1978) and chalcones, as 2',6'dihydroxy-4',4'-dihydroxychalcone (Sukuruman and Ramadasan, 1991).
Many of them possess antifungal properties, especially the polymethylated flavones and the prenylated isoflavones as well as various chalcones and flavanones (Williamson and al.
radiata, which is found in tropical America and Japan, has been analysed and shown to contain active constituents including flavonoids, polyacetylenes, flavone glycosides, chalcones, aurones and phenylpropanoids (3).
It is grown in India, Spain, Iran, Russia, China & Italy, The herb contains glycyrrhizin, glycyrrhetinic acid, flavonoids, asparagines, iso-flavonoids, and chalcones.
Antiangiogenic effects of flavonoids and chalcones.
The inhibition of conjugated diene formation may be related to hydroperoxide interacting polyphenol compounds like flavones, coumarins, chalcones and cinnamic acids which may neutralise hydroperoxides by the reduction process (Tiwari 2004).
The new method can manufacture chalcones by tank culture.
4] proposed the concept of "microwave-induced organic reaction enhancement" chemistry (MORE) based on the 100 to 600-fold reaction rate enhancement they observed for the synthesis reactions of chalcones and related enones.
Chalcones, flavanones, and flavones are nod-gene inducers in alfalfa, pea, vetch, and clover; whereas isoflavones, especially daidzein and its conjugates, are the major initial signals in soybean and bean (Graham, [TABULAR DATA FOR TABLE I OMITTED] 1991; Hirsch, 1992; Grady et al.

To the best of our knowledge, the cytotoxicity of dorsmanin F (1) and poinsettifolin B (2) is being reported here for the first time, although the cytotoxicity of flavonoids in general and especially flavanone and chalcones has been largely documented (Dzoyem et al.
