| Description | Isorhoifolin and vicenin II are main compounds of ethyl acetate fraction (EAcF) obtained from Erythrina velutina leaves, EAcF increases the cardiac contractile force by increasing the l-type calcium current and activating the adrenergic receptor pathway. |
| In vitro | From the crude ethanolic extract of the aerial parts of this plant, 23 compounds (phenylpropanoids, coumarins, flavonoids, and triterpenes) were isolated. Among these, eight compounds (salvianolic acid B, caftaric acid, cichoric acid, umbelliferone, aesculetin, apigenin-7-O-β-D-glucuronopyranoside, Isorhoifolin, and luteolin-4'-O-β-D-glucopyranoside) were detected for the first time in the genus Dracocephalum. Their structures were elucidated based on chemical and spectral data. The levels of most of the compounds detected in the cultivated sample were close to that of the wild sample, indicating the reproducibility of the biologically active compounds of D. palmatum through cultivation[1] |
