The genus Hemandia L. of the family Hemandiaceae is represented by evergreen trees and shrubs [1]. Hemandia consists of approximately 24 species and is widely distributed in pantropical regions [2]. In terms of their economic applications, timbers of some species of Hemandia are used locally for crates, boxes, and cheap plywood [3]. Thus far, six species and one variety have been investigated for their secondary... 

The taxonomic characterization of Hemandia was described by Verdcourt [1] as follows ... 

Three Hemandia species, namely, H. moerenhoutiana, H. nymphaeifolia (a synonym of H. peltata according to Kubitzki [2]), and H. voyronii, have been used ethnobotanically by inhabitants of Tonga and Madagascar to treat malaria [11,12], postpartum hemorrhage [13], retained placenta [13], and morning sickness [14],...

Biological evaluations of isolates from Hemandia species published to date have focused mainly on their cytotoxic, potential cancer chemopreventive, antiplatelet aggregation, and antimalarial activities. Bioactive compounds from the genus Hemandia with their individual activities of these types will be summarized specifically in the following paragraphs. 

Corydine (25i) was isolated from Thalictrum dioicum (424) and from the bark of Cinnamomum (425), hernangerine (25c) from Hemandia papuana (426), and boldine (24e) and laurolitsine (24b) from Litsea turfosa...
