Suaveolic Acid: A Potent Phytotoxic Substance of Hyptis suaveolens
Hyptis suaveolens (Lamiaceae) is an exotic invasive plant in many countries. Earlier studies reported that the aqueous, methanol, and aqueous methanol extract of H. suaveolens and its residues have phytotoxic properties. However, to date, the phytotoxic substances of this plant have not been reported. Therefore, the objectives of this study were isolation and identification of phytotoxic substa...
متن کاملOnion, a Potent Inhibitor of Xantine Oxidase
Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...

متن کاملRecombinant p-hydroxyphenylpyruvate dioxygenase of high activity.
Inhibitors of p-hydroxyphenylpyruvate dioxygenase (HPPD) are bleaching compounds impairing the formation of colored carotenoids. This activity makes them promising candidates for herbicides. Detailed studies on enzyme-inhibitor complexes or on the binding niche of the enzyme have still to be performed. Enzyme preparation from plants is time-consuming and the yield is poor. This paper describes ...
متن کاملThe Interaction of Hydroxymandelate Synthase with the 4-Hydroxyphenylpyruvate Dioxygenase Inhibitor: NTBC.
Hydroxymandelate synthase (HMS) catalyzes the committed step in the formation of para-hydroxyphenylglycine, a recurrent substructure of polycyclic non-ribosomal peptide antibiotics such as vancomycin. HMS uses the same substrates as 4-hydroxyphenylpyruvate dioxygenase (HPPD), 4-hydroxyphenylpyruvate (HPP) and O(2), and also conducts a dioxygenation reaction. The difference between the two lies ...
