Pressurized liquid extraction of medicinal plants - ScienceDirect
The suitability of pressurized liquid extraction (PLE) in medicinal plant analysis was investigated. PLE extracts from a selection of representative herbs were compared with extracts obtained according to Pharmacopoeia monographs with respect to yield of relevant plant constituents extraction time and solvent consumption.

Rapid green synthesis of silver and gold nanoparticles using ...
Dendropanax morbifera Léveille is an oriental medicinal plant that is traditionally used in folk medicine and grows in a specific region of South Korea. We aimed to enhance the utilization of D. morbifera medicinal plants for synthesis of silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs). D. morbifera leaf extract acted as both a reducing and a stabilizing agent that rapidly synthesized Dendropanax AgNPs (D-AgNPs) and Dendropanax AuNPs (D-AuNPs).
A Review on the Extraction Methods Use in Medicinal Plants ...
Medicinal plants are gaining much interest recently because their use in ethno medicine treating common disease such as cold fever and other medicinal claims are now supported with sound scientific evidences. The study on medicinal plants started with extraction procedures that play a critical role to the extraction outcomes (e.g. yield and phytochemicals content) and also to the consequent ...
Anticancer antimicrobial antioxidant and catalytic ...
In the present study noble metal nanoparticles such as silver and gold were prepared using an aqueous leaf extract of a medicinal plant Bauhinia purpurea. The leaf extract performed as both reducing and stabilizing agents for the development of nanoparticles. The formations of silver and gold nanoparticles were confirmed by observing the surface plasmon resonance peaks at 430 nm and 560 nm respectively in UV-Vis absorption spectrum.
