(1) screening of enzyme class
Weigh 2.000g short-tube lycoris bulb powder, with solid-liquid ratio 1:10(g:ML) it is separately added into the water that pH is adjusted to 4.5, respectively
The cellulase of addition material quality 3%, hemicellulase, the mixed enzyme of pectase, cellulase and hemicellulase, fiber
The mixed enzyme of mixed enzyme, hemicellulase and pectase of plain enzyme and pectase, cellulase and hemicellulase and pectase
Mixed enzyme, 50 DEG C digest 2.0h, be centrifuged 20min, filter, take supernatant.Result of the test is shown in Table 1, using cellulase with
The yield highest of lycorine during the mixed enzyme of pectase, and cellulase is 1 with the mass ratio of pectase:1.
Lycorine under the different enzyme effect of table 1 extracts result
Enzyme class | Lycorine yield (%) |
Cellulase | 0.1474 |
Hemicellulase | 0.1447 |
Pectase | 0.1480 |
Cellulase and hemicellulase complex enzyme | 0.1530 |
Cellulase and pectase complex enzyme | 0.1575 |
Hemicellulase and pectase complex enzyme | 0.1500 |
Cellulase and hemicellulase and pectase complex enzyme | 0.1521 |
It is not added with enzyme | 0.0902 |
(2) impact of pH
With reference to Fig. 1, weigh 2.000g short-tube lycoris bulb powder, be separately added into pH be 1.5,3.0,4.5,5.0,6.0,7.5
Water 20mL, adds cellulase and the pectase mixed enzyme of short-tube lycoris bulb powder quality 3%, the quality of cellulase and pectase
Than for 1:Digest 2.0h under the conditions of 150 DEG C, be centrifuged 20min, filter, take supernatant.Investigate the impact to lycorine yield for the pH.Figure
1 shows, the yield highest of galanthamine and lycorine when Extractant pH is 4.5, this is because cellulase and pectase
Optimal use pH is 4.5 about, when off-target uses pH, the inactivation of enzyme or part can be caused to inactivate, thus affecting to extract
Yield, therefore selects pH to be tested for 4.5.
(3) impact of enzyme dosage
With reference to Fig. 2, weigh 2.000g short-tube lycoris bulb powder, the water 20mL adding pH to be 4.5, it is separately added into short-tube lycoris bulb powder
The cellulase of last quality 0,1%, 2%, 3%, 4%, 5% and pectase mixed enzyme, digest 2.0h, centrifugation under the conditions of 50 DEG C
20min, filters, takes supernatant.When result enzyme dosage is excessive, concentration of substrate can not reach saturation to enzyme, leads to the effect of enzyme to be subject to
Caused by suppression, therefore after enzyme dosage is more than 3%, lycorine yield has declined on the contrary with the increase of enzyme dosage.
(4) enzymolysis time
With reference to Fig. 3, weigh 2.000g short-tube lycoris bulb powder, by solid-liquid ratio 1:10(g:ML) add the water that pH is 4.5, add

Digest 0.5 under the conditions of DEG C respectively, 1.0,1.5,2.0,2.5h, be centrifuged 20min, filter, take supernatant.Result in extraction time is
In 0.5-1.5h, the yield of lycorine increases in time and raises.Reaction time is too short, and enzymolysis is insufficient, and works as enzyme concentration and reach
During certain value, the prolongation of time of enzymatic reacting can not dramatically increase extraction effect, or even begins to decline.
(5) impact of hydrolysis temperature
With reference to Fig. 4, weigh 2.000g short-tube lycoris bulb powder, add the water 20mL that pH is 4.5, add short-tube lycoris bulb powder matter
The cellulase of amount 3% and pectase mixed enzyme, cellulase is 1 with the mass ratio of pectase:1;Respectively 40,50,60,
70th, digest 2.0h under the conditions of 80 DEG C respectively, be centrifuged 20min, filter, take supernatant.Result lycorine yield is with extraction temperature
Rising and increase, be gradually lowered after 50 DEG C.Too high or too low for temperature all it is unfavorable for the decomposition to cell membrane for the enzyme, thus can not be
Limits play the effect of enzyme.
(6) impact of solid-liquid ratio
With reference to Fig. 5, weigh 2.000g short-tube lycoris bulb powder, press solid-liquid ratio 1 respectively:5、1:10、1:15、1:20、1:25 add
Enter the water that pH is 4.5, add cellulase and pectase mixed enzyme, cellulase and the pectin of short-tube lycoris bulb powder quality 3%
The mass ratio of enzyme is 1:1;Digest 2.0h at 50 DEG C, be centrifuged 20min, filter, take supernatant.Result lycorine yield is with feed liquid
Rise than increasing, when solid-liquid ratio is 1:When 10, lycorine yield highest.
Orthogonal test
With the yield of lycorine as index, orthogonal test, and intuitively analyzed and be shown in Table 2 and table 3 with the results of analysis of variance.
Table 2 Orthogonal Experiment and Design and result
Table 3 variance analysis
Note:F0.10(2,2)=9.00;F0.05(2,2)=19.00;F0.01(2,2)=99.00
Intuitively analyzed by table 2 and understand that lycorine extracts optimised process and is combined as A2B3C3D2, i.e. 50 DEG C of hydrolysis temperature, enzyme
The aqueous solution that solution time 2.0h, enzyme concentration 4%, extractant are 4.5 for pH, impact lycorine yield each factor primary and secondary order be
Hydrolysis temperature > enzyme dosage > enzymolysis time > digests pH.By table 3 variance analysis, the impact to lycorine yield for the hydrolysis temperature shows
Write (P < 0.05).
Repeatedly extracted for raw material with Lycoris aurea bulb powder under this Optimal technique process, detected during to the 3rd time
Do not go out short-tube lycoris alkaloid substance, lycorine yield is 0.1750%.
HPLC method detects lycorine:Chromatographic column is Kromasil 100-5C18Reversed-phase column (250mm × 4.6mm, 5 μm);Stream
