[0043] 1. Preparation and collection of processed products: Raw Puhuang was purchased from Tongzhou, Nantong, with batch number 20180820, and was identified as pollen of Typha orientalis Presl by the School of Pharmacy, Nanjing University of Traditional Chinese Medicine. Under the guidance of senior processing experts and on the basis of previous processing technology research, 45 batches of fried charcoal samples, 82 batches of puhuang charcoal, 66 batches of puhuang charcoal samples, and a total of 193 batches of puhuang charcoal processed products were prepared.
[0044] 2. The Fourier transform near-infrared spectrum of the collected samples: take 5g of 193 batches of puhuang processed products (passed through the No. 7 sieve), and put them in the quartz sample cup, the number of scans is 32 times, and the resolution is 8cm -1 , spectral range 12000~4000cm -1 , tested at 22-27°C, 60% humidity environment, each sample was measured three times, and the average spectrum was t...
