A new special flavone, named desmosdumotin B, was isolated from the roots of D. dumosus and its chemical structure identified as 5-hydroxy-7-one-6,8,8-trimethylflavone by spectral analysis and X-ray.
A new flavone, named desmosflavene,,as isolated from the roots of Desmos cochinchinens is Lour., and its chemical structure,as established on the bas is of spectral analysis and chemical reaction.
Three compounds were isolated from the roots of Cocculus trilobus DC. Their Ghemical structures were elucidated as β-sitosterol (V). 1.2-dehydroapateline (Ⅵ) and neotrilobine (Ⅶ) by spectral analysis.
