• 英文摘要： Ground powder of the leaf and fruit of Piper betle L., a tropical spice plant grown in Southeast Asia,was prepared and extracted by chloroform, ethanol and water with one solvent only or with 3 solvents insequence. The betel powder and various extracts were added to YES broth to determine their effects onthe growth and aflatoxin production by Aspergillus parasiticus. Results showed that betel leaf powder exhibited higher antimycotic activity than fruit. One halfpercent of ground leaf powder completely inhibited the growth and aflatoxin production by A. parasiticus.Among the solvent extracts, chloroform and ethanol extracts of betel leaf prepared from a single solventextraction showed more antimycotic activity. The ethanol extract of betel leaf at the level of 450 g/mlwould eliminate A. parasiticus growth and aflatoxin production. The antimycotic activity of this ethanolextract was most pronounced at pH 4.
