Problems solved by technology

In recent years, studies have shown that Hemerocallis flower has obvious antidepressant effect, and the preparation made from Hemerocallis flower extract can effectively treat depression, but there are still few researches on the quality inspection of Hemerocallis flower preparation, which will affect the quality and curative effect of the product. It is not conducive to the standardized production of medicines and the improvement of production efficiency, and it is not in line with the development trend of modern Chinese medicine

experiment example 1

[0086] Experimental example 1 TLC identification experiment

[0087] 1 Instruments and materials

[0088] 1.1 Instruments TU-1810 UV-Vis Spectrophotometer (Beijing General Instrument Co., Ltd.); SD-20 Shimadzu Liquid Chromatograph (Japan), Quaternary Pump (LC-20ATvp), SPD-M20A Diode Array Detector, LC-liquid chromatography workstation. Sartorius electronic analytical balance (BT 125D). KQ3200DE Ultrasonic Apparatus (Kunshan Ultrasonic Instrument Co., Ltd.).

[0089] 1.2 Material preparation samples were prepared by Beijing University of Traditional Chinese Medicine (same as Example 1); rutin reference substance was purchased from China Institute for Food and Drug Control (100080-200707), methanol was chromatographically pure (Fisher Company); water was Watsons purified water; All other reagents were analytically pure.

experiment example 2

[0094] The total flavone content determination experiment of experimental example 2 ultraviolet spectrophotometry

[0095] 1 Selection of measurement wavelength

[0096] After the rutin standard solution and Hemerocallis extract were color developed according to the experimental method, they were scanned in the wavelength range of 400-600nm. As a result, the rutin standard solution had the maximum absorption at 510nm after the color development, and the Hemerocallis extract also had color development at this wavelength. Absorption, the experiment chooses 510nm as the measuring wavelength.

[0097] 2 Preparation of the test solution

[0098] Accurately weigh 20mg of the preparation (prepared by Example 1), put it in a 10mL measuring bottle, add 30% ethanol to the mark, and process it ultrasonically for 10min to obtain it.

[0131] The rutin content determination experiment of experimental example 3HPLC method

[0132] 1 Chromatographic conditions and system suitability test

[0133] Octadecylsilane bonded silica gel is used as filler; methanol: 0.5% glacial acetic acid solution (40:60) is used as mobile phase; the number of theoretical plates should not be less than 3000 based on the rutin peak.

[0134] 2 Selection of measurement wavelength

[0135] Get the rutin reference substance and the sample solution into the liquid phase respectively, DAD detector detection, the spectrogram of rutin shows that there are two large absorption peaks at 254nm and 365nm, but the number of peaks detected by the sample at 254nm is more, so 254nm was selected as the measurement wavelength.

[0136] 3 Preparation of reference solution

[0137] Accurately weigh an appropriate amount of rutin reference substance, add methanol to make a solution containing 0.4mg per 1mL, shake well, and obtain.

Description

technical field [0001] The invention relates to a detection method of traditional Chinese medicine and its preparation, in particular to a detection method of Hemerocallis flower and its preparation. Background technique [0002] Hemerocallis citrina Baroni (Hemerocallis citrina Baroni), also known as "day lily" and "one day lily", commonly known as "forgetfulness grass", belongs to the perennial herbaceous plant of the genus Hemerocallis genus in the family Liliaceae. Rich in nutrients, the main chemical components are protein, fat, carbohydrates, and a variety of vitamins, alkaloids, glycosides, flavonoids, carotene, volatile oils, tannins, and inorganic minerals calcium and phosphorus, mainly flavonoids The ingredients can be used for both medicine and food. Li Shizhen of the Ming Dynasty said in "Compendium of Materia Medica" that it has the effects of calming the nerves and refreshing the brain, increasing wisdom and widening the chest, beautifying and nourishing blood,...
