Homogenate-assisted high-pressure disruption extraction for determination of phenolic acids in Lonicerae Japonicae Flos.

An effective method based on the combined homogenate-assisted high-pressure disruption extraction (HHPDE) was applied to the extraction and determination of the main phenolic acid compounds from Lonicerae Japonicae Flos. The optimized HHPDE showed competitive advantage in yield (The extraction yields of NCA, CA, 3,5DCA and 4,5DCA in HHPDE were 1.21, 1.

Ganoderin A, a novel 9,11-secosterol from Ganoderma lucidum spores oil.

In this study, four sterols were isolated from the Ganoderma lucidum spores oil obtained via supercritical CO extraction. Four chemical constituents were ganoderin A (1), chaxine B (2), ergosterol, (3) and stellasterol (4). All the separated ingredients were characterized using spectral data interpretation and by comparing with reported data.
