不同采摘时间和地域龙陵紫皮石斛水浸出物和粗纤维含量变化分析
目的 全面了解龙陵县龙山镇、龙新乡、象达乡等6个乡镇9月份与12月份采摘的紫皮石斛水浸出物、粗纤维含量及其变化规律。方法 分别采集9月份、12月份龙陵县6个乡镇的紫皮石斛, 利用沸水浴提取、干燥、称重法测定水浸出物含量, 酸碱消煮、干燥、灰化法测定粗纤维含量。结果 9月份龙陵紫皮石斛水浸出物含量在36.50%~46.00%之间, 粗纤维含量在12.35%~16.01%之间, 12月份水浸出物含量在44.60%~52.35%之间, 粗纤维含量在14.99%~17.10%之间, 不同地域水浸出物含量差值在1.8%~10.7%之间, 粗纤维含量差值在1.09%~2.64%之间。结论 12月份龙陵紫皮石斛水浸出物和粗纤维含量高于9月份, 内含物丰富、含量稳定。本研究为确定适宜的采收时期和石斛资源的综合利用提供科学依据。
Objective To find out the variation of content of water extract and crude fibre from Dendrobium devonianum Paxt. in September and December of 6 townships. Methods Dendrobium devonianum Paxt. from 6 townships in Longling were collected in September and December, and extracted by means of boiling water bath. Water extract content was determined by drying and weighing, and crude fiber content was determined by acid and alkali boiling, drying, and ashing. Results Water extract content were 36.50%~46.00% in September and 44.60%~52.35% in December, and crude fibre content were 12.35%~16.01% in September and 14.99%~17.10% in December. The difference of water extract content of different regions was 1.80%~10.7%, and crude fibre content of different regions was 1.09%~2.64%. Conclusion The contents of water extract and crude fibre of Dendrobium devonianum Paxt. are higher in December than those in September. It can provide scientific basis for determination of suitable harvesting time and comprehensive utilization of dendrobium resources.
