Embodiment Embodiment 1
[0054] The following are non-limiting examples of the present invention Example 1: Preparation of Violet
[0055] 1. Plant material handling
[0056] Take 100 g of fresh leaves of Peristrophe baphia (Spreng.) Bremek. [Peristropheroxbueghiana (schult) Bremek]), add 400 ml of 1% formic acid, mash them, add silicon bath soil filter aid, and obtain the extract. XAD-16 resin column, eluted with 0.1% formic acid to obtain eluent F001. F001 Contains Zilanaminol
[0057] 2. Alkali treatment
[0058] The eluent F001 was basified with dilute ammonia water (0.1%) until blue and purple appeared, and the basified solution F002 was obtained, and violamin was transformed into violacyanin.
[0059] 3. Concentrate
[0060] Concentrate the basified solution F002 under vacuum below 60°C to obtain the concentrated solution F003.
[0061] 4. Column chromatography
[0062] Put the concentrated solution on a C18 bonded phase silica gel column (40-60 μ), elute with water and 30% methanol gradie...
Embodiment 2
[0066] Violet blue pigment: black amorphous solid. C 18 h 17 N 3 o 8 (Molecular weight M=403), ultraviolet-visible spectrum (UV-Vis) figure sees figure 1 , the absorption peak λ max (ε): 239 (24925), 477 (17271) nm in pH3.0 0.05mol / glycine-HCl buffer; at pH7.0 0.1mol / L Na 2 HPO 4 235 (shoulder, 23944), 248 (62150), 279 (11580), 319 (8505), 550 (shoulder, 34347), 382 (38926) nm in the buffer; at pH8.0 0.05mol / L trihydroxy In methylaminomethane buffer, 235 (shoulder peak, 23944), 248 (62150), 279 (11580), 319 (7916), 550 (shoulder peak, 35066), 582 (41347) nm. Infrared Spectrum IR(KBr)ν max 806, 844, 876, 938, 993, 1013, 1090, 1131, 1158, 1177, 1204, 1223, 1259, 1284, 1308, 1335, 1370, 1402, 1458, 1477, 1508, 1521, 1572, 1603, 1641, 1680 (shoulder peak), 2500-3600 (broad peak), the spectrum is shown in figure 2 . The NMR spectra of Violet Blue are shown in Table 2. Pseudomolecular ions were measured by matrix-assisted laser desorption ionization time-of-flight mass...
Embodiment 3
[0078] The fine jelly (T006) was dispersed with 50 ml of pyridine-isopropanol (1:9), filtered, and the filter cake was washed with 50 ml of pyridine-isopropanol (1:9), and then washed with 30 ml of isopropanol, and then Washed with 30ml of acetone and dried to obtain 191mg of pure violacein as a black amorphous solid. Embodiment 3: the influence of heating rate
[0079] Take 50g of fresh mountain indigo, put it in a 500mL conical flask, and inject N 2 , Add 400 mL of boiling deoxygenated distilled water. Divided into rapid heating group and controlled heating group. The rapid temperature rise test uses 89°C hot water to quickly mix with materials (room temperature 22°C) (the sample bottle is preheated in an 82°C water bath about 0.7 minutes before mixing), and the materials can reach an equilibrium temperature of about 82°C once they are mixed. In this way, the time for the material to go from 50°C to 70°C is almost 0, and it is kept in an 82°C water bath for 110 minutes. ...
