Food Chem 2024; 459:140431.

Abstract
Insight investigation on both edible pulps and inedible parts involving inflorescence axis and shreds of Artocarpus heterophyllus Lam were carried out, a total of 98 VOCs and 201 masses were identified by the combination of HS-SPME-GC-MS and PTR-TOF-MS. Among them, according to the consistency of OAV and results of VIP > 1, p < 0.05, compounds methyl isovalerate (A2), 3-methylbutyl acetate (A5) and octanoic acid, ethyl ester (A21) were recognized as aroma markers to distinguish the pulps, shreds and inflorescence axis. Meanwhile, the inflorescence axis (IC50: 1.82 mg/mL) and shreds (IC50: 16.74 mg/mL) exhibited more excellent antioxidant potency than pulps (IC50: 17.43 mg/mL) in vitro. These findings validated the feasibility of coupling HS-SPME-GC-MS and PTR-TOF-MS for rapid detection of characteristic VOCs of this plant, and offered new prospect of fragrance utilization and waste management of the edible and inedible parts of A. heterophyllus fruit.

Front Pharmacol 2022; 13:1004520. [PMID: 36238556 PMCID: PMC9552299 DOI: 10.3389/fphar.2022.1004520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 08/18/2022] [Indexed: 11/28/2022] Open
Abstract
Chimonanthi Praecocis Flos, namely wintersweet flower, is the edible flower or flower bud of Chimonanthus praecox (L.) Link which is a deciduous shrub plant originated from China and is widely cultivated as a garden or ornamental plant all over the world. However, few studies focused on its anti-inflammatory property. In the present study, we explored the anti-inflammatory and anti-oxidative activities of ethanol extract of Chimonanthi Praecocis Flos (CPE) which contained 7.980% ± 0.176% total flavonoids and 1.461% ± 0.041% total alkaloids. In LPS-stimulated RAW264.7 macrophages, CPE significantly decreased the production of NO and prostaglandin E2 (PGE2) through reducing the expressions of their synthases—inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). It also suppressed the transcription and translation of pro-inflammatory cytokines interleukin-1β (IL-1β) and interleukin-6 (IL-6). Further research revealed that CPE impeded the phosphorylation and degradation of IκBα, thus restraining the nuclear translocation of p65, and consequently dampening NF-κB signaling. In endotoxemia mice, several pro-inflammatory cytokines in serum were also decreased after CPE treatment. Besides anti-inflammatory activity, anti-oxidative activity is another important capacity of wintersweet flower. Indeed, CPE reduced LPS-elevated intracellular total reactive oxygen species (ROS) level by weakening NADPH oxidase activity in cell system. Moreover, it directly scavenged DPPH radical and superoxide anion, and exerted ferric reducing ability in cell-free system. Our findings demonstrate that wintersweet flower can be used as a beneficial natural product or an additive by virtue of its anti-oxidative and anti-inflammatory properties.

Content and composition analysis of polysaccharides from Blaps rynchopetera and its macrophage phagocytic activity. OPEN CHEM 2021.

Abstract
Abstract
Blaps rynchopetera Fairmaire has a long history of use as a folk medicine in China for treating fever, cough, gastritis, boils, and tumors. In the present study, the content analyses, monosaccharide composition analyses, and the macrophage phagocytic activity of rynchopetera polysaccharides (RPS) were reported. B. rhynchoptera is rich in polysaccharides (content value 3.97%). Through PMP (1-phenyl-3-methyl-5-pyrazolone) pre-column derivatization and high performance liquid chromatography (HPLC) testing, the results showed that RPS consist of 8 known monosaccharides, including D-mannose (Man), Rhamnose (Rha), D-glucuronic acid (GlcUA), D-galacturonic acid (GalUA), D-glucose (Glc), D-galactose (Gal), Arabinose (Ara), and Fucose (Fuc), with the total content of 171.70 mg g−1 and Glc has the highest content of 45.40 mg g−1. The phagocytic ability of mouse peritoneal macrophages was investigated after RPS stimulating alone and combined with lipopolysaccharide (LPS). RPS played an important role in the engulfment of mouse peritoneal macrophages and can significantly enhance the phagocytic ability of macrophages. However, no synergistic effects were observed when RPS combined with LPS.
