ABSTRACT A triterpenetricarboxylic acid with a novel 2,3-secolanostane-type framework named lanopropic acid ( 1) was isolated from the aerial parts of Schisandra propinqua var. propinqua. The structure of 1 was elucidated as 2,3-secolanost-9(11),24( Z)-diene-2,3,26-trioic acid on the basis of spectroscopic techniques and X-ray diffraction studies. This is the first report of natural occurrence of 2,3-secolanostane type triterpenoid.

    ABSTRACT: Over the past 30 years, the family Schisandraceae has received considerable attention in chemical and biological studies. In particular, the discovery of a series of highly oxygenated triterpenoids with different skeletons has further increased the interest in this family. This review covers the structures, proposed biosynthetic pathways, total synthesis and biological activities of these and other triterpenoids from the plants of the family Schisandraceae. There are 100 references.
