| antiviral effects of dihydroxypropyladenine [rs)-dhpa) and bromovinyldeoxyuridine (bvdu) on plant viruses. | two established antiviral agents, dihydroxypropyladenine (rs)-dhpa and bromovinyldeoxyuridine (bvdu) were evaluated for their inhibitory effects on 4 plant viruses: tobacco mosaic virus, potato virus x (pvx), eggplant mosaic virus (emv) and a potyvirus isolated from solanum palinacanthum (poty-sp). using the leaf disc incubation test, bvdu proved virtually inactive while (rs)-dhpa efficiently inhibited emv and poty-sp when applied at concentrations as low as 5 mg/l. tmv was less susceptible to t ... | 1987 | 3446016 |
| identification of the antimicrobial substances produced by solanum palinacanthum (solanaceae). | to find out natural antimicrobial agents as alternative in therapeutics and to preserve food, the methanol extract of solanum palinacanthum aerial parts was submitted to purification steps guided by antibacterial and antifungal assays. as a consequence, the flavonoid rutin and 3,5-dicaffeoylquinic acid were isolated by column chromatography and high performance liquid chromatography, and identified by mass and nuclear magnetic resonance spectrometry. minimal inhibitory concentrations (mic) of th ... | 2008 | 18797795 |
| in vitro trypanocidal activity of solamargine and extracts from solanum palinacanthum and solanum lycocarpum of brazilian cerrado. | the present investigation was to evaluate the potential trypanocidal activity of crude ethanolic extract of the fruits of solanum palinacanthum, solanum lycocarpum and the glycoalcaloid, solamargine. s. palinacanthum and s. lycocarpum fruit powders were submitted to exhaustively extraction with 96% ethanol and solamargine were isolated from the extract of s. palinacanthum. both extracts and solamargine were analysed for trypanocidal activity by using mtt colorimetric assay. extracts of s. palina ... | 2013 | 24068082 |
