OBJECTIVE
To investigate antioxidant activities and life span prolonging effects of the extracts from the roots of Incarvillea younghusbandii Sprague, and to study the correlations between these activities and the polar intensity of the extracts.
METHODS
Five extracts (IYS1, IYS2, IYS3, IYS4 and
For the purpose of preventative treatment for oxidative stress-mediated diseases and anti-aging, a high-antioxidant compound was isolated from the roots of Incarvillea younghusbandii Sprague for the first time through silica gel column chromatography, reverse-phase C18 column chromatography and
Incarvillea compacta Maxim is a traditional Tibetan plant widely used to treat rheumatic pain and bruises. We conducted qualitative analyses by liquid chromatography-mass spectrometry and quantitative analyses of the total phenols, flavonoids, and alkaloids content of different extracts of
Using a bioassay-guided fractionation technique, two compounds were isolated from the roots of Incarvillea younghusbandii Sprague through silica gel, reverse-phase C18 column chromatography and reverse-phase HPLC. Their structures were identified as acteoside (1) and isoacteoside (2) by ESI-MS,
A comparative study was performed on various parts (shoots, roots and flowers) of Incarvillea emodi. The alcoholic extracts of different parts were fractionated with solvents of different polarity and studied for the determination of total polyphenol content and total antioxidant potential.
(E)-2-(1-hydroxyl-4-oxocyclohexyl) ethyl caffeine (HOEC), a naturally caffeic ester isolated from Incarvillea mairei, has been reported to possess anti-inflammatory activity by targeting 5-lipoxygenase. However, its other potential activities have yet to be explored. In this study, we measured
