Abstract

Microencapsulation is a technology that uses controlled release of active ingredients to increase bioavailability and reduce gastrointestinal irritation. This study aims to evaluate the microencapsulation formulation of ethanol extract of papaya leaf (Carica papaya L.) by testing its stability, moisture content, and floating in the stomach and intestinal medium. Mardikasari et al (2020) showed the release of chitosan-alginate microencapsulation of 8,811 mg/L (acid) and 79,908 mg/L (base). Microencapsulation was performed by adding sodium alginate and chitosan as polymers, CaCl2 as a cross-linking, and three variations of extract concentration in F1 without extract, F2 of 0,25%, F3 of 0,5%, and F4 of 0,75%. The results showed that all formulas remained stable during the storage cycle in terms of color, aroma, taste, and texture. The average moisture content of the microencapsulated formulations was 24%, 20,5%, 28%, and 18,7%. The microencapsulated preparations were able to maintain their stability in the acidic conditions in the stomach, but showed a decrease in floating under acidic conditions in the intestine.

Abstract

This test aims to evaluate the formulation of floating microcapsule preparations containing ethanol extract of white turmeric (Curcuma zedoaria Rosc.), using chitosan, sodium alginate, and calcium chloride polymers as crosslinking agents. The preparation was formulated using the crosslinking method and tested based on its physical properties, which include moisture content, physical stability through cycle tests, resistance to the gastric and intestinal mucosa. The results showed that the microcapsule formulation was able to maintain the color and texture during the storage period well. The microcapsule durability test showed that the particles could survive in the gastric and intestinal mucosa for two hours. In addition, the water content is within the range that is in accordance with the requirements, namely, at a concentration of 0.25% there is (22%), a concentration of 0.5% there is (38.75%), a concentration of 0.75% there is (22.5%), and the blank has 20.5% water content. Based on previous research by Mardikasari et al., (2020) which used chitosan and alginate polymers. Through this method, this formulation shows the possibility as a technology-based drug delivery system that survives effectively in increasing the bioavailability of active substances from white turmeric.

Abstract

Bay leaf (Syzygium polyanthum (Wight) Walp.) is known to contain phenolic and flavonoid compounds with potential as natural antioxidants. This study aims to evaluate the antioxidant activity of ethanol extract of bay leaves using the DPPH method and to identify the bioactive compounds through phytochemical screening and simplicia characterization. Extraction was conducted using maceration with 80% ethanol as the solvent. Characterization result showed that the bay leaf simplicial met the standards of the Farmakope Herbal Indonesia. Phytochemical screening revealed positive results for alkaloids, flavonoids, saponins, tannins, and phenols. The antioxidant activity test showed that the ethanol extract of bay leaves had an IC50 value of 15,45 ppm, which falls into the very strong antioxidant category. These findings reinforce the potential of bay leaf as a natural antioxidant source that can be further developed in pharmaceutical and health applications.
