Embodiment 1
[0023] 1) Preparation includes:
[0024] Dissolve 10 g of heme derived from commercial or animal blood extracts in acetic acid solution (100 ml) of 33% hydrobromic acid, stir at room temperature for 48 hours, then slowly add methanol, reflux for 2 hours, and concentrate under reduced pressure to remove the solvent. The residue was then suspended in water, the pH was adjusted to 8 with 2N aqueous sodium hydroxide solution, and the solid was collected by filtration. Dissolve the dried solid in methanol solution of 1N sodium hydroxide, reflux for 30 minutes, concentrate the methanol solution to dryness, dissolve the obtained solid in water, adjust the pH to 3~5 with acetic acid solution, collect the solid, and separate Required filter additives (R 1 =R 2 =CH 3 ),
[0025] 1HNMR(d6-DMSO): -3.04(2H,s),2.18(6H,d,J=5.6Hz),2.96(4H,t,J=8.4Hz),3.56~3.72(18H,m),4.33( 4H,t,J=8.4Hz),6.10(2H,d,J=5.6Hz),10.23(1H,s),10.51(1H,s),10.59(1H,s),10.71(1H,s).
[0026] ESI-MS(Positive mode): 62...
Embodiment 2
[0032] Example 2: The difference from Example 1 is that in 2), the filter additive prepared in 2) was suspended in ethanol at 0.1% of the weight of the carrier, and evenly sprayed on the carrier tea foam. The test results are shown in Table 2.
