TRITERPENE GLYCOSEDES OF Hedera canariensis. I. STRUCTURES OF GLYCOSIDES L-A, L-B_1 L-B_2, L-C, L-D, L-E_l, L-G_2, L-G_2, L-G_3, L-G_4, L-Hj, L-H_2, AND L-Ij FROM THE LEAVES OF Hedera canariensis

摘要

The aim of the present series of investigations is a systematic study of the glycoside compositions of various organs of Hedera canariensis Willd. (synonyms Hedera helix canariensis DC, H. algeriensis Hibberd, H. maderensis C. Koch, H, grandifolia Hibberd, H. azorica Carr., and H. canariensis var. azorica Bean), fam. Araliaceae. Algerian ivy is distributed in the Azores, the Canary islands, the islands of Madeira, and parts of the West African littoral (Algeria, Morocco) and is widely cultivated as a decorative plant in many countries [1]. However, its glycoside composition has not been studied previously.
