Brassinosteroids are a class of naturally occur­ ring phytohormones with high biological activity found in a wide variety of higher plants (Adam and Petzold, 1994; Adam et al., 1996; Cutler et al., 1991; Sakurai and Fujioka, 1993). Brassinosteroids occur only in trace amount (ngto ^ig/kg plant material). Therefore, their purification has to be monitored by a sensitive bioassay (Wada et al., 198...

-Air pollution tolerance index (APTI) is used by landscapers to select plant species tolerant to air pollution. Four physiological and biochemical parameters including leaf relative water content (RWC), ascorbic acid (AA) content, total leaf chlorophyll (TCh), and leaf extract pH were used to develop an APTI. Twenty-three plant species growing near a Beijing steel factory, an air pollution poin...

This study aimed to determine the total antioxidant capacity of the essential oil (EO) of leaves of Bidens pilosa (Linn. Var. Radita) used as protectant of stored grains in Northern Cameroon. EO was characterized by GC-FID, antioxidant activity (AA) was determined by combining: evaluation of radical-scavenging activity, reducing power (RP) and co-oxidation of β-carotene methods. Tests were carr...

Currently multiresistant Staphylococcus aureus is one common cause of infections with high rates of morbidity and mortality worldwide, which directs scientific endeavors in search for novel antimicrobials. In this study, nine extracts from Bidens pilosa (root, stem, flower and leaves) and Annona crassiflora (rind fruit, stem, leaves, seed and pulp) were obtained with ethanol: water (7:3, v/v) a...

We evaluated the in vitro and in vivo inhibition of S180 tumor cell growth of the water extract of Agrimonia pilosa. Inhibitory effect of Agrimonia pilosa on in vitro-cultured S180 cell proliferation was measured by MTT assay; mice model of transplanted tumor was established, after 8 days of continuous administration, the tumors were removed, weighed, and compared with the control group, and th...

To clarify the substantial basis of the excellent antioxidant capacity of Agrimonia pilosa Ledeb. Fourteen flavonoids were isolated and identified from Agrimonia pilosa Ledeb, seven of which have notable DPPH radical scavenging activities, i.e., catechin, luteolin, quercetin, quercitrin, hyperoside, rutin, luteolin-7-O-β-glucoside with IC50 values of 5.06, 7.29, 4.36, 7.12, 6.34, 6.36 and 8.12 ...

In the interests of food safety and public health, plants and their compounds are now re-emerging as an alternative approach to treat gastrointestinal diseases in chickens. Here, we studied the impact of the edible medicinal plant, B. pilosa, on growth performance, gut bacteria and coccidiosis in chickens. First, we found that B. pilosa significantly elevated body weight gain and lowered feed c...

s: It had been demonstrated that Glycyrrhiza glabra extract has biological beneficial impacts include anti-inflammatory as well as anti-allergic properties, although there is little published data about its probable side effects on the placental integrity. Since, there is not enough data regarding the impacts of G. glabra on the placental histo-morphology. Therefore, this study was carried out ...

Atherosclerosis which results from gradual deposition of lipids in medium and large arteries is a leading cause of mortality worldwide. Glycyrrhiza glabra is an herb of Fabacea family which contain hypolipidemic compounds and flavonoids with high antioxidative properties. This study was conducted to determine the effect of Glycyrrhiza glabra extract on blood lipids and atherosclerosis in rabbit...
