CHEMICAL CONSTITUENTS OF Flcus linearifolia AND Ficus triangularis

摘要

Ficus linearifolia Elmer is an endemic Philippine fig tree distributed in the forests of Luzon, Negros, and Leyte at altitudes up to 900 m above sea level [1]. It was earlier considered as a mere variety of Ficus botryocarpa Miq. [2]. This fig tree was first described in 1907 as an erect tree that reaches a height of 20 m and bears linear lanceolate leaves that are more or less scattered but usually confined towards ends of the branchlets. It grows in low damp wooded ground or along streams in deep ravines at the base of Mt. Banahao (Lucban, Luzon Island) at 750 m above sea level [3]. This fig tree is locally known in the Philippines as daing-daing [4]. Ficus triangularis, commonly known as triangular fig and sweetheart tree, is a native to tropical Africa. It was recently introduced in the Philippines as an ornamental tree [5].
