nauclea pobeguinii/silica

OBJECTIVE To investigate the chemical constituents of Nauclea latifolia, which is an African folk medicine and collected from Guinea. METHODS The chemical constituents were isolated by silica gel and Sephadex LH-20 column chromatographies, and structurally elucidated by spectral evidence together

In order to study the chemical constituents in the water extract of the stem of Nauclea officinalis, column chromatography over D101 macroporous resin and silica gel and an automatic purification system were used to isolate and purify the chemical constituents from the extract. Nine compounds were

OBJECTIVE To investigate the chemical constituents of water-soluble part of stem of Nauclea officinalis. METHODS The compounds were isolated and purified by resins, silica gel, and Sephadex LH20 column chromatography repeatedly, and their structures were identified by spectral

This study is a first-hand report of the immobilization of Nauclea diderrichii seed waste biomass (ND) (an agro-waste) with eco-friendly mesoporous silica (MS) and graphene oxide-MS (GO + MS) nanoparticles, producing two new hybrid materials namely: MND adsorbent for agro-waste modified with MS and
