Embodiment 1
[0037] A method for rapidly predicting Henan Dendrobium adulterated Huoshanense Dendrobium, comprising the following steps:
[0038] (1) Sample preparation of adulterated Dendrobium huoshanense
[0039] Preparation of samples of adulterated Dendrobium Huoshanense: Pick the collected fresh stems of Dendrobium Huoshanense and Dendrobium Henan, wash them with pure water to remove surface impurities, then cut the stems of Dendrobium Huoshanense and Dendrobium Henan into small pieces, and freeze-dry them at low temperature Freeze-drying in the machine, crushing with a pulverizer, and passing through a 60-mesh sieve to obtain a 60-mesh Dendrobium stem powder and a Dendrobium stem powder from Henan. 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85% , 90%, 95%, and 100% were mixed to obtain 21 groups of adulterated samples, each group of adulterated samples was set with 10 parallel samples, a total of 210 adulterated samples, and the quality of each a...
Embodiment 2
[0051] Preparation of samples of adulterated Dendrobium Huoshanense: Pick the collected fresh stems of Dendrobium Huoshanense and Dendrobium Henan, wash them with pure water to remove surface impurities, then cut the stems of Dendrobium Huoshanense and Dendrobium Henan into small pieces, and freeze-dry them at low temperature Freeze-drying in the machine, crushing with a pulverizer and passing through an 80-mesh sieve to obtain the stem powder of Dendrobium huoshanense and the stem powder of Dendrobium henanensis with a particle size of 80 mesh, the stem powder of dendrobium henanesus and the stem powder of dendrobium huoshanense are respectively 0% according to the mass ratio, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85% , 90%, 95%, and 100% were mixed to obtain 21 groups of adulterated samples, each group of adulterated samples was set with 10 parallel samples, a total of 210 adulterated samples, and the quality of each adulterated sample...
Embodiment 3
[0063] A method for rapidly predicting Henan Dendrobium adulterated Huoshanense Dendrobium, comprising the following steps:
[0064] (1) Sample preparation of adulterated Dendrobium huoshanense
[0065] Pick the collected fresh stems of Dendrobium Huoshanense and Dendrobium Henan, wash them with pure water to remove surface impurities, then cut the stems of Dendrobium Huoshanense and Dendrobium Henan into small sections, freeze-dry them in a low-temperature freeze dryer, and use crushed After the machine is pulverized, it passes through a 100-mesh sieve to obtain a particle size of 100 mesh Dendrobium Huoshanense stem powder and Henan Dendrobium stem powder. The Henan Dendrobium stem powder and Huoshanense Dendrobium stem powder are respectively 0%, 5%, 10%, 15% according to the mass ratio. %, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100% ratio mixed to obtain 21 groups of adulterated samples, 10 parallel samples were set for each group ...
