| radical scavenging activity of selected medicinal plants from limpopo province of south africa. | plants collected from limpopo province of south africa were investigated for their antioxidative potential using the dpph radical scavenging assay. acetone extracts of flueggea virosa had the highest antioxidant activity with an ic₅₀ value of 30 µg/ml, closely matching the ascorbic acid with an ic₅₀ value of 25 µg/ml. the lowest antioxidant readings were observed with extracts of rhynchosia venulosa (root extract) and ficus ingens (leaf extract). acetone extract of bridelia virosa leaves had the ... | 2012 | 23983377 |
| quantitative analysis of biomarker rutin in different species of genus ficus by validated np and rp-hptlc methods. | biomarker rutin was analyzed in methanol extracts of leaves of five different species of genus ficus (ficus carica, ficus nitida, ficus ingens, ficus palmata and ficus vasta) by np-hptlc (method i) and rp- hptlc methods (method ii). the development and validation for method i was carried out with silica gel 60f254 plates using ea: gaa: fa: h2o (10:1:1:2.5, v/v/v/v) as developing system. method ii was carried out on silica gel 60f254 rp-18 plates using mobile phase acn: h2o (4:6 v/v). both analys ... | 2015 | 26687740 |
| in vitro antiplasmodial, antileishmanial and antitrypanosomal activities of selected medicinal plants used in the traditional arabian peninsular region. | worldwide particularly in developing countries, a large proportion of the population is at risk for tropical parasitic diseases. several medicinal plants are still used traditionally against protozoal infections in yemen and saudi arabia. thus the present study investigated the in vitro antiprotozoal activity of twenty-five plants collected from the arabian peninsula. | 2012 | 22520595 |
| a nervous disorder in cattle, caused by the plants ficus ingens var. ingens and ficus cordata subsp. salicifolia. | two outbreaks of neurotoxicoses are reported in cattle browsing on the leaves of ficus spp. in the first outbreak, three animals died and one became ill. a sheep developed severe nervous signs, including tetanic spasms, when dosed with the leaves of ficus ingens var. ingens from the toxic camp where the cattle had died. the second outbreak resulted in the death of 12 heifers within 48 h of ingestion of the leaves of f. cordata subsp. salicifolia. clinical signs included hyperaesthesia, ataxia, m ... | 1994 | 7596567 |
| mating ecology of the nonpollinating fig wasps of ficus ingens. | the males of many fig wasps fight fatally for mating opportunities. the concentration of females in space has been proposed as one factor selecting for their aggressive behaviour. we studied the temporal distribution of receptive females to obtain a clearer impression of the operational sex ratio in figs. females of nonpollinating species emerged from figs over a protracted period of time and this resulted in an extremely male-biased operational sex ratio, conducive to extreme fighting. since th ... | 1999 | 10053089 |
