Iridoid-specific glucosyltransferase from Gardenia jasminoides.
Iridoids are one of the most widely distributed secondary metabolites in higher plants. They are pharmacologically active principles in various medicinal plants and key intermediates in the biosynthesis of monoterpenoid indole alkaloids as well as quinoline alkaloids. Although most iridoids are present as 1-O-glucosides, the glucosylation step in the biosynthetic pathway has remained obscure. W...
متن کاملIridoids from Gardenia jasminoides Ellis
Three new iridoids, Gardenal-I (1), Gardenal-II (2) and Gardenal-III (3), together with nine known iridoid glycosides; geniposide (4), 6-β-hydroxy geniposide (5), 6-α-hydroxy geniposide (6), 6-α-methoxy geniposide (7), feretoside (8), genipin-1-β-gentiobioside (9), shanzhiside (10), lamalbidic acid (11) and picrocrocinic acid (12) were isolated from EtOH extract of G. gasminoides. The structure...
متن کاملIridoid 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...
متن کاملIridoid 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.
متن کاملSelective Extraction of Gardenia Yellow and Geniposide from Gardenia jasminoides by Mechanochemistry.
A novel method for the selective extraction of gardenia yellow and geniposide from Gardenia Jasminoides, based on a mechanochemical method is described. Without the need of complex separation techniques, gardenia yellow compliant with the national standard could be extracted in a simple fashion. The optimal ball-milling conditions determined were as follows: 30% g/g. active carbon milling at 20...
