OBJECTIVE
To investigate chemical constituents from acetyl acetate extract fraction of Incarvillea delavayi.
METHODS
The chemical constituents were isolated by chromatographic techniques with silica gel, Sephadex LH-20 and semipreparative HPLC. The structures of those compounds were identified by
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
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,
OBJECTIVE
To study chemical constituents of Incarvillea arguta and their accelerating PC-12 cell differentiation.
METHODS
The constituents were isolated and repeatedly purified on silica gel column chromatography, and were identified on the basis of physicochemical and spectroscopic analysis. The
OBJECTIVE
To study the chemical constituents of the roots of Incarvillea mairei.
METHODS
The chemical constituents were isolated and purified by chromatographic techniques with silica gel, Sephadex LH-20 column, and preparative TLC. Structures of the compounds were identified by spectroscopic
