Isolasi, Identifikasi Senyawa Alkaloid Dan Uji Efektivitas Penghambatan Dari Ekstrak Daun Sirih (Piper betle L.) Terhadap Bakteri Staphylococcus epidermidis

Abstract: Betel leaf (Piper betle L) contains alkaloid compounds and has antibacterial and antiseptic functions. The purpose of this research was to isolated alkaloid compounds also to tested the effectiveness of inhibition of the betel leaf extract against the Staphylococcus epidermidis bacterial growth. Simplicia betel leaf was extracted used 96% of ethanol solvent. Antibacterial activity tested of betel leaf extract with a concentration variation of 25%, 20%, 15%, 10% and 5% using the liquid dilution method. The resu… Show more

“…In this study, maceration was carried out using 96% ethanol as solvent because this solvent can extract almost all simplicia content, both non-polar, semi-polar and polar. This solvent is selective, non-toxic and universal which is suitable for extracting all classes of secondary metabolites [10]. The maceration was carried out for 3x24 hours, then the maceration results were filtered and concentrated over a water bath to obtain a thick extract as shown in Fig.…”

“…Hasil identifikasi dari senyawa pada KLT dapat dilihat pada tabel 3. Hasil menunjukan adanya senyawa alkaloid yang diperoleh dari pengamatan spot noda KLT pada lampu UV λ366 yaitu adanya bercak berwana jingga ketika dielusi menggunakan kloroform : metanol (9:1) yang terlebih dahulu disemprotkan reagen Dragendrof (Kapondo et al, 2020). Identifikasi flavonoid pada pola kromatogram ditandai dengan bercak kuning setelah disemprotkan dengan AlCl3 menggunakan eluen n-heksan : etil asetat (3:7) diamati dibawah lampu UV 366 nm sebelum diuapkan didapatkan dugaan bahwa bercak tersebut adalah flavonoid (Markham, K. R. 1998).…”
