| description | In order to comprehensive evaluate the quality of Ficus hirta Vahl., which were dried under sun, fumigated by sulfur dioxide, dried by vacuum freezing, and dried by hot air at 50 ℃, the contents of psoralen, total polyphenols, total flavones, soluble sugars and volatile components were determined by HPLC and GC-MS. The results showed that 22, 19, 15 and 12 h was needed to reduce the moisture content of Ficus hirta Vahl. to 15% (safe storage moisture content), respectively. When Ficus hirta Vahl. were dried by sun drying, sulfur dioxide fumigated drying, vacuum freezing drying and 50 ℃ hot air drying, the contents of psoralen were 0.49, 0.60, 0.35 and 0.71 mg/g, respectively. The content of total polyphenols were 1.50, 3.95, 1.44 and 1.59 mg/g, respectively. The content of total flavonoids were 3.91, 4.65, 1.19, 1.55 mg/g, respectively. The content of soluble sugars were 94.95, 83.83, 86.76, 82.19 mg/g, respectively. GC-MS results showed that the relative contents of volatile components were 75.20% , 70.99% , 57.18% and 69.36% respectively in the samples dried by sun-drying, fumigation-sulfur drying, vacuum freeze-drying and 50 ℃ hot-air drying. In actual production, if the weather was fine, sun drying would be the most economical and environmentally friendly drying method. In case of overcast and rainy weather, 50 ℃ hot air drying would be used. |
