Abstract

Shallots (Allium cepa L.) are plants from the Amaryllidaceae family, Allioieae subfamily, and Allium genus. This perennial plant is estimated to have more than 1,000 species. Shallot leaves form a basal sheath. Biofertilizer contains rhizobacteria, which facilitate nutrient availability and uptake by plants. This research was conducted to determine the effect of biofertilizers on the physiological conditions and anatomical structure of shallot leaves (A. cepa L.) under drought-stress conditions. The treatments applied included the provision of biofertilizer and different drought stresses; biofertilizer was used with concentrations (10, 15, and 20 L/Ha), and the drought stress applied was 25, 50, and 75%. Data from measurements of chlorophyll a and chlorophyll b levels, Membrane Stability Index (MSI), stomatal density, leaf thickness, and metaxylem diameter were analyzed using SPSS 20, ANOVA test, DMRT with a confidence level of 95%. A biofertilizer concentration of 10 L/Ha is optimal for the Membrane Stability Index (MSI), a concentration of 15 L/Ha is optimal for chlorophyll a and b levels, leaf thickness, and metaxylem diameter, and a concentration of 20 L/Ha is optimal for increasing stomata density shallot leeks under drought stress conditions.

Abstract

Mulberry leaves (Morus alba Linn.) are a plant whose potential has been widely studied because it contains phytochemical compounds such as flavonoids and phenols which have various health benefits. This plant belongs to the Moraceae family and has the characteristics of a woody trunk, branches and brown bark with a height of between 5 and 10 meters, has oval or heart-shaped leaves with tapered tips, and has oval-shaped fruit that is black when ripe. This research aims to analyze chemical compounds in mulberry leaf extract (Morus alba L.) using spectrophotometric methods. Phytochemical screening showed positive results for flavonoids (Shinoda and NaOH test), alkaloids (Wagner and Dragendorff test), tannins (Braymer's solution and base) test, and steroids (Salkowski test). UV-Vis spectrophotometric analysis at a wavelength of 200-800 nm shows maximum absorption at 786 nm for the 10-2 dilution sample. Analysis of total flavonoid content using standard quercetin showed concentrations of 50.06 mg/g and 52.87 mg/g for the 1000 ppm and 500 ppm samples, respectively. The extract yield was 29.086%, with a water content of 4.415% and an ash content of 0.1%. These findings indicate that mulberry leaf extract contains various bioactive compounds with potential pharmacological properties, especially flavonoids which can be useful for medicinal applications.
