Embodiment 1
[0022] Embodiment 1 compound rhinitis spray
[0023] Concrete technological process schematic diagram refers to shown in 1, and preparation method is:
[0024] (1) Take by weighing 3000g Andrographis paniculata L. and cut into small sections less than 5cm, add 85% ethanol to reflux and extract twice, add 9 times of ethanol for the first time, add 8 times of ethanol for the second time, reflux for 1.5 hours each time, combine Medicinal solution, filtered, ethanol recovered from the filtrate, concentrated under reduced pressure to 2 times the amount of the crude drug, added activated carbon with 4% of the crude drug amount and refluxed for 30 minutes, filtered, the filter residue was washed with an appropriate amount of 50-65% ethanol, filtered, and the above filtrates were combined, Recover ethanol, concentrate under reduced pressure into a thick paste with a relative density of 1.15-1.25 (60°C), and set aside;
[0025] (2) Weigh 1000g goose not eating grass, add water and dec...

[0027] Experimental Example 1 Extraction verification test of Andrographis paniculata
[0028] Experimental method: 100g of Andrographis paniculata, cut into sections, add 85% ethanol to reflux twice, add 9 times for the first time, add 8 times for the second time, reflux for 1.5 hours each time, combine the medicinal liquid, filter, weigh, and measure Andrographis paniculata Lactone and dehydroandrographolide content, calculate the total transfer rate, the results are shown in Table 1.
[0029] Table 1 The results of the verification test for the extraction of effective components from Andrographis paniculata
[0030]
[0031] The verification test results are basically consistent, the three tests RSD = 1.75%, indicating that the extraction method has good stability.
experiment example 2
[0032] Experimental example 2 Purification process verification experiment of the extract of Andrographis paniculata
[0033]Experimental method: Three batches of verification were carried out according to the process conditions. Each batch took 1 kg of Andrographis paniculata, cut into small pieces <5 cm, and added 85% ethanol to reflux for extraction twice, adding 9 times for the first time and 8 times for the second time, and refluxed each time Extract for 1.5 hours, combine the decoction, filter, recover the ethanol from the filtrate to 2 times the crude drug amount, add activated carbon with 4% crude drug amount and reflux for 30 minutes, filter while hot, wash the filter residue with an appropriate amount of dilute ethanol, filter, combine the filtrate, and recover Ethanol, measure the total amount of andrographolide and dehydroandrographolide in the liquid medicine, and calculate the transfer rate. The results are shown in Table 2:
