摘　　要：石蒜属植物为具有地下鳞茎的多年生草本植物．有重要的药用价值，全属植物约有20余种。我国有石蒜属植物约15种，集中分布于长江中下游地区，野生资源比较丰富。忽地笑（Lycorisaurea Herb．）是石蒜属植物在我国分布较广泛的一种。加兰他敏（Galanthamine）等生物碱是石蒜属植物中主要的药用成分。Using laser confocal microscopical techniques, we observed the anatomical structure of mature root, bulb, and leaf of Lycoris aurea Herb., and also did some research on the localization of galanthamine in the above-mentioned vegetative organ. The results are as follows： In the mature root, the galanthamine distributes mainly in cell wall, especially in cell wall of exodermis and endodermis and vessel wall. In the mature leaf, galanthamine exist in cell wall of vascular bundle, mesophyll cell between vascular bundles and epidermis cells. The scale leaf is the essential accumulational organ. Plenty of galanthamine distribute in the adaxial parenchyma cell, epidermis cell wall, and also in the clingy cell of abaxial epidermis cell.
