A new selaginellin named selaginellin O (1), along with three other known selaginellins (2-4) were isolated from Selaginella tamariscina (Beauv.) Spring. On the basis of spectroscopic analysis, the structure of selaginellin O was demonstrated to be
Sulfurous springs have been traditionally used in medical treatment for different purposes. These beneficial effects of sulfurous water have been attributed to the presence of sulfurous compounds mainly in the form of hydrogen sulfide (H2S). The purpose of the present study is to explore
High temperature is one of the important stress factors that affect crops in tropical countries. Plants do evolve or adopt different mechanisms to overcome such stress for survival. It is an interesting subject and has attracted many researchers to work upon. Here, we studied the effect of salicylic
BACKGROUND
Northward expansion of winter wheat is an efficient means to improve crop yield and quality in many countries. However, inadequate cold hardiness restricts the northward expansion of winter wheat. This study aimed to investigate cold adaption of different wheat varieties and underlying
A new antioxidant, designated pyranonigrin L, was isolated from the culture materials of the hot spring-derived fungus Penicillium adainetzii BF0003 by solvent extraction, ODS column chromatography, and HPLC. Its planar structure was elucidated using various analytical techniques including UV, IR,
Zeaxanthin is a powerful antioxidant that is widely found in vegetables and fruits. Epidemiological evidences suggest that increasing the consumption of zeaxanthin in the diet is associated with a lower risk of age-related macular degeneration, helps prevent glaucoma and cataracts, and supports
OBJECTIVE
To investigate the antidiabetic, antihyperlipidaemic and antioxidant activity of total flavonoids in Selaginella tamariscina (Beauv.) Spring (TFST) in a mouse model of diabetes.
METHODS
Normal mice, mice fed with a high-fat emulsion diet and streptozotocin (STZ)-induced diabetic mice were
The health-promoting effects of whole-grain wheat likely derive from phenolic compounds and other antioxidants that also make wheat a potential source of functional food ingredients. The objective of this study was to determine the effects of genotype and growing environment on the phenolic contents
Different defense mechanisms of three spring wheat (Triticum aestivum L.) varieties were studied by withholding watering in well-watered pots to gradually increase water deficit of plants grown in containers. The strategies of plant adaptation were divided into three phases according to the severity
Seasonal variations in temperature may influence the physiological and pathological metabolic pathways, concentrations of antioxidants, degree of oxidative stress and mitochondrial function. The aim of this study was to evaluate platelet mitochondrial function in human subjects during seasonal
Heat stress (HS) is a worldwide threat to productivity of wheat, especially in arid and semiarid regions of the world. Earlier studies suggested the beneficial effects of selenium (Se) on the growth of some crop species grown under stressful environments. In the present study, we assessed whether Se
This research was to determine the effect of foliar application of selenium on increasing the antioxidant activity of tea harvested during the early spring tea producing season using a alpha,alpha-diphenyl-beta-picrylhydrazyl (DPPH) radical scavenging method and the linoleic acid system. The results
Two modern fungicides, a strobilurin, azoxystrobin (AZO), and a triazole, epoxiconazole (EPO), applied as foliar spray on spring barley (Hordeum vulgare L. cv. Scarlett) 3 days prior to fumigation with injurious doses of ozone (150-250 ppb; 5 days; 7 h/day) induced a 50-60% protection against ozone
Spring viremia of carp virus (SVCV) causes devastating losses in aquaculture. Coumarin has an advantageous structure for the design of novel antiviral agents with high affinity and specificity. In this study, we evaluated a hydroxycoumarin medicine, i.e., 7-(6-benzimidazole) coumarin (C10),
In barley endosperm arabinoxylan (AX) is the second most abundant cell wall polysaccharide and in wheat it is the most abundant polysaccharide in the starchy endosperm walls of the grain. AX is one of the main contributors to grain dietary fibre content providing several health benefits including
