(2) Black bindweed seed (Polygonum convolvulus) from the 1987 harvest was tested for possible toxicity in a 38-day range-finding test with Wistar rats which received feed rations on the basis of VDT-1 standard feedstuff and components of 5 or 20%.
(3) The petroleum ether, alcoholic, and aqueous extracts of 5 indigenous plants, known to have antifertility activity in female rats and mice (Areca catechu Linn, Carica papaya Linn, Daucus carota Linn, Mentha arvensis Linn and polygonum hydropiper Linn), were evaluated for their possible antiovulatory activity in rabbits with copper-induced ovulation.
(4) The mechanism of antimutagenicity of water extracts of grass-wrack pondweed (Potamogeton oxyphylus Miquel), curled pondweed (Potamogeton crispus L.) and smartweed (Polygonum hydropiper L.) towards benzo[a]pyrene mutagenicity in Salmonella typhimurium was investigated.
(5) Emodin and scoparone, the active principles isolated from Polygonum multiflorum and Artemisia scoparia, respectively, both exhibit vasorelaxant and immunosuppressive effects.
(6) Bulbils of Polygonum viviparum L. were a good source of metabolizable energy, protein and phosphorus, but were deficient in sodium.
(7) The number of adhesive WBC was decreased by 80%, the amount of open capillary returned to near normal, and the aggregation of WBC and the degree of tissue damage in the lung were alleviated by administration of crystal No 4 of Polygonum cuspidatum.
(8) This paper reports the assay of stilbene glucoside in the root of Polygonum multiflorum and its two processed products by first derivative spectrophotometry.
(9) We studied cellular resistance to copper of plant cells Polygonum cuspidatum.
(10) It can be used for the quality control of processing Polygonum multiflorum.
(11) made of thirteen herbs: Polygonum multiflorum, Codonopsis silvestris, Astragalus membranaceus, Poria cocos, etc.)
(12) The herbs Rheum palmatum B and Polygonum cuspidatum S are frequently used as laxatives and anticancer drugs in Chinese medicine.
(13) Using L. natalensis as the target snail, it was shown that the freeze dried material was more potent than the freeze-dried berries of S. incanum, S. nigrum or leaves of Polygonum senegalensis (Family Polygonaceae), all present in Kenya, and known to possess molluscicidal properties.
(14) Five extracts were not active but extracts of Balanites aegytiaca, Blighia sapida, Boswellia dalzielii, Cissampelos mucronata, Detarium microcarpum, Kigelia africana, Opilia celtidifolia, Parkia clappertoniana, Polygonum limbatum, Pseudocedrela kotschyi, Nauclea latifolia and Securidaca longipedunculata were molluscacidal.
(16) In 15 of these families the hypostase is present together with the Polygonum type of embryonic sac and nuclear type of endosperm.
(17) The root of Polygonum multiflorum and its processed products also reduced the enlargement of liver by CCl4.
(18) The herbal composition included Achillea millefolium, Urtica dioica, Cichorium (aboveground part), Polygonum, Matricaria chamomilla (flowers), Helichrysum arenarium, Calendula (flowers), corn stigmas, Humulus lupulus (racemes) in proportion 3:3:1:1:2:1:1:2:1 respectively.
(19) This paper reports the qualitative analysis and content determination of phospholipids in the crude drug of Polygonum multiflorum and its four processed products by TLC.
(20) The alcoholic extract of Mentha arvensis (leaves) and the petroleum ether extract of the roots of Polygonum hydropiper were the most successful agents, inhibiting ovulation in 60% of the animals.
