A pregnane glycoside and a lignan glycoside were isolated from the aerial parts of Rubus amabilis. Their structures were elucidated as 3-O-beta-D-glucopyranosyl-3 beta.15 alpha-dihydroxypregn-5-en-20-one and (-)-secoi...A pregnane glycoside and a lignan glycoside were isolated from the aerial parts of Rubus amabilis. Their structures were elucidated as 3-O-beta-D-glucopyranosyl-3 beta.15 alpha-dihydroxypregn-5-en-20-one and (-)-secoisolariciresinol-O-alpha-L-rhamnopyranoside using spectroscopic and chemical methods.展开更多
Fe (Si) solid solution being selected as a model material, the single crystal growth of solid solution has been achieved by melting zone of different compositions (MZDC) technique in this study.
