A new triterpenoid named uncargenin D with a structure of 3β, 19α-dihydroxy-urs-5, 12-di en-28-oic acid(Ⅸ), and four known compounds were isolated from the ethanolic extract of twig and leaf of Uncaria rhynchophylla Miq. Jacks. The four known compounds were:3β, 6β, 19α-trihydroxy-23-oxo-urs-12 en-oic acid (Ⅹ), 3β-hydroxy-urs-12 en-27, 28-dioic acid (Ⅺ), which were isolated for the first time from Un caria, β-sitosterol (Ⅻ)and scopoletin ().
