[The localization of galanthamine in vegetative organ of Lycoris aurea Herb].

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.
