Seven known compounds, including two neolignans, four lignans, and one flavane were isolated from the methanol extract of Pandanus tonkinenis fruits. Their structures were determined to be ficusal, vladinol F, medioresinol, syringaresinol, lariciresinol, secoisolariciresinol, and luteoliflavan by analysis of MS and NMR data as well as by comparison of their spectral data with those reported in the literature.

The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

Belamcanda chinensis (L.) DC is a popular ornamental and medicinal plant belonging to the Iridaceae family. Its rhizomes are used in Vietnamese traditional medicine for the treatment of inflammation and respiratory disorders, such as asthma, tonsillitis, coughing, and pharyngitis. In this study, four iridal-type triterpenoid derivatives (1–4) and four isoflavonoids (5–8) have been isolated from the methanol extract of Belamcanda chinensis roots.

This study examined the phytochemical composition and algicidal effectiveness of Ludwigia octovalvis. The powder samples were extracted by ultrasound-assisted extraction with polar solvents (water-diluted ethanol, acetone, methanol, and water). The preliminary phytochemical analyses used standard procedures following Sofowora and Harborne.

Phytochemical studies on the methanolic extract of Barleria prionitis Linn. collected in Luang Namtha province, Laos have led to the isolation and structural elucidation of four secondary metabolites, including two iridoid glycosides: shanzhiside methyl ester (1), barlerin (2); one sterol: stigmasterol (3); and a sterol glycoside: β-sitosterol glycoside (4). Their structures were identified by spectroscopic analyses such as 1D and 2D NMR spectra.
