Secondary metabolites are compounds produced by plants, microorganisms and animals through the process of biosynthesis or derivatives from primary metabolites. The maceration method is a simple way to separate bioactive compounds from plant material. Guava leaves contain secondary metabolite compounds which have medicinal effects such as antibacterial, antioxidant and anti-inflammatory. This simplicia leaf is soaked in 96% ethanol (using the maceration method) for 24 hours and concentrated using a rotary evaporator. Alkaloid, flavonoid and saponin tests show that guava leaves contain these three compounds. These compounds have potential for development in the pharmaceutical field.

Gangrenous wounds are wounds that occur due to diabetes complications caused by nerve damage and poor blood circulation which makes diabetic wounds unable to prevent infection. Infection is caused by the growth of microbes. High levels of sugar in the blood of DM sufferers provide food for microbes to reproduce.

Blood sugar levels, or blood glucose levels, are crucial for overall health and are regulated by the pancreas through insulin. Normal blood sugar levels range between 70-99 mg/dL when fasting and up to 140 mg/dL two hours after eating. Abnormal blood sugar levels can suggest a variety of health issues, including hypoglycemia (low blood sugar levels caused by excess insulin, certain drugs, or illnesses such as diabetes) and hyperglycemia (high blood sugar levels associated with diabetes). Regular blood sugar monitoring is necessary, especially for diabetics. Guava, a tropical fruit, includes a variety of phytochemicals that have been linked to pharmacological benefits such as antibacterial capabilities. This research uses an extraction process involving solid-liquid extraction or maceration, with methanol being the optimal solvent. The extract yields 9.51%. Wistar rats are used to investigate its antidiabetic efficacy. The rats are divided into three groups: positive control, negative control, and extract treatment. Diabetes is induced by subcutaneous injection of Alloxan, followed by oral administration of the methanol extract. Blood glucose levels are assessed after fasting for 6-8 hours. The extract from dried Guava leaf powder yields a concentrated extract with a 9.51% yield. In vivo assessments showed a significant reduction in blood glucose levels in rats treated with guava leaf extract, suggesting potential anti-hyperglycemic effects. The phenolic compounds in guava leaves contribute to antioxidant and anti-hyperglycemic effects. The study highlights the potential therapeutic effects of guava mint leaves and their extract components for diabetes management and antioxidant health benefits.
