Pressurized hot water extraction (PHWE).

Evaluation of pressurized liquid extraction and pressurized hot water extraction for tanshinone I and IIA in Salvia miltiorrhiza using LC and LC-ESI-MS.

Pressurized liquid extraction (PLE) and pressurized hot water extraction (PHWE) using a laboratory-made system are applied for the extraction of thermally labile components such as tanshinone I and IIA in Salvia miltiorrhiza. PLE and PHWE are carried out dynamically at a flow of 1 mL/min, temperature between 95-140 degrees C, applied pressure of 10-20 bars, and extraction times of 20 and 40 min...

Optimization of pressurized hot water extraction of Lavandin essential oils via central composite design

Pressurized hot water extraction (PHWE) and hydrodistillation were compared for the extraction of essential oil from Lavandin. Using GC-FID analysis in conjunction with central composite design, the maximum extraction yield was obtained for temperature of 148 o C, pressure of 33.7 (bar), static time of 10.7 (min), dynamic time of 17.6 (min), and flow rate of 0.69 (mL/min). The PHWE is a practic...

Highly Isoxanthohumol Enriched Hop Extract Obtained by Pressurized Hot Water Extraction (phwe). Chemical and Functional Characterization

Evaluation of the extraction efficiency of thermally labile bioactive compounds in Gastrodia elata Blume by pressurized hot water extraction and microwave-assisted extraction.

Our earlier work showed that the stability of the bioactive compounds gastrodin (GA) and vanillyl alcohol (VA) in Gastrodia elata Blume behaved differently with varying compositions of water-ethanol using pressurized liquid extraction (PLE) at room temperature. To have a better understanding of the extraction process of these thermally labile compounds under elevated temperature conditions, pre...

novel process for extraction of natural sweetener from licorice Glycyrrhiza glabra) roots

Pressurized hot water extraction (PHWE) is a very useful technique for recovering bioactive molecules from natural materials using subcritical compressed liquid water in the temperature range of 50–150 ◦C. A novel process has been developed for making a natural sweetener from licorice (Glycyrrhiza glabra) roots involving selective chemical reaction and easy separation, for recovering mono-ammon...
