Incorporation of standardised extract of Curcuma longa Linn into phytosomes and its evaluation for in vitro Anti-inflammatory potential and Brine shrimp lethality assay

Abstract

Aim: To incorporate standardized Curcuma longa Linn extract into phytosomes and evaluate for in vitro anti-inflammatory and BSL bioassay. Method: The quality of the plant material was determined by various pharmacognostic parameters. The plant material was then subjected to maceration for extraction using ethanol: water as solvent followed by Soxhlet extraction. The resulting extract was subjected to phytochemical analysis to determine the presence of plant metabolites. The drug and excipients compatibility was evaluated by FTIR study. Furthermore, using the thin film hydration approach, a new lipid-based phytosome was prepared. In vitro anti-inflammatory and brine shrimp lethality tests were performed on prepared phytosome. Results: Moisture content, total ash, acid insoluble ash, water soluble ash values, aqueous, alcohol, and petroleum ether extractive values are all found to be within limits. The phytochemical analysis validated the existence of alkaloids, tannins, resins, carbohydrates, proteins, flavonoids, and saponins. The compatibility study demonstrates the compatibility of excipients with drugs. Thin film hydration technique was employed successfully to prepare the phytosomes containing Curcuma longa linn extract. In vitro anti-inflammatory activity revealed that prepared phytosome could serve as natural based therapeutic option for anti-inflammatory potential. Brine shrimp lethality assay also confirmed the bioactivity of prepared phytosomes. Conclusion: The method used for standardization can be used to aid with plant identification and quality analysis of Curcuma longa Linn for future research. It can be inferred from the findings that phytosomes loaded with Curcuma longa Linn extract exhibited promising anti-inflammatory and cytotoxic effects.
