Anthraquinones from natural and transformed roots of Plocama pendula.

Five new and 15 known anthraquinones have been isolated from Plocama pendula root cultures transformed by Agrobacterium rhizogenes. The new anthraquinones were named balonone, balonone methyl ether, and plocamanones A, B, and C. Moreover, lucidin dimethyl ether was obtained for the first time as a natural compound.

Triterpenes from natural and transformed roots of Plocama pendula.

Plocama pendula root cultures transformed by Agrobacterium rhizogenes were established. From these cultures two new pentacyclic triterpenes, 3-epi-pomolic acid 3alpha-acetate (3alpha-acetoxy-19alpha-hydroxyursa-12-en-28-oic acid) (1) and baloic acid (3alpha-acetoxy-19alpha-hydroxyursa-12,20(30)-dien-28-oic acid) (9), were isolated. The former was also obtained from P.
