包装
Bottomless glass bottle. Contents are inside inserted fused cone.
其他说明
This compound is commonly found in plants of the genus: humulus
For this product we use the non-stereospecific CAS number. It is expected that the natural enantiomer is predominant, however the substance is prone to racemization in solution. The product is therefore not specified stereospecifically and is only recommended to be used for non-stereospecific analysis.

Sophoraflavanone B (SPF-B), a known prenylated flavonoid, was isolated from the roots of Desmodium caudatum. The aim of this study was to determine the antimicrobial synergism of SPF-B combined with antibiotics against methicillin-resistant Staphylococcus aureus (MRSA). MRSA, a multidrug-resistant pathogen
