Abstract:Medicinal plants play an important role in human health.Through field research and literature review, 725 species belonging to 152 families and 506 genera of medicinal plants were recorded in Macao, accounting for 40.08% of the total vascular plant species in Macao. Among them, the number of species in Asteraceae, Euphorbiaceae, and Papilionaceae ranked the top three, and the number of species of trees, shrubs, herbs and vines accounted for 25%, 18%, 47% and 10%, respectively. In addition, whole grasses or whole plants, roots and leaves were the main medicinal parts. Some suggestions on the main problems of the medicinal plant application in Macao are put forward: strengthening the basic research of native medicinal plants resources, giving full play to their health and medicinal effects,and enriching their species and quantities in public green spaces.
