ABSTRACT
Objective To extract and determine the total flavonoids in Fordia cauliflora. Methods Total flavonoids in Fordia cauliflora were extracted by microwave technology and determined by colorimetry. Results Total flavonoids in Fordia cauliflora was 1.12%, and recovery rate was 99.5%, RSD was 2.36%. Conclusion The method is convenient, accurate and can be used for the extraction of total flavonoids in Fofdia caulifora.
ABSTRACT
Object To study the chemical constituents of the dried root of Fordia cauliflora Hemsl which is indigenous to Guangxi and commonly used in traditional medicine of Zhuang and Yao nationalities Methods The constituents were isolated with column chromatography and their structures were elucidated on the basis of physicochemical data and spectral analysis Results The three constituents were isolated and identified as 2 [3 methoxyphenyl] 4H furo[2,3 h] 1 benzoyran 4 one (Ⅲ), 3 methoxy 2 [3 hydroxyphenyl] 4H furo [2, 3 h] 1 benzopyran 4 one (Ⅳ) and pinnatin (Ⅴ) Conclusion The all of them are isolated from this plant for the first time Compound Ⅲ,Ⅳ are new and tentatively named as cauliflorin A and cauliflorin B
