Abstract

Parijoto (Medinilla speciosa) has a wide range of pharmacological activities due to its secondary metabolite content, especially flavonoid, and phenolic compounds. Flavonoid and phenolic compounds have a major role in human health with their activities as antioxidants, anti-inflammatories, antimicrobials, etc. This study aimed to determine the total levels of phenolic and flavonoid compounds from the ethanol extract of Parijoto fruit. Parijoto fruit is obtained from Bandungan, Semarang Regency, Central Java. Extraction was carried out by maceration method with 70% ethanol solvent then concentrated using a rotary evaporator. The total phenolic and flavonoid content amount was determined using the colorimetric method with Folin-ciocalteau complex reagent on phenolic with gallic acid as the reference standard and AlCl3 complex reagent on flavonoids with quercetin as the reference standard. Absorbance was measured using a UV-Vis spectrophotometer. The results showed that the color of the viscous extract of Parijoto fruit was dark brown with a yield of 6.67% w/w. The total phenolic content of the ethanol extract of Parijoto fruit was 21.67 µgGAE/g extract and the total flavonoid content was 9.21 µg QE/g extract.

Abstract

Carica seeds (Carica pubescens) contain alkaloid, saponin, and flavonoid compounds, which have pharmacological activities such as antibacterial, anti-inflammatory, immunomodulatory, and antihyperlipidemic properties, but their bioavailability is low. Nanotechnology has significantly advanced in drug delivery systems because it can enhance absorption in the gastrointestinal tract, allowing entry into the bloodstream. This study aims to create and evaluate the characteristics of carica seed extract nanoparticles with varying concentrations of chitosan. The carica seed extract was obtained using the maceration method with 70% ethanol as the solvent. The Carica seed extract was then formulated into nanoparticles using the ionic gelation method with varying concentrations of chitosan: NaTPP, specifically formulas FA (0.3:1), FB (0.2:1), and FC (0.1:1). The resulting nanoparticle colloids were characterized for particle size, polydispersity index (PDI), percent transmittance (%T), and specific functional groups. The results showed that the particle sizes for formulas FA, FB, and FC were 243.7 nm, 47.96 nm, and 116.6 nm, respectively. The PDI values for formulas FA, FB, and FC were 0.378, 0.357, and 0.52, respectively. The percent transmittance for all three formulas ranged from 99.5% to 99.6%. The characterization of functional groups indicated interactions between the carica seed extract, chitosan, and NaTPP, with the presence of OH, N-H, aliphatic CH, P=O, and PO3 groups. These interactions were observed based on the shift in wavenumbers in the FTIR results for each sample. All carica seed nanoparticle formulas showed particle sizes within the nanometer range (<1000 nm), polydispersity indices less than 1, percent transmittance close to 100%, and specific functional groups indicating interactions between the extract and the coating polymer. Formula FB was the optimal formula, with the smallest nanoparticle size (<100 nm), a PDI value of <0.5, and a percent transmittance of >99%.
