J Asian Nat Prod Res. 2012;14(7):618-25. | New terpenes from Salvia palaestina Benth. and Salvia syriaca L. growing wild in Jordan.[Pubmed: 22574636] | METHODS AND RESULTS:
The novel seco-ursane-type triterpenoid 3β,11α-dihydroxy-17,22-seco-17(28), 12-ursadien-22-oic acid (1) was isolated for the first time from a natural source from two Salvia species growing wild in Jordan, Salvia palaestina Benth. and Salvia syrica L. In addition to compound 1, S. syriaca afforded a new sesquiterpene named syriacine (2). S. palaestina also afforded 15 other known compounds, 6 of which are isolated for the first time from the plant, and these include velutin, Hyptadienic acid, cirsilineol, 2α,3β-dihydroxyurs-12-en-28-oic acid, 2α,3α-dihydroxy-24-nor-4(23),12-oleanan-28-oic acid, and 2α,3β,24-trihydroxyurs-12-en-28-oic acid. S. syriaca also afforded 16 other known compounds, 7 of which are isolated for the first time from the plant.
CONCLUSIONS:
These are 1α,3α-dihydroxyolean-9(11),12-diene, maslinic acid, 2α,3β,24-trihydroxyolean-12-en-28-oic acid, 11-oxo-oleanolic acid, 11-oxo-ursolic acid, poriferast-5-en-3,7-diol, and pectolinangenin. |
