The antioxidant, radical-scavenging, anti-inflammatory, cytotoxic and antibacterial activities of methanolic extracts of seven Hedyotisspecies were investigated. The antioxidant activity was evaluated by the ferric thiocyanate (FTC) and thiobarbituric acid (TBA) methods while the radical scavenging
BACKGROUND
Hedyotis pilulifera (Pit.) T.N. Ninh (Rubiaceae) has been used in Vietnamese ethnomedicine; the methanol extract exhibited antibacterial activity in our preliminary screening.
OBJECTIVE
In this study, compounds from H. pilulifera were isolated and their antibacterial activity in vitro was
A new iridoid, 10-acetylborreriagenin (1), and five known iridoid glycosides (2-6), were isolated from the aerial parts of Hedyotis pilulifera. Their structures were elucidated by spectral analyses, including 1D- and 2D-NMR, and HR-ESI-MS, and comparisons with the NMR data reported in the
