Abstract

The pharmacokinetic and metabolic profiles of polar extract compounds from Curcuma rhizoma were evaluated using ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) predictions. Most compounds exhibited high gastrointestinal (GI) absorption, with the exception of D-glucose, citric acid, and terpenoids such as alpha-pinene and zingiberene, which demonstrated low absorption, highlighting potential challenges for systemic bioavailability. Blood-brain barrier (BBB) permeability was observed in lipophilic compounds like xanthorrhizol, bisdemethoxycurcumin, and terpenoids, suggesting their potential for CNS-targeted therapies, while polar compounds, including D-glucose, citric acid, and most curcuminoids, were non-permeant. D-glucose was the only compound identified as a P-glycoprotein (Pgp) substrate, indicating minimal efflux-related limitations for other compounds. Selective cytochrome P450 (CYP) enzyme inhibition was detected in compounds such as xanthorrhizol, curcuminoids, and zingiberene, suggesting potential metabolic interactions in multi-drug contexts. Promising therapeutic candidates include curcuminoids and xanthorrhizol, while non-BBB-permeant and low-absorbing compounds may require formulation strategies or alternative applications. These findings provide valuable insights into the pharmacological optimization of Curcuma rhizoma compounds, offering a foundation for further research in drug discovery and development.

Abstract

Background: Phenolic and flavonoid compounds from soursop (Annona muricata) leaves and red dragon fruit (Hylocereus polyrhizus) peel have potential applications in lotion formulations; therefore, their quantification is important for quality evaluation. Objective: To determine total phenolic content (TPC) and total flavonoid content (TFC) in lotion formulations containing combined plant extracts and to assess the analytical method performance. Method; Four formulations were prepared: F0 (without extract), F1 (0.5% + 0.5%), F2 (1.0% + 1.0%), and F3 (1.5% + 1.5%). TPC was measured using the Folin–Ciocalteu method (mg GAE/g) and TFC using the AlCl₃ colorimetric method (mg QE/g). Method validation included repeatability (%RSD, n = 6) and spike-recovery accuracy at 80–120%. Results: The method showed good precision (%RSD 1.08% for TPC and 1.21% for TFC) and acceptable accuracy with recoveries of 98–102%. F0 showed non-detectable values, while increasing extract concentration resulted in higher TPC (3.82 ± 0.14 to 9.71 ± 0.33 mg GAE/g) and TFC (0.86 ± 0.05 to 2.35 ± 0.10 mg QE/g). Differences among formulations were statistically significant (p < 0.05). Conclusion: The UV–Vis method is suitable for determining TPC and TFC in lotion matrices, and higher levels of combined extracts significantly increase both parameters, supporting their use for quality standardization of herbal lotions.
