrin의 구조를 동정하였다.
