Extraction optimization, structural characterization and potential alleviation of hyperuricemia by flavone glycosides from celery seeds
Food Funct 2022 Oct 3;13(19):9832-9846.PMID:36047466DOI:10.1039/d2fo01715f.
Celery seeds are commonly used as condiments and in herbal teas with high medicinal value. In the present study, we investigated the contents of extracts derived under different extraction conditions and determined the optimal conditions for only extracting flavone glycosides from celery seeds. The compositional analysis identified three primary flavone glycosides in the ethanolic extract, and apiin, Graveobioside A, and graveobioside B were isolated. Apigenin, luteolin, and chrsyeriol were obtained by the acid hydrolysis of flavone glycosides under high-temperature conditions. Here we investigated the inhibitory activity of apigenin and apiin on xanthine oxidase by reducing the rate of oxidative cytochrome C and found that both apigenin and apiin reduced cytochrome C production, except for low concentrations of apiin. In vivo analysis with hyperuricemia mice and rats showed that apiin had excellent uric acid-lowering effects and high dose-dependence, while apigenin was relatively slightly uric acid-lowering. In addition, the flavone glycoside extracts from celery seeds exhibited similar effects of reducing uric acid with apiin. Surprisingly, in hyperuricemia rats, the uric acid-lowering effects of high-dose apiin and flavone glycoside extracts were almost comparable to that of allopurinol. Besides, our experimental results showed that apigenin could improve uric acid clearance by increasing the glomerular filtration capacity, which was reflected in reducing the renal function parameters SUN and SCr; also, apiin showed better results. This study also showed that celery seeds have a unique medicinal value in treating hyperuricemia and that the flavone glycoside extracts from celery seeds can be developed as medicine for hyperuricemia.
Impact of Moderate Cold and Salt Stress on the Accumulation of Antioxidant Flavonoids in the Leaves of Two Capsicum Cultivars
J Agric Food Chem 2021 Jun 16;69(23):6431-6443.PMID:34081868DOI:10.1021/acs.jafc.1c00908.
The horticultural production of bell peppers generates large quantities of residual biomass. Abiotic stress stimulates the production of protective flavonoids, so the deliberate application of stress to the plants after fruit harvest could provide a strategy to valorize horticultural residuals by increasing flavonoid concentrations, facilitating their industrial extraction. Here we exposed two Capsicum cultivars, a chilli and a bell pepper, to cold and salt stress and combinations thereof to determine their valorization potential. Noninvasive image-based phenotyping and multiparametric fluorescence measurements indicated that all stress treatments inhibited plant growth and reduced the leaf chlorophyll fluorescence index, with the chilli cultivar showing greater sensitivity. The fluorescence-based FLAV index allowed the noninvasive assessment of foliar luteolin glycosides. High-performance liquid chromatography-mass spectrometry (HPLC-MS) analysis showed that moderate cold increased the levels of two foliar antioxidant luteolin glycosides in both cultivars, with bell pepper containing the highest amounts (induced to maximum 5.5 mg g-1 DW cynaroside and 37.0 mg g-1 DW Graveobioside A) after combined stress treatment. These data confirm the potential of abiotic stress for the valorization of residual leaf biomass to enhance the industrial extraction of antioxidant and bioactive flavonoids.
