Natural Products Isolated from Plants of the Canary Islands

Abstract

This work reports the results obtained from investigations on the natural products of 129 plants. 105 of them are endemic to the Canary Isles; 14 are not endemic but widely distributed over the whole archipelago; 5 (Senecio petasitis D.C., Asparagus plumosus Baker, Asparagus tenuissimus (Hort.) Kudo, Sansevieria trifasciata Prain., and Yucca gloriosa L.) are intensively cultivated as ornamental plants; the remaining 5 (Euphorbia echinus Hook, Euphorbia hernandez-pachecoi Cab., Withania frutescens Pauq., Isoplexis sceptrum (L.) Steud., and Senecio antieuphorbium (L.) Sch. Bip.), although they are not found in the archipelago, have been included because they may be of interest in chemotaxonomy due to their relation with endemisms of the Canary Isles. The order and circumscription of the families is that of Melchior in A. Engler's Syllabus der Pflanzenfamilien, ed. 12 (1964).
