This study was designed to evaluate the therapeutic effect of 70% ethanolic crude extract of Portulaca oleracea L on mice mammary adenocarcinoma (in vivo). In vivo, the acute toxicity of 70 % ethanolic extract of the plant on normal mice has been studied. No toxic effect was noticed on normal mice even at 9500 mg /kg B.W S/C injection. Therapeutic effect of ethanolic extract of Portulaca olerac...

OBJECTIVE To identify anti-hypoxia ingredients extracted from Portulaca oleracea and to find out the possible mechanism of its anti-hypoxia actions. METHODS Seventy mice were randomly divided into seven groups which were untreated (normal saline), ginsenosides-treated, polysaccharide-treated, acidic components-treated, basic components-treated, alkaloids-treated and flavones-treated groups, a...

The choice of leaf-killing technique was found to affect significantly the distribution of label among early labeled photosynthetic products in two C(4) plants, Portulaca oleracea and Zea mays. The major effect of these procedures was on the amount of amino acids present, particularly alanine, and the ratio of malate to aspartate. Killing Portulaca leaves in alcohol generally results in more al...

BACKGROUND Portulaca oleracea Linn. (Portulacaceae) is commonly known as purslane in English. In traditional system it is used to cure diarrhea, dysentery, leprosy, ulcers, asthma, and piles, reduce small tumors and inflammations. AIM To assess cytotoxic potential of chloroform extract of P. oleracea whole plant against human colon adenocarcinoma (HCT-15) and normal (Vero) cell line. MATERI...

Portulaca oleracea L. has been used as a food and medicinal plant for thousands of years in China. Polysaccharides extracted from P. oleracea L. (POP) are its main bioactive compound and have multiple pharmacological activities. However, anti-fatigue effects of POP have not yet been tested. This study was designed to investigate the anti-fatigue effects of POP in mice using the rotarod and forc...

Soil in laboratory microcosm experiments was amended with dried and milled crop residue of onion (Allium cepa L. cv. Mission) or garlic (A. sativa L. cv. California Early). The amend ments, along with the additional factors of amendment concentration (0, 1 or 3% (w/w)) an soil temperature (23 or 39 8C), were evaluated with respect to germination of seeds of th weedy annual plants Echinochloa cr...
