Abstract

‘Josapine’ is a famous pineapple cultivar as a kind of table fruit with a strong special aromatic fragrance like rose or jasmine, In this paper, ripen fruits were harvested monthly from January to June, and volatile compounds were measured by HS-SPME-GC-MS method to reveal the mysterious aroma compounds. Results showed that 112 volatile compounds totally were found in 5 harvest time. Esters and terpenes are the dominant volatiles among Josapine. February fruits contained the most abundant esters with 80.85% of total volatiles and May fruits contained the richest terpenes with 57.17%. In April and May harvested period, (Z)- β-ocimene was extremely significantly higher than that of other three periods. In March fruit. fruits smelt much more floral than in February and March probably attribute to the abundant (Z)-β-ocimene.
