Sesquiterpenes from Blumea balsamifera.
Five new guaiane sesquiterpenes, blumeaenes E1 (1), E2 (2), K (3), L (4), and M (5), and one new eudesmane sesquiterpene, samboginone (6), along with three known compounds, cryptomeridiol, 3,3',5,7-tetrahydroxy-4'-methoxyflavanone, and austroinulin, were isolated from the leaves of the Philippine medicinal herb sambong, Blumea balsamifera. The absolute configuration of the new guaiane core was det…

New sesquiterpeniod esters form Blumea balsamifera (L.) DC. and their anti-influenza virus activity.
Phytochemical studies led to the isolation of five new sesquiterpeniod esters, named balsamiferine N-R, along with ten known compounds (6-15) from the leaves of Blumea balsamifera (L.) DC. The skeletons of nine known sesquiterpeniods belong to guaiane and eudesmane. The structures of the new compounds including their absolute configurations were elucidated by comprehensive spectroscopic analysis, …

New α-pyrones from an endophytic fungus, Hypoxylon investiens J2.
Four new α-pyrones, hypotiens A-D (1-4), were isolated from a fungal endophyte, Hypoxylon investiens J2, harbored in the medicinal plant Blumea balsamifera. Their structures were determined through detailed HRMS and NMR spectroscopic data. Compounds 1-4 are new α-pyrone derivatives containing an unusual dimethyl substitution in the highly unsaturated side chain. Their plausible biosynthetic pathwa…

Antifungal metabolites from Blumea balsamifera.
The leaves of Blumea balsamifera afforded icthyothereol acetate, cryptomeridiol, lutein, and beta-carotene. The structures of icthyothereol acetate (1) and cryptomeridiol (2) were elucidated by extensive 1D and 2D NMR spectroscopy, while those of lutein and beta-carotene were identified by comparison with literature data. Antimicrobial tests indicated that 1 has moderate activity against the fungi…

Ethnomedicinal plant diversity in Thailand.
Plants have provided medicine to humans for thousands of years, and in most parts of the world people still use traditional plant-derived medicine. Knowledge related to traditional use provides an important alternative to unavailable or expensive western medicine in many rural communities. At the same time, ethnomedicinal discoveries are valuable for the development of modern medicine. Unfortunate…

Green Preparation and Antibacterial Activity Evaluation of AgNPs-Blumea balsamifera Oil Nanoemulsion.
Bacterial infection is a thorny problem, and it is of great significance to developing green and efficient biological antibacterial agents that can replace antibiotics. This study aimed to rapidly prepare a new type of green antibacterial nanoemulsion containing silver nanoparticles in one step by using Blumea balsamifera oil (BBO) as an oil phase and tea saponin (TS) as a natural emulsifier and r…

Blumeaxanthene II, a novel xanthene from Blumea riparia DC.
A novel xanthene (1), blumeaxanthene II, was isolated from the aerial parts of Blumea riparia (Bl.) DC., a Chinese medicinal plant with hemostatic properties, and its structure was determined by extensive spectroscopic analyses. This compound is the first example of a halogenated xanthene from a natural plant, and a biosynthetic pathway was proposed. Blumeaxanthene II was also tested against Bel-7…

Isolation of Various Flavonoids with TRAIL Resistance-Overcoming Activity from Blumea lacera.
Eighteen compounds, including fourteen flavonoids (1-14), one steroid (15), two fatty acids (16,17), and one nitrogen-containing compound (18), were isolated from the methanol extract of the whole Blumea lacera plant collected in Thailand. Compounds 1-11 and 15-17 exhibited tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) resistance-overcoming activity. Among them, bonanzin (2) and …
