Ursane- and oleanane-type triterpenes from Ternstroemia gymnanthera callus tissues.
    Journal of natural products, 2003, Volume: 66, Issue:8

    An investigation on the constituents of the callus tissues of Ternstroemia gymnanthera has led to the isolation of five phytosterols, 15 known triterpenoids, and four new triterpenoids (1-4). The new compounds were characterized by spectroscopic study as 3-epi-corosolic acid lactone (2 alpha,3 alpha-dihydroxyurs-11-en-13 beta,28-olide) (1), 3-epi-ternstroemic acid (2 alpha,3 alpha-dihydroxyurs-12-en-11-on-28-oic acid) (2), ternstroemic acid (2 alpha,3 beta-dihydroxyurs-12-en-11-on-28-oic acid) (3), and gymnantheraic acid (2 alpha,3 alpha-dihydroxy-11 alpha-methoxyurs-12-en-28-oic acid) (4). The isolated triterpenes were compared with those from actinidiaceous plant callus tissues from a chemotaxonomic point of view.
