Embodiment 1

[0039] (1) NIR spectroscopy data collection of honeysuckle medicinal materials

[0040] Honeysuckle medicinal materials from different origins were crushed and passed through an 80-mesh sieve to obtain honeysuckle medicinal powder with a relatively uniform particle size. The obtained honeysuckle medicinal powder was accurately weighed and placed in a flat bottle to keep the powder surface flat and collected by diffuse reflection method. IR. Spectral acquisition conditions: air is used as a reference, the scanning range is 4000-12000 cm -1 , The number of scans is 32, the resolution is 8 cm -1 . The scan of each batch of samples is repeated 3 times, and the average spectrum is taken. See the attachment for the near-infrared raw absorption spectra of honeysuckle powder figure 1 .

Abstract

The invention provides a multi-index quick detection method of honeysuckle. The method comprises the following steps: gathering the honeysuckle; measuring the content of moisture, extract, chlorogenic acid and galuteolin in the honeysuckle; collecting near-infrared spectrum data and preprocessing; building quality control index models and quickly detecting the models. According to the method, an near-infrared spectrum technology is introduced as a detection method for real-time release of the honeysuckle; the method can be used for quickly measuring the content of moisture, extract, chlorogenic acid and galuteolin in the honeysuckle; compared with a conventional method, the built analytic method and quantitative criterion for real-time release can quickly judge whether the quality of the honeysuckle is qualified or not and confirm whether the honeysuckle can enter subsequent production process links or not, and the method meets quick and efficient field requirements in the actual production and has application prospects of production herb screening and comprehensive quality evaluation.

Description

Technical field [0001] The invention belongs to the field of near-infrared analysis and detection, and specifically relates to a multi-index fast detection method for honeysuckle medicinal materials. Background technique [0002] Honeysuckle is honeysuckle ( Lonicera japonica Thunb.)’s dried flower buds or blooming flowers are one of the top ten rare medicinal materials in the country. It has high health and medicinal value and is highly valued by scholars and entrepreneurs at home and abroad. Honeysuckle has a sweet and cold nature and is returned to the lung, heart, and stomach meridians. It has the functions of clearing heat and detoxifying, cooling and dispelling wind-heat. It is used for carbuncle, swelling, furunculosis, throat numbness, erysipelas, febrile dysentery, wind-heat cold, fever and other disease. Honeysuckle contains a variety of pharmacologically active ingredients. Among them, chlorogenic acid and flavonoids are the main medicinal ingredients in honeysuckle, ...
