ABSTRACT
Objective:
To prepare the hydrogels using Bletilla striata polysaccharides (BSP) as groundmass and evaluate its properties.Methods:
BSP were successfully extracted and characterized by Fourier Transform Infrared Spectrometer, thermogravimetric analysis, differential thermal analysis, and X-ray diffraction. The BSP was incorporated with Carbopol 940 to prepare hydrogels. Rheological behavior of the gels was investigated by rotational rheometer, skin permeation properties and bioactivities of BSP gels were evaluated by trans-epidermal water loss (TEWL) and blood coagulation examinations respectively using mice as model animals.Results:
The BSP was pure with complete structure. The BSP gels showed the better viscoelasticity and physical strength from carbopol gel. The gels showed better skin permeation enhancement and hemostatic activity.Conclusion:
This work demonstrates the skin permeation enhancement and plasma coagulation effects of BSP hydrogels, which show great potential in transdermal drug delivery system and wound dressing.
