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.

Abstract

Celery (Apium graveolens L.) is an herbal plant containing bioactive compounds such as flavonoids, alkaloids, tannins, saponins, and triterpenoids that have the potential to lower blood glucose levels. However, the stability and absorption of its active compounds still need to be developed. One effort to improve the stability and effectiveness of the extract is through microencapsulation technology. This study aims to formulate and evaluate the physical characteristics of microencapsulated preparations containing celery herb ethanol extract. The method used includes making the extract by maceration technique using 80% ethanol, then formulation using alginate and chitosan polymers with ionic gelation method using CaCl2 solution. Evaluation of the preparation includes stability test, water content and adhesion test on the gastric mucosa. The results showed that the microcapsules remained stable, there were no physical changes after six cycles. The adhesion test showed that the extract concentration of 0% (blank) had the highest adhesion ability and the lowest water content was 0.25%.

Abstract

Ethanol extract of bay leaves is known to have pharmacological activities such as anti-inflammatory, antihypertensive, and antidiabetic. However, its stability and solubility are still challenges. Therefore, a microencapsulation-based delivery system with floating characteristics that can last longer in the stomach was developed. This study aims to evaluate floating microencapsulation preparations containing ethanol extract of bay leaves (Syzygium polyanthum) as an effort to increase the effectiveness and bioavailability of active substances orally. The results showed that microencapsulation had a total floating of more than 4 hours with a water content of 0.47% -2.14%. Stability tests showed no significant changes in physical and chemical characteristics after cycling tests.
