There are about 90 species of Elaeagnus around the world. The majority are native to the temperate and subtropical regions in Asia, of which nine species can be found in Taiwan . Many species of Elaeagnus are considered as folk medicinal plants, e.g., E. umbellata , E. pungens , E. angustifolia , and E. multiflora . Triterpenoids, steroids, and flavonoids have been isolated from several species of Elaeagnus, e.g., E. umbellata , E. bockii , E. orientalis , and E. pungens [9, 10]. In the course of screening for biologically and chemically novel agents from Formosan elaeagnaceous plants, E. glabra Thunb. was chosen for further phytochemical investigation. This is also being studied and published for the first time.
E. glabra Thunb. is an evergreen shrub or small tree with alternate leaves; it inhabits East Asia and is reported to have anticancer, antibacterial, procoagulant, anti-asthmatic, and antidiarrheal effects . These observations provide useful...
