“…The dye extraction from butterfly pea flowers was conducted through maceration with ethanol solvent, resulting in a yield of 55%. Multiple studies have demonstrated that this extract contains anthocyanins [24,25,26]. pH difference method was employed to determine the total anthocyanin content in the extract [9].…”

“…Additionally, another method for extracting butterfly pea flower dye involves using hot water and a 50% ethanol solvent with 1% citric acid. This method yielded total anthocyanin levels ranging between 6146.90-7925.29 mg/L, depending on the specific extraction technique employed [25]. The total anthocyanin levels obtained from butterfly pea flower dye extraction using conventional and ultrasonic-assisted extraction methods with 60% ethanol solvent were 3010.9 and 3530.2 mg/L, respectively [21].…”

A chitosan-based biofilm modified with ginger essential oil and butterfly flower extract has been made. This biofilm was tested for its potential as a raw material for smart and environmentally friendly packaging (smart and green packaging). The potential of biofilm as a packaging raw material is known from the characterization results, which include color changes at various pHs, mechanical properties, antioxidant properties, antibacterial properties, and morphological structure. The produced biofilms exhibit sensitivity to alterations in pH levels, manifesting distinct color transitions from pink and purple to green within the pH range of 1 to 12. This phenomenon arises due to adding butterfly flower extract into the biofilm, which contains anthocyanin dyes with a total concentration of 1113.3 mg/L. Adding butterfly flower extract and ginger oil contributes to an augmented biofilm thickness; however, this is accompanied by a reduction in both tensile strength and percent elongation. Concurrently, the addition of butterfly flower extract and ginger oil imparts antioxidant and antibacterial properties to the biofilm. The introduction of additional extracts enhances the antioxidant and antibacterial attributes of the biofilm. In the color and pH response assessment, the biofilm augmented with a 7.5% v/v extract exhibited a color difference value (ΔE) exceeding 5 across all assessed pH values. These findings signify the observable color variations in the biofilm due to pH fluctuations with the unaided eye. According to the outcomes of characterization and analysis, the produced biofilm holds promise as an environmentally friendly packaging solution due to its reliance on natural components and its endowed antioxidant and antibacterial properties, contributing to the prolonged preservation of packaged food items. Moreover, the biofilm demonstrates the capability to gauge the quality of food products based on their pH, which is evident through direct color alterations.

“…Results also showed that the examined medicinal plants, such as A. flagellaris, C. trigyna, G. involucrata, and P. steudneri , were positive for the anthocyanins test. Plant-based anthocyanins have antioxidant properties that play important roles in health and therapeutic effects [ 54 ]. Furthermore, the presence of phytochemicals such as alkaloids, flavonoids, glycosides, phenolic compounds, saponins, tannins, and triterpenoids promotes the anthelmintic properties of medicinal plants [ 55 ].…”

Background Medicinal plants play a major role in the delivery of healthcare, particularly among the rural population of Ethiopia. Plant extracts and their bioactive compounds have been utilized for the treatment of several diseases. This study was aimed at evaluating the antibacterial activity, antioxidant capacity, and phytochemical content of selected medicinal plants used in Dibatie district, western Ethiopia. Methods Study plants were collected, shade dried, pulverized, extracted by maceration in 80% ethanol, and subjected to antibacterial, antioxidant, and phytochemical tests. Minimum inhibitory concentration (MIC) was determined using 96-well microplates and nutrient broth microdilution. Antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. Phytochemical screening was conducted using standard test methods. Results The ethanolic extract of Polystachya steudneri Rchb.f. pseudobulbs was the most active against gram-negative Proteus mirabilis, Salmonella typhimurium, Klebsiella pneumoniae, Escherichia coli, and Shigella flexneri, with MIC values of 8 ± 0, 11 ± 5, 3 ± 1, 3 ± 1, and 2 ± 0 mg/mL, respectively. The ethanolic extract of P. steudneri was also the most effective against gram-positive Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae, and Enterococcus faecalis, with MIC values of 8 ± 0, 8 ± 0, 3 ± 1, and 16 ± 0 mg/mL, respectively. Ethanolic extracts of Gnidia involucrata Steud. ex A.Rich. stems and roots were effective antioxidants, with respective 50% DPPH free radical inhibitory concentrations (IC50) of 168.68 and 181.79 µg/mL, followed by that of P. steudneri (IC50 = 203.11 µg/mL). The study plants contained alkaloids, anthocyanins, anthraquinones, cardiac glycosides, coumarins, flavonoids, phenols, saponins, steroids, tannins, and terpenoids. Conclusions This study confirmed the antibiotic, antioxidant, and phytochemical constituents of the investigated plants and suggested further investigations that may lead to bioactive lead compounds.

Dadiah is a traditional fermented buffalo milk originating from West Sumatra, Indonesia and has health benefits. The aim of this study was to evaluate the effect of the addition of Clitoria ternatea flower extract addition (0,5%, 1%, 1,5%, and 2%) on the moisture content, hardness, total lactic acid bacteria, antioxidant activity, and total phenolic content of dadiah jelly candies. The results showed that the addition of Clitoria ternatea extract increased the moisture content, decreased the hardness value, increased the total phenolic content, and enhanced the antioxidant activity of the jelly candies. Compared to the dadiah jelly candies without Clitoria ternatea addition, jelly candies with Clitoria ternatea addition at any concentration did not differ significantly (P > 0.05) in total lactic acid bacteria, whereas the pH value increased as the concentration of the Clitoria ternatea extract increased. Overall, the use of Clitoria ternatea flower extract can improve the functional properties of dadiah jelly candies, with the best concentration of 2% of the Clitoria ternatea extract on the antioxidant activity and total phenol content.
