RESULTS Eleven compouds were isolated and identified as shizukanolide(Ⅰ) , furanodienone (Ⅱ) , lupeol (Ⅲ) , 24-hydroxylupeol (Ⅳ) , pinostrobin (Ⅴ) , 2 , 6 -dihydroxy-4 -methoxydihydrochalcone (Ⅵ), 7-rnethylnaringenin(Ⅶ) , eleutheroside B1 (Ⅷ), 3,4-dihydroxybenzonic acid(Ⅸ), palmitic acid(Ⅹ) and β-sitosterol(Ⅺ), respectively.

Microsomes were prepared from etiolated wheat seedlings pretreated with 5%(v/v) ethanol and 10mmol/L Pyribambenz-propyl for 24h at 25℃ in a dark and reacted with [C ring-U-()~(14)C] pyribambenz-propyl).

In the present study, oxidative stress was studied in seedlings of two rice cultivars with different chilling tolerance after treatments of paraquat,pyribambenz-propyl and chilling.

One of these compounds, pyribambenz-propyl was successfully developed as a potent herbicide for rape field.
