متن کاملFive new iridoids from roots of Salvia digitaloides.
Five new iridoids, salvialosides A-E (compounds 1-5), together with fifty known compounds were isolated from the roots of Salvia digitaloides. The structures of the new compounds were completely elucidated using a combination of 2D NMR techniques (COSY, NOESY, HMQC and HMBC) and HR-ESI-MS analyses. The known compounds were identified by comparison of their spectroscopic and physical data with t...
