Abstract

Clitoria ternatea or known as the butterfly pea is widely used in the health sector due to its efficacy as antidiabetic, anti-inflammatory, antimicrobial, anticancer, analgesic, antipyretic, and antioxidants. The purpose of this research is to examine the antioxidants and tyrosinase inhibitor activities of butterfly pea ethanol extract as well as to identify the phytochemical content. Antioxidants activities are determined by the DPPH method. The results of this study indicates that butterfly pea extract has very weak antioxidant activities with an IC50 value more than 200 ppm. The results of the tyrosinase inhibitor activities showed that the butterfly pea extract did not inhibit the tyrosinase enzyme. Based on the screening phytochemical tests, the chemical components contained in butterfly pea extract are flavonoids, tannins, saponins, and steroids. Bunga telang flower extract has very weak antioxidant activity and tyrosinase inhibitor testing showed antioxidant flower extract by DPPH method. Tyrosinase inhibitor assay results showed white Bungatelang extract has no activity to inhibit tyrosinase enzyme.

Abstract

Apple cider vinegar and rosemary oil have an acaricidal effect on R. sanguineus ticks. Both ingredients offer health benefits. This study aimed to observe the effect of a spray preparation containing apple cider vinegar and rosemary oil at various concentrations on the mortality of R. sanguineus ticks. The study was conducted from February 2025 to April 2025. It used 75 R. sanguineus ticks, divided into 5 groups, with each group having three repetitions. K1, the negative control, was treated with pure distilled water. K2, the positive control, was treated with Fipronil 3% (Frontline brand). K3 was given bergamot oil 5%, rosemary oil 10%, and apple cider vinegar 5%. K4 was given bergamot oil 5%, rosemary oil 10%, and apple cider vinegar 10%. K5 was given bergamot oil 5%, rosemary oil 10%, and apple cider vinegar 15%. Each treatment group consisted of 5 ticks. Observations were made at 30, 60, 90, 120, and 180 minutes post-contact. The results showed that the group treated with bergamot oil 5%, rosemary oil 10%, and apple cider vinegar 15% achieved a Lethal Time 50 (LT50) at 106 minutes. The conclusion indicates that apple cider vinegar at a concentration of 15% required the least amount of time to kill the ticks

Abstract

Hyperpigmentation was driven by increased melanogenesis and oxidative stress, creating a need for effective and safe depigmenting candidates. This study aimed to identify bioactive compounds from Hylocereus costaricensis, to map hyperpigmentation-related targets and pathways using network pharmacology, and to evaluate the binding potential of selected compounds to a melanogenesis target using molecular docking. The workflow included compound screening and drug-likeness/ADMET evaluation, prediction of compound targets and hyperpigmentation-associated genes, construction of compound–target–disease and protein–protein interaction networks, topological and GO/KEGG enrichment analyses, and docking to TYRP1 (PDB: 5M8O). Five main candidates, namely 2,2-dimethyl-3-phenylpropanoic acid, ferulic acid, o-coumaric acid, p-coumaric acid, and vanillic acid, have met the initial criteria. Network pharmacology highlighted a multi-target mechanism by prioritizing key nodes including AKT1, EGFR, PIK3CA, TYR, and CDK4 and by indicating enriched signaling pathways relevant to pigmentation regulation and oxidative-stress responses. Docking results showed moderate affinities, with binding energies of approximately −6.551 to −6.184 kcal/mol and estimated inhibition constants of 15.779 to 29.315 µM, and 2,2-dimethyl-3-phenylpropanoic acid yielded the best score among the tested ligands. Overall, the integrated network pharmacology–docking strategy provided a rational prioritization of compounds and targets for developing anti-hyperpigmentation agents derived from H. costaricensis; however, the evidence remained preliminary and required further experimental validation and mechanistic confirmation.
