Embodiment 1
[0049] The establishment of embodiment 1 sunflower disc HPLC standard fingerprint
[0050] (1) Preparation of the test solution: take by weighing 0.55g of the sunflower disc extract, accurately weigh, put in a 50ml measuring bottle, add 40ml of methanol, ultrasonicate (power 300W, frequency 25kHz) for 45 minutes, let cool, add methanol to the mark, shake well, filter, and take the filtrate to get it (keep away from light).
[0051] (2) HPLC measurement: adopt following HPLC method to detect 10 described need testing solutions, obtain fingerprint collection (such as figure 2 shown);
[0054] (3) The establishment of standard fingerprints: adopt Chinese ...
Embodiment 2
[0058] The quality evaluation method of embodiment 2 sunflower dish
[0059] (1) Preparation of the sample solution to be tested: take 3 batches of sunflower discs to be tested, prepare the sunflower disc extracts to be tested according to the aforementioned method, take 1g of the sunflower disc extracts respectively, put them into a stoppered conical flask, add 25 mL of methanol, Weigh the weight, sonicate (power 250W, frequency 25kHz) for 45 minutes, let cool, weigh again, add methanol to make up the lost weight, shake well, filter, and get the filtrate to obtain the sample solution to be tested (avoid light save);
[0060] (2) Obtaining of the fingerprint of the sample to be tested: adopt the same HPLC method as in Example 1 step (2) to detect the 3 samples of step (1) to obtain the fingerprint;
[0061] (3) Quality judgment: The standard fingerprints obtained in Example 1 and the fingerprints of the sample to be tested were analyzed by using the Chinese medicine chromatog...

Abstract
The invention relates to a method for establishing a sunflower plate HPLC standard fingerprint. The method includes the steps of detecting multiple batches of sunflower plate extraction solutions through an HPLC method to obtain a fingerprint, and analyzing the fingerprint through software to obtain the sunflower plate standard fingerprint. In the standard fingerprint establishing process, great attention is paid to the sequence and relation of all characteristic peaks forming the fingerprint, and attention is paid to the overall appearance characteristics; by optimizing the sunflower plate extract preparation method and the HPLC liquid phase conditions, the obtained standard fingerprint can effectively and accurately express the quality of a sunflower plate, the quality of the sunflower plate can be easily and comprehensively monitored, and the aim of rapidly and accurately identifying the authenticity and quality of the product is achieved.
Description
technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a method for establishing HPLC standard fingerprints of sunflower discs. Background technique [0002] Now the output of Chinese herbal medicines is getting less and less, and it is urgent to develop new materials. Sunflower disc is the sunflower disc after sunflower has taken off its seeds. It is a by-product of sunflower, and its output accounts for about 20% of the sunflower seed output. It is a huge resource in the main sunflower producing areas. [0003] Sunflower disc cures headache, dizziness, toothache, stomach and abdominal pain, women's menstrual pain, sores and swellings. The pharmacological action shows that the ethanol extract of Sunflower Disc can significantly lower blood pressure when administered intravenously to anesthetized cats. Clinical medicine shows that taking an appropriate amount of sunflower dish, adding water to decoct it int...
