Katuk leaves contain chemical compounds such as alkaloids, tannins, flavonoids, saponins and steroids. Extraction of a plant can affect the yield and chemical content. The purpose of this study was to determine the effect of different extraction methods on the yield and chemical content of katuk leaf extract. This research method uses Post-test Only Design and the extraction used is maceration and soxhlet, with 96% ethanol solvent. 50 g of simplisia powder was macerated with solvent in a ratio of 1:10 for 3x24 hours. Soxhlet extraction is carried out until the liquid is no longer colored. The filtrate obtained was evaporated and air dried until a thick extract was obtained. The extracts obtained from each extraction method were calculated for yield and chemical content. The yield was calculated statistically with the Shapiro-Wilk normality test. If the data is normal and homogeneous , the Independent Sample T-Test test is continued, if the data is not normal and not homogeneous, the Mann-Whitney test is continued. While the chemical content is descriptive.

Katuk leaves contain chemical compounds such as alkaloids, tannins, flavonoids, saponins, triterpenoids, polyphenols, steroids, quinones, monoterpenoids and sesquiterpenoids. Factors that influence the yield and chemical content of katuk leaf extract are differences in the type of solvent. The aim of this research was to determine the effect of the type of extraction solvent on the yield value and chemical content of katuk leaf extract. The extraction method used in this research was maceration, using 96% ethanol and n-hexane as solvents. Simplicia powder is macerated with each solvent (ratio 1:3) for 3 x 24 hours with stirring 15 minutes every 24 hours. The maceration results obtained were then filtered and air dried until a thick extract was obtained, then the yield value and chemical content of the katuk leaf extract were tested. Data from the results were analyzed using SPSS with the Shapiro Wilk normality test and Levene's homogeneity test with a confidence level of 95%. The yield value data was then subjected to an Independent Sample T-test to determine the influence between groups of solvent types.

The yield is obtained from the thick extract of basil leaves in maceration. Maceration is done using different solvents. The choice of solvent type affects the yield value of the extraction results. The purpose of this study was to determine the effect of different solvents on the yield value of basil leaf extract.
This type of research uses experimental posttest only design. The extract was carried out by maceration method using 96% ethanol and n-hexane solvents for 3 × 24 hours each. After soaking the basil leaf extract was dried using a waterbath with a temperature of 600 C. After drying, the yield value was calculated. The yield data were analyzed using SPSS version 26. The yield data obtained were first tested for normality and homogeneity using the Shapiro Wilk test. Normally distributed data with significant (sig) > 0.05 was followed by an independent t-test to compare between groups of solvent types.
