Abstract
To investigate effect of secondary metabolites fromLiquidambar formosanaHance on loquat fruits storage,macroporous resin extracts fromLiquidambar formosanaHance leaves were used. Loquat fruits were dipped in macroporous resin extracts of different mass concentration(10, 30, 50 mg/mL) for 10 minutes, then stored in 6°C for 30 days. Membrane permeability, peroxide(POD) activity, phenylalanine ammonia lyase(PAL) activity, lignin, decay index, hardness, total soluble solid(TSS) and titratable acid(TA) were determined per 5 days to show quality and physiological character of loquat fruits during storage. The results show that macroporous resin extracts fromLiquidambar formosanaHance leaves can significantly reduce decay index, slow down the increase of hardness and membrane permeability, the decrease of TSS and TA content and the accumulation of lignin content, and inhibit the increase of POD and PAL activity.
