chinese jujube (ziziphus jujuba mill.) has long been widely used for human consumption and medicinal purposes in china. it has been reported to possess several vital biological activities. however, the systematic study on the chemical constituents absorbed into plasma and their metabolites is still insufficient. a high-performance liquid chromatography-photodiode array detector-electrospray ion...

introduction: walnut leaf contains large amounts of antioxidants, phenolic compounds and flavonoids and the beneficial effect of these compounds in the treatment of diabetes has been shown. this study investigated the effect of cyclohexane and ethanol extract of walnut leaf on activity of sorbitol dehydrogenase (sdh) enzyme. methods: fifty- six adult male sprague-dawley rats were divided into s...

ABSTRACT The main goal was to optimize and establish the kinetics thermodynamics of extraction process. An investigation into effects ethanol concentration (0-100 %), liquid solid ratio (30-60 mL g-1), temperature (25-65 °C), time (40-200 min) on total phenols (TP) flavonoids (TF) from linden (Tilia cordata M.) flowers performed using single-factor experiments. Experimental results showed that ...

chronic ethanol consumption leads to oxidative stress in the heart and erythrocytes of rats. as ziziphus jujuba fruit has been shown to have potent antioxidants, such as flavonoids, we conducted this study to evaluate the effects of aqueous fruit extracts from z. jujuba on rat hearts and erythrocytes following chronic ethanol consumption. twenty-eight male wistar rats were randomly divided into...

the β2-adrenergic effects of macerated extract, aqueous extract, ethanol extract, and essential oil of carum copticum, 5 nm propranolol, and saline were tested by performing cumulative log concentration-response curves of isoprenaline-induced relaxation of precontracted isolated guinea pig tracheal chains in three different conditions including: non-incubated (group 1, n=9) incubated with 1 µm ...

background: saffron is the dried stigmata of the flowers of saffron (crocus sativus l., iridaceae). saffron is well known for the treatment of gastric disorders in traditional medicine.   objectives: in the search for new potential antiulcer agents, the effects of the ethanol extract of saffron and its active constituents crocin and safranal as compared with omeprazole against gastric ulcer ind...

Flavonoids and phenolics are abundant in loquat flowers. Methanol had the highest extraction efficiency among five solvents, followed by ethanol. Considering the safety and residue, ethanol is better as extraction solvent. The average content of flavonoids and phenolics of loquat flower of five cultivars were 1.59 ± 0.24 and 7.86 ± 0.87 mg/g DW, respectively, when using ethanol as extraction so...

the present study was designed to assess the cytotoxicity, anti-inflammatory and analgesic properties of methanol extract of woodfordia fruticosa flowers. cytotoxic activity of methanol extract of woodfordia fruticosa flowers was tested using artemia salina (brine shrimp) bioassay. two doses (400 and 600 mg/kg) were evaluated for the anti-inflammatory activity against the carrageenan, histamine...

Consumption of the edible flowers forms new trend in human nutrition, especially in Bulgaria. Therefore, the determination of bioactive compounds content in their petals presents important tasks for their evaluation as natural source of antioxidants for human diet. In this study the quantity of natural pigments, total phenolic content and total flavonoids content, as well the antioxidant capaci...
