Optimalisasi Ekstraksi dan Uji Metabolit Sekunder Tumbuhan Libo (Ficus variegate Blume)

Abstract

Libo leaves (Ficus variegate Blume) is never eaten by caterpillars. This is indicated that libo leaves has a good secondary metabolites. This research was conducted on optimization of extraction techniques and test of secondary metabolites of leaves Libo. The optimization was done by changing variables viz. method of extraction, variation of amount of solvent, and duration of extraction. The effectiveness of extraction was seen from % of yield. Method of extraction was using maceration and soxhlet. Methanol was used as

“…Sampel selanjutnya dimaserasi dengan pelarut metanol 96% dengan perbandingan 1:10. Seluruh filtrat yang dihasilkan, kemudian dipekatkan dengan metode penguapan sederhana dengan suhu dibawah 60 o C (Febrina, 2015).…”

The Effect of Giving Croton Leaf Crude Extract (Codiaeum variegatum) as an Alternative to The Antibacterial of Edwardsiella tarda in Vitro

“…The extraction process is an important first step in medicinal plant research because the plant extract preparation is the starting point for the isolation and purification of the chemical components contained in plants. Dry simplicial that has been mashed is then extracted by maceration using 96% ethanol solvent (Febrina et al, 2015). By the research of Ogunwenmo et al (2007), where 500 grams of croton leaf powder is put into 2 jars, in each jar is filled with 250 grams of croton leaf powder and soaked using 96% ethanol solvent with a ratio of 1: 10 as much as 5 liters with each jar filled 2.5 liters for 2 x 24 hours at room temperature (27 -30ºC).…”

Peningkatan Kelarutan Ekstrak dan Fraksi Buah Libo (Ficus variegata Blume) dengan Pengaruh Penambahan Kosolven

“…Semua bagian dari libo diduga memiliki potensi aktivitas, karena diketahui mengandung metabolit sekunder berupa flavonoid, alkaloid, steroid, terpenoid, saponin dan fenol (Febrina, 2015). Potensi aktivitas pada bagian daun baik pada ekstrak maupun berbagai fraksi seperti yang telah dilaporkan oleh Cahya (2016), Novitasari (2016), Rusli (2016) dan Nurtiwi (2016), pada bagian kulit batang seperti dilaporkan oleh Utami (2016) dan Saleh (2016), serta pada bagian buah Ningsih (2016) dan isolatnya (Rusli, 2019).…”
