Hibiscus sabdariffa has gained attention for its antioxidant activity. There are many accessions of H. sabdariffa in the world. However, information on the quantification of antioxidant compounds in different accessions is rather limited. In this paper, a liquid chromatography/quadrupole-time-of-flight mass spectrometry (LC-Q-TOF-MS) method for simultaneous determination of five antioxidant com...
The aim of this study was the evaluation of the antioxidant capacity of Cotoneaster melanocarpus Lodd. and the identification of antioxidant active constituents of this plant. C. melanocarpus Lodd. is a shrub indigenous to Mongolia and used in Traditional Mongolian Medicine as a styptic. Before extraction, the plant material was separated into three parts: young sterile shoots, older stems and ...
In the present study, we investigated the variation in the content of naphthodianthrones hypericin and pseudohypericin, phloroglucinol derivatives hyperforin and adhyperforin, the phenolic acids as chlorogenic acid, neochlorogenic acid, 2,4-dihydroxybenzoic acid, and the flavonols, namely, hyperoside, isoquercitrin, quercitrin, quercetin, avicularin, rutin, (+)-catechin and (-)-epicatechin, and...
Stauntonia hexaphylla (Thunb.) Decne. (Lardizabalaceae) leaves (SHL) have been used traditionally as analgesics, sedatives, diuretics, and so on, in China. To date, no data have been reported on the inhibitory effect of SHL and its constituents on rat lens aldose reductase (RLAR) and advanced glycation end products (AGEs). Therefore, the inhibitory effect of compounds isolated from SHL extract ...
The anthocyanin composition and HPLC fingerprints of six small berries endemic of the VIII region of Chile were investigated using high resolution mass analysis for the first time (HR-ToF-ESI-MS). The antioxidant features of the six endemic species were compared, including a variety of blueberries which is one of the most commercially significant berry crops in Chile. The anthocyanin fingerprin...
The fruit of Stauntoniahexaphylla is commonly used as a traditional anthelmintic in Korea, Japan, and China. However, its anti-inflammatory activity and the underlying mechanisms have not been studied systematically. In the present study, we examined the anti-inflammatory activities of an aqueous extract of S. hexaphylla fruit (SHF) in lipopolysaccharide (LPS)-activated RAW 264.7 cells. The SHF...
Berries of three Romanian Lonicera caerulea cultivars ‘Cera’, ‘Kami’, and ‘Loni’, grown at the Research Institute for Fruit Growing, Pitesti, Romania, were analyzed between 2020 2022 in terms chemical composition. The study aimed to determine concentrations some compounds with antioxidant activity, highlight most valuable cultivar, encourage consumption honeysuckle berries, indirectly stimulate...
BACKGROUND Ten genotypes representing two elderberry species, Sambucus canadensis L. (eight genotypes) and S. nigra L. (two genotypes), were examined for their anthocyanins (ACY), total phenolics (TP),°Brix, titratable acidity (TA), and pH over two growing seasons. RESULTS Overall, fruit generally had higher ACY, TP, ACY/TP,°Brix, and pH in 2005 than 2004. All samples of S. canadensis had sim...
In this study, the effects of mixed silage on fermentation quality, chemical composition and bacterial communities corn straw soybean were assessed. Corn straws, straws or a mixture in 1:1 mass ratio uniformly processed using same method to produce bagged weighing 50 kg per bag. At days 0, 14 60 process, nutritional quality indicators each group measured. A complete factorial design assess effe...
ReDuNing injection, prepared from a combination of Gardenia Jasminoides fruits, Lonicera japonica flower buds, and the Artemisia annua aerial part, is extensively used for treatment of viral upper respiratory tract infections in China. Iridoids, organic acids, and flavonoids are likely important compounds of the herbal injection because of their reported pharmacological properties. This study w...
