Optimization of Prescription of Lycii Fructus Polysaccharide Buccal Tablets by Central Composite Design-response Surface Methodology and Investigation of Its Immunomodulatory Effect
To prepare Lycii Fructus polysaccharide buccal tablets and investigate its immunomodulatory effect.
Method:
2
Taking the appearance
taste
hardness and disintegration time of the tablets as comprehensive evaluation index
based on single factor tests
central composite design-response surface methodology was adopted to optimize the prescription of Lycii Fructus polysaccharide buccal tablets with mass ratio of dextrin to mannitol
mass ratio of cyclamate to malic acid and dosage of sodium carboxymethyl starch (CMS-Na) as factors. Kunming mice were randomly divided into 5 groups
namely the Lycii Fructus polysaccharide buccal tablets low (100 mg·kg
-1
·d
-1
)
medium (200 mg·kg
-1
·d
-1
) and high (300 mg·kg
-1
·d
-1
) dose groups
the normal group (0.9% normal saline
300 mg·kg
-1
·d
-1
) and the positive medicine group (Cinengsu group
300 mg·kg
-1
·d
-1
). The immunomodulatory effect of the buccal tablets were investigated by calculating immune organ index
monocyte-macrophage phagocytic index
serum hemolysin antibody level
and the voix pedis thickness difference of delayed hypersensitivity (DTH) of mice.
Result:
2
Optimal prescription for the buccal tablets was 80% of Lycii Fructus extract
11.5% of dextrin-mannitol (1.2∶1)
1% of cyclamate-malic acid (1∶1)
0.5% of cream essence
6.5% of CMS-Na
0.5% of magnesium stearate
and appropriate amount of 80% ethanol. Under the optimal condition
the hardness of the buccal tablets was 11.83 kg
its disintegration time was 13.21 min
both of which were in line with the relevant provisions of the 2015 edition of
Chinese Pharmacopoeia
and the buccal tablets had good appearance and taste. Compared with the normal group
medium and high dose groups of Lycii Fructus polysaccharide buccal tablets significantly increased thymus index
spleen index and phagocytic index of mice (
P
<
0.05
P
<
0.01)
serum hemolysin antibody level of mice was significantly increased in all Lycii Fructus polysaccharide buccal tablets groups (
P
<
0.05
P
<
0.01)
and DTH level of mice was significantly increased in high dose group of Lycii Fructus polysaccharide buccal tablets (
P
<
0.05).
Conclusion:
2
The formulation process of the buccal tablets optimized by central composite design-response surface methodology is stable and feasible
and Lycii Fructus polysaccharide buccal tablets can improve the immune regulation function of normal mice
and this study can provide experimental basis for the development
utilization and clinical application of Lycii Fructus and Lycii Fructus polysaccharides.
