Isolation and identification of euphol and β-sitosterol from the dichloromethane extracts of Synadenium glaucescens
(2016-06) Nyigo, Vitus A; Peter, Xolani; Fouche, Gerda; Mabiki, Faith; Malebo, Hamisi M; Mdegela, Robinson H
Purification of dichloromethane extract from root barks and leaves of Synadenium glaucescens respectively resulted into the isolation of two compounds namely Euphol and β -sitosterol. Chemical structures were established mainly by using 1 H an d 13 C NM R data and by comparing current NMR data with those reported in the literature. Both compounds are known and have been isolated from other plant species but are being reported from this plant species for the first time.
Isolation and identification of long -chain aliphatic compounds from synadenium glaucescens
(The Journal of Phytopharmacology, 2022) Nyigo, Vitus A; Malebo, Hamisi M; Mabiki, Faith; Mdegela, Robinson
Purification of dichloromethane extract from root barks and leaves of Synadenium glaucescens extracts through chromatographic techniques resulted into the isolation of two compounds, namely erythrinacinate C and 1-octacosanol. Chemical structures were established mainly using both one and two dimensional 1H and 13C NMR data and by comparison of the current NMR data with those from literature. Mass spectrophotometry data were used for confirmation through molecular ion peak. Both compounds are known to have been isolated from other plant species but are being reported from this plant species for the first time.
