AI Article Synopsis
- * This new compound is made up of 4'-O-methylgallocatechin linked by a specific bond to another 4'-O-methylgallocatechin.
- * The structures of both olasubscorpioside C and the known compound 4'-O-methylgallocatechin were determined using advanced techniques like NMR and mass spectrometry, confirming their identities through comparisons with existing data.
Article Abstract
From the n-butanol soluble fraction of the ethanol extract of the medicinal plant Olax subscorpioidea, a previously unreported rotameric biflavonoid glycoside constituted of 4'-O-methylgallocatechin-(4α → 8)-4'-O-methylgallocatechin as aglycone named olasubscorpioside C (1) along with the known 4'-O-methylgallocatechin (2) were isolated. Their structures were determined on the basis of spectrometric and spectroscopic techniques including HRFABMS, H and C NMR, DEPT 135 , HSQC, HMBC, ROESY, and CD followed by comparison with the reported data.
