From the rhizoma of Peltoboykinia tellimoides (MAXIM.) HARA, two triterpene acids were isolated. One of them, a new triterpene, named β-peltoboykinolic acid (I), mp 220-222°(decomp.), [α]^<24>_D+114°, has been established to be olean-12-ene-3β-ol-27-oic acid and another, named α-peltoboykinolic acid (II), mp 234-236°, [α]^<17>_D+121°, to be urs-12-ene-3β-ol-27-oic acid, which is identical with a compound derived from quinovic acid by L. Ruzicka, et al. in 1946. These are the first examples of naturally occurring triterpene acids with the only carboxyl group at C-27 of ursane and oleanane types.
