Abstract: Using chloroform as solvent,Under the extraction conditions of extraction time 10 h,size of betel nut power 20 to 40 mesh,the betel nut oil extraction rates of two varieties of Hainan and Thailand were compared by different drying methods. Results showed that the betel nut oil extraction rate of Thaiand variety is higher than that of Hainan variety,and the oil extraction rate of one variety of betel nut dried by hot air is higher than that of the same variety of betel nut dried by microwave.

Key words: betel nut oil, drying, extraction rate
