Abstract

Sambiloto (Andrographis paniculata Nees) is one of a medicinal plants containing andrographolide as its primary bioactive component, which is able to inhibit breast cancer cell proliferation. Andrographolide is a diterpene lacton that is sparingly soluble in water. The aim of this study is to improve the solubility of andrographolide in A. paniculata herbs ethyl acetate fraction by microencapsulation method prepared using spray drying. The ethyl acetate fraction of A.paniculata herbs was microencapsulated using PVP K30 and HPMC as the coating polymer in different ratios of ethyl acetat fraction and polymer (1:5; 1:7,5 and 1:10). Microspheres containing ethyl acetate fraction of A.paniculata herbs were evaluated their saturation solubility and in vitro dissolution in aquadest, pH 6.8 phosphate and pH 1.2 chloride medium. The result showed that the microencapsulation could increase the saturation solubility and dissolution rate of andrographolide as compared to the ethyl acetate fraction and andrographolide standard. Compared to the solubility of andrographolide from A. paniculata ethyl acetate fraction, the solubility of andrographolide on ethyl acetate fraction microspheres in aquadest, pH 6.8 phosphate and pH 1.2 chloride medium were increased approximately 23.42-39.34, 19.92-34.83 and 24.56-38.25 folds respectively. Moreover, compared to the solubility of andrographolide standard, the solubility of andrographolide on ethyl acetate fraction microspheres in aquadest, pH 6.8 phosphate and pH 1.2 chloride medium were increased approximately 16.99-28.53, 19.76-34.54 and 17.26-26.87 folds respectively.

Abstract

Sambiloto (Andrographis paniculata Nees) is a medicinal plant containing andrographolide as its primary bioactive component, which has been shown to inhibit breast cancer cell proliferation. Andrographolide is a diterpene lacton and sparingly soluble in water. The aim of this study is to prepare microspheres of A . paniculata ethylacetate fraction by microencapsulation using spray drying method. The ethyl acetate fraction of A. paniculata herbs was microencapsulated using PVP K30 and HPMC as the coating polymer in different ratios of 1:5; 1:7,5 and 1:10. Microspheres containing the ethyl acetate fraction of A. paniculata herbs were characterized in term of recovery factor, morphology, particle size distribution, water content and entrapment efficiency. The results showed that the A. paniculata microspheres have the recovery factor of 19,50% to 31,64%, spherical shape varies from smooth surface to irregular shape, particles size of 1,44% to 19,23 µm, moisture content of 5,15% to 13,44%, and entrapment echiency between 94,83 to 112,15%.

Abstract

This study was purposed to prepare microcapsules of ketoprofen by coacervation and spray drying methods and to characterize the resulting microcapsules. The microcapsules were prepared using pregelatinized cassava starch (PCS) and pregelatinized cassava starch phthalate (PCSPh) as a coating material. The obtained microcapsules were then characterized, including its recovery, shape and morphology, drug-loading efficiency, particle size distribution, swelling index, functional Groupanalysis, and drug release profile.The used PCSPh had a substitution degree of 0.0541 and soluble in basic aqueous medium. Microcapsules prepared by coacervation method had an irregular shape and a hollow surface and the entrapment efficiency of 20.27% ± 1.82.Whereas, the spray dried microcapsules showed a nearly-spherical-shape with a biconcave surface and the entrapment efficiency was 80.22% ± 9.18. The release study results showed that within 8 hours ketoprofen released from the coacervation microcapsulesat pH 1.2 and pH 7.4 were 8% and 18%, respectively. In addition, ketoprofen released from spray-dried microcapsules within 8 hours at pH 1.2 and pH 7.4 were 5% and 25%, respectively. In conclusion, the microcapsules prepared by both methods could extent the drug released, thus it could be possible to be used for a sustained release device.
