Triterpenoids from Salvia argentea var. aurasiaca (Pomel) Batt. & Trab. and their chemotaxonomic significance.
Ten triterpenoids were isolated from the exudate of Salvia argentea L. var. aurasiaca (Pomel) Batt. & Trab. Their structures were elucidated by 1D and 2D NMR and HRESIMS analyses as 11α-methoxyurs-12-ene-1β,3β,15α-triol (1), urs-12-ene-1β,3β,11α,15α-tetraol (2), 11α-methoxyurs-12-ene-1β,3β-diol (3), 1β,3β,15α-trihydroxy-11α-methoxyurs-12-en-28-al (4), 1β,3β,15α-trihydroxyurs-12-en-28-al (5), urs-12-ene-1β,3β,15α,28-tetraol (6), 11α-methoxyurs-12-ene-1β,3β,28-triol (7), 13β,28-epoxyurs-12-ene-1β,3β-diol (8), urs-12-ene-3β,7β,15α,28-tetraol (9) and olean-12-ene-3β,7β,15α,28-tetraol (10). A chemotaxonomic survey of the triterpenoids of Salvia species show that triterpenoids from the exudate of S. argentea var. aurasiaca (Pomel) Batt. & Trab., provide some features, such as hydroxylation at C-15, and hydroxylation at C-7. On this basis, S. argentea L. var. aurasiaca (Pomel) Batt. & Trab., is quite different from S. argentea L.
