Sugar esters from Globularia orientalis.
From the methanolic extract of the underground parts of Globularia orientalis, a new antioxidant sugar ester was isolated. The structure of the new compound, globularitol (1), was identified as 6-O-feruloyl-beta-D-glucopyranosyl-(1-->6)-glucitol by spectroscopic methods (1D and 2D NMR, ESI- and FAB-MS) and confirmed by chemical means.
متن کاملIridoids from Globularia dumulosa.
Two new iridoids, 10-O-benzoylglobularigenin (1) and dumuloside (2) were isolated from the aerial parts of Globularia dumulosa together with seven known iridoid glucosides, davisioside (3), aucubin (4), melampyroside (5), catalpol (6), 10-O-benzoylcatalpol (7), alpinoside (8) and deacetylalpinoside (9). Three phenylethanoid glycosides, verbascoside, decaffeoyl-verbascoside, leucosceptoside A an...
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 کاملFerulone A and ferulone B: two new coumarin esters from Ferula orientalis L. roots.
Ferula orientalis (Apiaceae) is a well-known perennial herb growing wild in Iran used in traditional medicine. To perform phytochemical studies, dried ground roots of F. orientalis were sequentially Soxhlet-extracted using n-hexane, dichloromethane and methanol. A combination of vacuum liquid chromatography and preparative thin-layer chromatographic analyses were performed to isolate coumarin e...
متن کاملEnzymatic Production of Sugar Fatty Acid Esters
Sugar fatty acid esters (SFAE) are well known as bio-surfactants. Their excellent biodegradability as well as the fact that they are tasteless, odorless, nontoxic, non-irritant and non-ionic explains their increasing importance in numerous areas. On the other hand, for a long time, large scale production of SFAE remained mainly in the realms of organic chemistry and chemical processing. Chemica...
