Synthesis of flavanone-6-carboxylic acid derivatives had been conducted via the route of chalcone. The synthesis was carried out from salicylic acid derivative, i.e. 4-hydroxybenzoic acid, via esterification, Fries rearrangement, Claisen-Schmidt condensat... see more

Synthesis of flavanoid compounds of chalcone and flavanone groups have been conducted. Flavanoid Is one of the group natural products which is mostly found in plants and have been proved to have physiological activity as drug. In this research, chalcone p... see more

Dimethylcardamonin (DMC) or (E)-2’,4’-dihydroxy-6’-methoxy-3’,5’-dimethyl chalcone was isolated from Syzygium samarangense (Blume) Merr. leaves using vacuum liquid chromatography and normal phase silica-gel column chromatography. DMC was purified from the... see more

For the first time the structural determination of the biflavonoid, 4-H-2,3-dihydro-1-benzopyran-4-one-6-[2-phenyl-8-(3-methyl-2-butenyl)-5,7-dimethoxy-2-H-3,4-dihydro-1-benzopiran-4-yl)-5,7-dihydroxy-8-(3-methyl-2-butenyl)-2-phenyl, named toxicarine (1) ... see more

The Flavanone compound with anti diabetic activity was isolated from ethyl acetate extract of Artocarpus communis leaves using column chromatography techniques. The structure of the flavanone compound was elucidated on the basic of spectroscopic evidence ... see more

Phytochemical investigations on the chloroform extract of the arial part of Orthosiphon stamineus resulted in isolation of one new prenylated compound 5,7-dimethoxy-3,4'-dihydroxy-3',8-di-C-prenylflavanone together with four known flavonoids compounds, si... see more

Two flavanone derivatives, norartocarpanone (1) and euchrenone a7 (2) had been isolated for the first time from the methanol extract of the wood of Morus nigra. The structures of these compounds were determined base on spectral evidence, including UV, IR,... see more

Phytochemical study on the resin of Dracaenaceae obtained from Socotra Island has been conducted. The separations of the chemical components were carried out by different chromatography techniques and their structures were elucidated by spectroscopic meth... see more

Flavonoids are a part of the large group of polyphenols, and they are found in tea, fruit, vegetables, and red wine. The daily flavonoid (flavonols and flavanones) intake in Denmark was calculated based on consumption and analysis of flavonoid contents of... see more
