The essential oil were extracted from the leaf of Phoebe bournei (Hemsl.) Yang by a hydrothermal method and then analyzed by gas chromatography-mass spectrometry. The leaf oil mainly included α-copaene (5.44%), α-muurolene (7.32%), δ-cadinene (11.44%), 1s-calamenene (5.18%). Phoebe bournei (Hemsl.)
The essential oil from the leaves of Phoebe formosana from Taiwan was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Seventy-one compounds were identified, representing 100% of the oil. The main components identified were a-humulene (16.8%),
The oxoaporphine alkaloid lysicamine (1), and three proaporphine alkaloids, litsericinone (2), 8,9,11,12-tetrahydromecambrine (3) and hexahydromecambrine A (4) were isolated from the leaves of Phoebe grandis (Nees) Merr. (Lauraceae). Compounds 2 and 3 were first time isolated as new naturally
We synthesized silver nanoparticles using thirty Chinese plant extracts via a green synthetic strategy. UV-visible spectra showed that the silver nanoparticles have an absorbance at 450 nm. Among the thirty extracts, seven extracts (Cratoxylum formosum, Phoebe lanceolata, Scurrula parasitica,
