lespedeza davurica/抗氧化剂

The stems of Lespedeza homoloba yielded fifteen new isoflavonoids and a new stilbenoid having antioxidative activity. Their structures were determined by analysis of spectroscopic evidence.

The stems of Lespedeza homoloba yielded eight new and three known phenolic compounds. Their structures have been elucidated on the basis of their spectral data. These compounds had strong antioxidative activity against lipid peroxidation in the rat brain homogenate test. 3,9-Dihydroxypterocarp-6a-en

Lespedeza cuneata G. Don is a traditional herb that has been associated with multiple biological activities. In this study, we investigated the antioxidative/antiaging activities and performed an active component analysis of the non-fermented and fermented (using Lactobacillus pentosus) extracts of

Although tannin-rich forages are known to increase protein uptake and to reduce gastrointestinal nematode infections in grazing ruminants, most published research involves forages with condensed tannins (CT), while published literature lacks information on the anthelmintic capacity, nutritional

Bioactivity guided fractionation of the ethanolic extract of the whole plants of Lespedeza virgata (Thunb.) DC. resulted in the isolation of a novel flavonoid (1) along with five known compounds 2-6. The molecular and structural formula as well as the stereochemistry of compound 1 were determined

Two 2-phenylbenzofurans, lespedezavirgatol (1) and lespedezavirgatal (2), and a coumestan, lespedezacoumestan (3), were isolated from the aerial parts of Lespedeza virgata, together with nine known flavonoids. Their structures were determined on the basis of spectroscopic data. The three new

Four new pterocarpans (6aR,11aR)-6a,11a-dihydrolespedezol A₂ (2), (6aR,11aR)-2-isoprenyl-6a,11a-dihydrolespedezol A₂ (3), (6aR,11aR,3'R)-6a,11a-dihydrolespedezol A₃ (4), (6aR,11aR,3'S)-6a,11a-dihydrolespedezol A₃ (5) and one new stilbenoid with

Postinflammatory hyperpigmentation (PIH) is an acquire hypermelanosis after cutaneous inflammation and injury. The aim of the present study was to investigate a natural ingredient with the anti-inflammatory and depigmentation activities into possible applications of postinflammatory

The present investigation was aimed to scrutinize the salt tolerance potential of plant-growth-promoting rhizobacteria (PGPR) isolated from rhizospheric soil of selected halophytes (Atriplex leucoclada, Haloxylon salicornicum, Lespedeza bicolor, Suaeda fruticosa, and Salicornica virginica) collected
