Dataset on the compounds from the leaves of Vietnamese and their anti-inflammatory activity.

has a history of traditional applications including treating dyspepsia, apoplexy, headaches, abdominal pain, abdominal distension, and leg edema [1]. It is also employed for alleviating allergies, inflammation, pain relief, promoting blood circulation, addressing costal chondritis, and sinusitis [2]. Research into the chemical composition of has revealed the presence of lignans, flavonoids, lactones, and essential oils [1,[3], [4], [5]. While some investigations have explored the inhibitory effects of extracts and lignan compounds from this species on NO production [6], [7], [8], there has been no research into the flavonoids isolated from this plant and their potential for inhibiting NO production, given our reachable referencing. The ethyl acetate (EtOAc) soluble fraction of leaves was subjected to column chromatography (CC) using silica gel and Sephadex LH-20 for compound isolation. Nuclear magnetic resonance (NMR) data primarily facilitated the determination of isolated compound structures. Anti-inflammatory activity was evaluated against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in macrophage RAW264.7 cells. Anti-inflammatory activity-guided fractionation led to the isolation of twelve secondary metabolites (-). The compounds were identified as quercetin (), kaempferol (), rhamnetin (), quercitrin (), hyperoside (), reynoutrin (), guaijaverin (), afzelin (), astragalin (), rutin (), kaempferol-3-O-rutinoside (), and rhamnetin-3-O-rutinoside (. Compounds , and were isolated from for the first time. Evaluation against LPS-induced NO production in macrophage RAW264.7 cells showed that exhibited potent inhibitory activity with IC values of 15.45, 25.44, and 19.82 µM, respectively. Compounds demonstrated IC values ranging from 42.15 to 67.42 µM, while exhibited inactivity (IC > 100 µM).
