However, these methods have limitations, including the use of organic solvents, long extraction times, and poor selectivity. In this study, hot compressed water extraction (HCWE) was evaluated as an alternative, and its performance was compared with conventional methods in terms of yield, physical characteristics, and concentration of key bioactive compounds. The HCWE was conducted at a constant pressure of 3.5 MPa and varying temperatures between 130°C and 200°C. The resulting extracts were analyzed using High-Performance Liquid Chromatography (HPLC) to quantify 6-gingerol, 6-shogaol, and 10-gingerol concentration. HCWE process at temperature of 140°C, pressure of 3.5 MPa and 30 minutes extraction time obtains higher extraction yield of 10.37 ± 0.33 % (g/g) in comparison with solvent extraction for 480 minutes at 7.57 ± 0.31 % (g/g). But it resulted in lower concentrations of 6-gingerol at 1957.22 ± 2.55 µg/g and undetectable levels of 6-shogaol. As temperature increased to 170°C, the concentration of 6-gingerol decrease to 851.95 ± 2.34 µg/g and 6-shogaol concentration increase to 1135.23 ± 1.18 µg/g demonstrating HCWE's temperature-driven selectivity. Above 170 °C, both compounds degraded significantly, and the extract quality declined. The HCWE extract resembled ginger oleoresin in texture and aroma, suggesting its suitability for similar applications. In contrast, solvent extraction produced a broader range of compounds but lacked selectivity. In conclusion, this study demonstrates that the HCWE process is a rapid, organic solvent-free extraction method which not only reduces processing time by more than 80 % compared with conventional solvent extraction, but also provides temperature-driven selectivity, underscoring its potential for greener, industrial-scale applications in functional food and phytochemical production. These findings highlight the promise of HCWE as a sustainable approach for phytochemical extraction and functional food development.</p>","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"75 3","pages":"347-356"},"PeriodicalIF":1.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147325978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among edible insects, Locusta migratoria (namely, migratory locust) (ML), which contains n-3 fatty acids capable of binding to multiple lipids, phytosterols, and dietary fiber chitin, are expected to be a therapeutic resource for ameliorating dyslipidemia as well as an alternative protein resource. We hypothesized that the ML supplementation represented the beneficial effect on lipid metabolism in the plasma and liver of male rats with dyslipidemia induced by an AIN-93G based diet containing a low level of orotic acid (OA) (0.6 % in diet) for two weeks. The 0.6 % OA treatment, which was determined in a preliminary study on loading dosage suitable for evaluating food ingredients, did not affect the growth and severe lipid accumulation, but induced liver hypertrophy with low-moderate hematological observations and hypertriglyceridemia. The ML supplementation led to a reduction in plasma triacylglycerol levels in OA-treated rats, particularly in the chylomicron, very-low-density lipoprotein, and low-density lipoprotein (LDL), particularly small-dense LDL, fractions. In the liver, the ML supplementation also significantly or slightly reduced mRNA expression related to lipogenesis and LDL uptake genes, including Srebf2, Ldlr, Psck9, Hmgcr, Acaca, and Scd1. Moreover, the ratios of n-3 fatty acids, such as α-linolenic and docosapentanoic acids, were increased in the liver and the indices representing fatty acid desaturation in the plasma were suppressed following the ML supplementation. These results have agreed with our hypothesis that the ML supplementation ameliorates lipid metabolism by modulating hepatic lipogenesis, fatty acid metabolism, and LDL receptor function in OA-treated rats.

A JIS standard liquid composition was proposed based on the AATCC liquid detergent composition (the 2003 AATCC standard reference liquid laundry detergent), and detergency evaluations were conducted using a Terg-O-Tometer using natural collar dirt-soiled cloth and various commercially available soiled cloths. As a result, in the cleaning experiment using collar dirt-soiled cloth, the new JIS liquid reference detergent showed the same detergency as the conventional JIS powder detergent and commercial liquid detergents. It also showed the same detergency as commercial liquid detergents for artificial sebum stains, indicating that it is suitable as an indicator detergent for commercial liquid detergents. However, it was confirmed that there are some points to note, such as the fact that liquid detergents have a weaker alkaline component and, therefore, have a lower detergency for artificial sebum stains than powder detergents and that the new JIS reference liquid detergent has a higher cleaning power for triacylglycerol stains than commercially available liquid and powder detergents due to their high surfactant concentration.</p>","PeriodicalId":16626,"journal":{"name":"Journal of oleo science","volume":"75 1","pages":"11-20"},"PeriodicalIF":1.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145900632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therapeutic drugs that can effectively improve the survival rate of DLBCL patients are lacking. Houttuynia cordata Thunb. is a well-known Asian medicinal and edible plant with anti-inflammatory and anti-tumor activities. This study investigated the potential therapeutic benefits of Houttuynia cordata Thunb. Essential Oil (HEO) on DLBCL. We found that HEO inhibited the proliferation of SUDHL-4 cells, induced apoptosis and cell cycle arrest at G0/G1 phase in a time and concentration-dependent manner. Moreover, intraperitoneal administration of HEO (70, 150, and 230 mg/kg) dose-dependently inhibited tumor growth of DLBCL in an athymic nude mouse xenograft model, while no significant changes in body weight were observed, indicating no obvious toxicity. Network pharmacology analysis indicated that HEO mainly regulated protein phosphorylation and PI3K/Akt signaling pathway. Phospho-specific protein microarray results also showed that HEO regulated the phosphorylation of PI3K/Akt signaling pathway. Further investigation confirmed that HEO significantly inhibited the protein expression of p-PI3K and p-Akt. In addition, HEO decreased the protein expression of B-cell lymphoma 2 (Bcl-2) and increased the protein expression of Bcl-2-associated X (Bax) and caspase-3. Compound-target docking results displayed that bornyl acetate (the main components of HEO), caryophyllene oxide and terpineol had strong binding interactions with the active sites of PI3K and Akt, indicating they contribute to the therapeutic effect.

This scoping review aims to address this by comprehensively charting human and animal models to identify patterns of immunomodulatory and anti-inflammatory effects of SLO and its bioactive components, thus highlighting areas requiring further investigation. A scoping search through Cochrane, PubMed^®, MEDLINE^® via Ovid and Scopus using keywords such as \"shark liver oil\", \"immunomodulation\", \"anti-inflammatory\", similar keywords and their combinations was performed.
