Iridoid glycosides from Scrophularia ningpoensis

Three new minor iridoids were isolated from the roots of Scrophularia ningpoensis. They were elucidated as 8-Oferuloylharpagide, 8-O-(2-hydroxy-cinnamoyl)harpagide and 6-O-a-D-galactopyranosylharpagoside. # 1998 Published by Elsevier Science Ltd. All rights reserved.

Drought stress increases iridoid glycosides biosynthesis in the roots of Scrophularia ningpoensis seedlings

In China, Scrophularia ningpoensis Hemsl (Scrophulariaceae) has been cultivated for many years; however, the effects of drought on the content of secondary metabolites in Radix Scrophulariaceae are still unknown. The study investigated the medicinal components of S. ningpoensis including harpagoside, aucubin, catalpol, harpagide, and cinnamic acid in relation to drought stress. Three ecotypes o...

Scropolioside-D2 and harpagoside-B: two new iridoid glycosides from Scrophularia deserti and their antidiabetic and antiinflammatory activity.

Five iridoid glycosides, including the two new compounds scropolioside-D(2) (1) and harpagoside-B (2), were isolated from the aerial parts of Scrophularia deserti DEL (Scrophulariaceae). Their structures were elucidated on the basis of spectral data to be 6-O-[2",4"-di-O-acetyl-3"-O-trans-cinnamoyl)-alpha-L-rhamnopyranosyl]-8 alpha-hydroxymethyl-1 alpha,5 beta,6 alpha,7 alpha,9 beta-pentahydro-...

Iridoid glycosides from Globularia davisiana.

From the ethanolic extract of the aerial parts of Globularia davisiana, a new iridoid glycoside, davisioside (1), was isolated. Davisioside (1) comprises a rare iridoid aglycone structure with a saturated double bond between C-3 and C-4. Nine known iridoid glycosides, asperuloside (2), alpinoside (3), geniposide (4), globularin (5), globularicisin (6), 10-O-benzoylcatalpol (7), lytanthosalin (8...
