Binahong leaves contain active compounds such as alkaloids, steroids, flavonoids, phenols, saponins, tannins. The content of active substances in binahong leaves can be extracted by maceration. 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 types of solvents on the yield of binahong leaves. The research method used was Postest Only Group Design. The extraction method of binahong leaf simplisia was carried out using 2 types of solvents, namely 96% ethanol and n-hexanes. The extract obtained was then evaporated until a thick extract was obtained and then the yield value of each solvent was calculated. Data from the yield value was tested using the SPSS 25 program with a confidence level of 95%. Normality test was conducted with Shapiro Wilk test and homogeneity test using Levene, normally distributed and homogeneous data resulted (sig>0.05) followed by Independet T-test to determine the effect of different types of solvents. Data that were not normally distributed and homogeneous resulted in (sig0.05) were analyzed using the Mann Whitney test.

Turmeric rhizome is one of the herbal medicinal plants that is easily found in Indonesia. Turmeric rhizome has secondary metabolite compounds which are efficacious as antibacterial, anti-inflammatory, anti-diarrheal, antioxidant, and appetite enhancer. Secondary metabolites were obtained from various extraction methods. The purpose of this study was conducted to determine the effect of different extraction methods on the content of secondary metabolites in turmeric rhizome extract.
This research was conducted using the Post-test Only Design experimental method. Fine powder of turmeric rhizome was extracted using maceration and soxhlet methods with 70% ethanol solvent. The turmeric rhizome extract was then subjected to a phytochemical screening test including phenolic, alkaloid, flavonoid, terpenoid, saponin and tannin tests. The results of the data obtained are presented in the form of a table containing results and information then compared with the Indonesian Herbal Formulary II Edition and previous studies.

Daun mengkudu memiliki salah satu senyawa antrakuinon yang dapat dihasilkan dari proses ekstraksi maserasi. Perbedaan pelarut mempengaruhi efektivitas pada proses ekstraksi yang ditunjukkan dengan perolehan nilai rendemen. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan pelarut ekstraksi terhadap nilai rendemen dari ekstrak daun mengkudu.
Penelitian ini dilakukan menggunakan metode eksperimental dengan Posttest Only Design. Serbuk daun mengkudu di ekstraksi secara maserasi dengan 3 pelarut yaitu etanol 96%, etil asetat, dan n-heksan. Filtrat hasil maserat diuapkan dengan kering angin. Ekstrak yang diperoleh dihitung rendemennya dan dianalisis menggunakan SPSS dengan taraf kepercayaan 95%. Uji normalitas data dilakukan menggunakan Shapiro Wilk dan uji homogenitas data menggunakan Levene. Data terdistribusi normal dan homogen (p>0,05), lalu dilakukan uji One Way Anova. Apabila hasil uji One Way Anova diperoleh nilai signifikansi p<0,05 dilanjutkan dengan uji Post hoc LSD. Jika data tidak terdistribusi normal dan tidak homogen (p<0,05), kemudian dilakukan uji Kruskal Wallis. Apabila hasil uji Kruskal Wallis diperoleh nilai signifikansi p<0,05 dilanjutkan dengan uji Mann Whitney.
