“…C. sinensis leaves have a significant amount of flavandiols, alkaloids, flavanols, and phenolic acids including catechin compounds. In a study conducted by Joo et al (), the HPE technique was more efficient as compared to other techniques as extracts from this method showed enhanced antioxidant effects, a higher content of phenols, and amino acids compared to those of the ultrasonicated and leached extracts. The enhanced effects were highest at 100 MPa and hence the effects are pressure‐dependent (Komes, Horžić, Belščak, Ganić, & Vulić, ).…”

“…(Chen, Meng, Zhang, & Liu, ). High pressure extraction (HPE) has been recently applied to extract various compounds, such as polysaccharides from the Ligusticum rhizome (Liu et al, ), anthocyanins from black chokeberry (Grunovaitė, Pukalskienė, Pukalskas, & Venskutonis, ), ginsenosides from ginseng powder (Shin et al, ), rutin from Amaranthus leaves (Kraujalis, Venskutonis, Ibanez, & Herrero, ), flavonoids and phenolic compounds from Camellia leaf extracts (Joo et al, ) corilagin from the pericarp of longan fruit (Prasad, Yang, Zhao, Ruenroengklin et al, ), and various other bioactive materials from different plant parts, such as the extraction of green tea phenolic compounds and caffeine (Jun, ; Xi et al, ; Xi, Shen, Li, & Zhang, ), flavonoids from propolis (Shouqin, Jun, & Changzheng, ) and xanthohumol from hop (Santos et al, ). Studies have shown a number of advantages of HPE technique, such as shortened processing time, lower power consumption (Corrales et al, ; Jun, ; Liao, Liu, He, Chen, & Zhang, ), higher extraction yields, and fewer impurities in the extraction liquid over the other extraction methods.…”

Extraction of bio‐active compounds has become very important as these compounds show various characteristics which are beneficial to health, such as antioxidant, anti‐carcinogenic and antimicrobial properties. High pressure extraction (HPE) can be included among the recent and novel methods for extracting bioactive compounds from natural materials. The high pressure is applied to stimulate various phenomena (such as transition of phase from one form to another, change in reaction dynamics, change in molecular structure, etc.) which induces a reaction in a direction promoting a decrease in volume hence resulting in the enhancement of extraction efficiency. This article presents a comprehensive review of HPE and its applications in various food products and wastes. The review highlights that HPE is potential option for conventional extraction methods to meet the industrial demand. As most of the research has been conducted at laboratory scale level therefore recommendations for scaling up of the HPE process are made to evaluate the performance at commercial levels. Practical applications Extraction is considered to be a vital unit operation in downstream processes. However the conventional methods of extraction have various disadvantages viz. time and solvent consuming, energy deficient, poor extraction, risky to environment. High pressure extraction has a huge potential to partially or fully overcome these disadvantages. This review article presents the working mechanism and principle of HPE, and recent research conducted to evaluate the HPE process of potential bio‐active compounds from various plant and animal sources. HPE has been found to facilitate the recovery of these potential bio‐active compounds in their best natural form. Also it is recommended that HPE could be scaled up to make the extraction process relatively easy and efficient at commercial level.

“…During the treatment of DHPM, the pressure difference between the inside and outside of the cell will be increased. In response to the increased pressure, the solvent flux will be increased, allowing the solvents permeating into the cell and accelerating the extraction efficiency [28]. In addition, cell disintegration due to cavitation may be another main reason for an increased extraction yield [29].…”

“…However, the main drawback of these methods are the loss of phenolic compounds and their bioactivities due to oxidation, ionization and hydrolysis caused by long extraction time and high extraction temperature during extraction process [ 11 , 12 ]. In this context, other innovative extraction techniques, including ultrasonic assisted extraction (UAE), microwave assisted extraction (MAE), enzymatic assisted extraction (EAE) and pressurized assisted extraction (PAE), have been developed [ 13 , 14 , 15 , 16 ]. Among them, EAE is considered as a moderate, efficient, and environment-friendly extraction method, and has been proven to be effective in improving the yield of target compounds [ 15 ].…”

Stems are the important residues of Trapa quadrispinosa Roxb., which are abundant in phenolic compounds. Ultrasonic-assisted enzymatic extraction (UAEE) is confirmed as a novel extraction technology with main advantages of enhancing extraction yield and physiological activities of the extracts from various plants. In this study, UAEE was applied to obtain the highest yield of phenolic content, strongest antioxidant, and antitumor activities and to optimize the extraction conditions using response surface methodology (RSM). The extracts from the stems of T. quadrispinosa were characterized by determination of their antioxidant activities through 2,2-azinobis(3-ethylbenzthiazoline)-6-sulfonic acid (ABTS), 1,1-Diphenyl-2-picrylhydrazxyl (DPPH) radical scavenging, total antioxidant capacity (TAC), ferric reducing antioxidant capacity (FRAC) methods and of their antitumor activity by MTT method. The selected key independent variables were cellulase concentration (X1: 1.5%–2.5%), extraction time (X2: 20–30 min) and extraction temperature (X3: 40–60 °C). The optimal extraction conditions for total phenolic content (TPC) value of the extracts were determined as 1.74% cellulase concentration, 25.5 min ultrasonic extraction time and 49.0 °C ultrasonic temperature. Under these conditions, the highest TPC value of 53.6 ± 2.2 mg Gallic acid equivalent (GAE)/g dry weight (DW) was obtained, which agreed well with the predicted value (52.596 mg GAE/g·DW. Furthermore, the extracts obtained from UAEE presented highest antioxidant activities through ABTS, DPPH, TAC and FRAC methods were of 1.54 ± 0.09 mmol Trolox equivalent (TE)/g·DW; 1.45 ± 0.07 mmol·TE/g·DW; 45.2 ± 2.2 mg·GAE/g·DW; 50.4 ± 2.6 μmol FeSO4 equivalent/g·DW and lowest IC50 values of 160.4 ± 11.6 μg/mL, 126.1 ± 10.8 μg/mL, and 178.3 ± 13.1 μg/mL against Hela, HepG-2 and U251 tumor cells, respectively. The results indicated that the UAEE was an efficient alternative to improve extraction yield and enhance the antioxidant and antitumor activities of the extracts. The phenolic extracts from the stems of T. quadrispinosa had significant antioxidant and antitumor activities, which could be used as a source of potential antioxidant and antitumor agents.
