Phenolic compounds and flavonoids as plant growth regulators from fruit and leaf of Vitex rotundifolia.
Five phenolic compounds, 4-hydroxybenzoic acid methyl ester (1), vanillic acid methyl ester (2), 4-hydroxy benzaldehyde (3), 4-hydroxybenzoic acid (4) and ferulic acid (5), and four flavonoids, 5,5'-dihydroxy-4',6,7-trimethoxyflavanone (6), luteolin (7), vitexicarpin (8) and artemetin (9), were isolated from fruits and leaves of Vitex rotundifolia L. The biological activities of these nine comp...
متن کاملAnti-inflammatory constituents from the fruits of Vitex rotundifolia.
Three new diterpenes (7, 15 and 17) and two new neolignans (19 and 20) along with nineteen known compounds have been isolated from the fruits of Vitex rotundifolia. Their structures were elucidated by a combination of 1D and 2D NMR, HRESI-MS, and CD data. All isolates were tested for their inhibitory activities on LPS-induced nitric oxide production in RAW264.7 cells. Of these, compounds 3, 4, ...
متن کاملAntioxidative Constituents from the Twigs of Vitex rotundifolia
In the course of screening for antioxidant compounds by measuring the radical scavenging effect on DPPH (1,1-diphenyl2-picrylhydrazyl), a total extract of the twigs of Vitex rotundifolia (Verbenaceae) was found to show potent antioxidant activity. Subsequent activity-guided fractionation of the methanolic extract led to the isolation of three iridoid compounds, 10-O-vanilloylaucubin (1), 10-O-p...
