preliminary study of sex hormones of medical importance in bangladeshi plants.	twenty six different bangladeshi plants of folkloric contraceptive use were screened for their oil content, percent unsaponifiables and steroids particularly estradiol, and estrogenic steroids. the distribution of these parameters were studied in seeds, roots, leaves, barks and whole plants. the oil content ranged between 0.23 and 6.75% being highest in jasminium sacbac (family : oleaceae) seeds. the unsaponifiables varied from 0.04 to 7.87% showing highest content in xanthium stamanium (roots), ...	1978	757346
antiinflammatory activity of some medicinal plant extracts form venezuela.	six medicinal plant extracts from venezuela, used in traditional medicine, were investigated for their anti-inflammatory potential against adjuvant-carrageenan-induced inflammation (acii). all doses expressed here are equivalents of dried starting plant materials (1.50 g dry plant/kg body wt.). the most interesting plant extracts were synedrella nodiflora, and the hexane leaf extract of bursera simaruba. in acii, orally administered extracts (at doses 40 and 80 mg/kg, respectively), inhibited bo ...	1996	9121169
insecticidal and vertebrate toxicity associated with ethnobotanicals used as post-harvest protectants in ghana.	six plant species (cassia sophera, chamaecrista nigricans, mitragyna inermis, ocimum americanum, securidaca longepedunculata and synedrella nodiflora) traditionally used in ghana to control insect pests of stored grain and legumes were screened in the laboratory at three concentrations (0.5, 1 and 5%, w/w) against four common storage pests (rhyzopertha dominica, callosobruchus maculatus, sitophilus zeamais and prostephanus truncatus). all the plants showed some ability to control all or some of ...	2001	11278061
dimorphic cypsela germination and plant growth in synedrella nodiflora (l.) gaertn. (asteraceae).	synedrella nodiflora is a weed species that has dimorphic cypselas: winged peripheral and lanceolate shaped central. the aim of this work is to describe the reproductive capability by measuring dimorphic cypselas morphology, imbibition rates and germinative patterns under temperature, light quality and water availability gradients, and compare the plant growth between two light treatments. the central cypselas were lighter, longer and its pappi were more elongated than the peripheral ones, favor ...	2011	21755175
antibacterial and antioxidant activities of synedrella nodiflora (l.) gaertn. (asteraceae).	the hexane, ethyl acetate, ethanol and water extracts of synedrella nodiflora (l.) gaertn. (asteraceae) were assessed for their antibacterial and antioxidant capacities. the antioxidant capacities were evaluated using the ferric reducing antioxidant power (frap) and β-carotene bleaching assays. the antimicrobial activities were assessed using the classical pour-plate disc diffusion, minimum inhibitory concentration (mic), minimum bactericidal concentration (mbc) and death kinetic assays, against ...	2011	22754934
tri-trophic insecticidal effects of african plants against cabbage pests.	botanical insecticides are increasingly attracting research attention as they offer novel modes of action that may provide effective control of pests that have already developed resistance to conventional insecticides. they potentially offer cost-effective pest control to smallholder farmers in developing countries if highly active extracts can be prepared simply from readily available plants. field cage and open field experiments were conducted to evaluate the insecticidal potential of nine com ...	2013	24205287
