Method for identifying dendrobium officinale medicinal material based on near infrared spectroscopy

Abstract

The invention discloses a method for identifying a dendrobium officinale medicinal material based on near infrared spectroscopy. The method comprises the following steps: 1) acquisition and preparation of a dendrobium officinale sample; 2) acquisition of a near infrared spectroscopy of the dendrobium officinale sample; 4) selection of a best spectrum data pre-processing method; 4) selection of a best modeling spectrum scope; 5) establishment of a correction model for indentifying dendrobium officinale based on the near infrared spectroscopy data of dendrobium officinale; 6) evaluation of the performance of the correction model; and 7) acquisition and processing of the near infrared spectroscopy of the dendrobium officinale sample to be analyzed by the same method, and identification of the dendrobium officinale by using the correction model. The method has the advantages of reasonable design, strong operationality, fast identification speed, high identification accuracy, and no pollution for detection, and has important application value on quality control of the dendrobium officinale medicinal material and efficacy guarantee of the dendrobium officinale medicinal material.

Description

Technical field [0001] The invention relates to a method for identifying Dendrobium officinale medicinal materials, in particular to a method for quickly and accurately identifying Dendrobium officinale medicinal materials by near-infrared spectroscopy combined with multivariate statistical analysis technology, and belongs to the technical field of traditional Chinese medicine detection and quality control. Background technique [0002] Dendrobium officinale Kimum et Migo (Dendrobium officinale Kimum et Migo) is a perennial epiphytic herb of the Orchidaceae Dendrobium genus (Dendrobium). It is commonly known as officinale and black knotweed. It is a traditional Chinese medicinal material and is located at the top of the "Nine Great Immortals". Dendrobium officinale is sweet in taste, slightly cold in nature; nourishes the stomach; nourishes yin and clears away heat; nourishes the lungs and kidneys; improves eyesight and strengthens waist. [0003] DENDROBII OFFICINALIS CAULIS is th...
