Abstract

Melastoma affine D. Don had some activities such as anthelmintic, antibacteria, antiinfiammation, antifungal, and antitumor. The aims of this research was determine antibacteria activity of ethanolic extract of Melastoma affine D. Don. The antimicrobial activity was tested by solid dilution method to get Minimum Inhibition Concentration (MIC). The compounds in Melastoma affine D. Don was analyzed by tube test method and Thin Layer Chromatography (TLC) with chloroform : methanol : formic acid (8,5:1,5:0,5) as mobile phase and silica gel GF254 as stationary phase. The result showed ethanolic extract of Melastoma affine D. Don contains alkaloid, polyphenol, fiavonoid, saponin, and essential oil. The MIC of Senggani against Staphylococcus aureus was 2% and 3% against Escherichia coli and the extract could not inhibit Staphylococcus aureus and Escherichia coli multiresistant until concentration 7% extract ethanol.Keywords: Melastoma affine D. Don, Staphylococcus aureus, Escherichia coli

Abstract

The ethanolic extract of Anacardium occidentale L. leaves contains phenolic compounds,  avonoids, alkaloids, saponins, tannins, and steroids that could have antioxidant activity. The aim of this research was to determine the correlation between the antioxidant activity and the phenolic compounds of the ethanol extract of Anacardium occidentale L. leaf. The DPPH methode was used to determine the antioxidant activity. The total phenolic determined using Folin-Ciocalteu reagent. There was a positive correlation between antioxidant activity and total phenolic content in the ethanolic extract of cashew leaf with correlation coef cient R2 = 0.5888.Keywords: Anacardium occidentale L., antioxidant, phenolic compounds

Abstract

Radikal bebas merupakan satu faktor kontributor terjadinya penyakit degenerative. Antioksidan merupakan senyawa yang menghambat efek radikal bebas tersebut. Pada penelitian sebelumnya, ekstrak methanol daun Daun salam mempunyai efek antioksidan. Penelitian ini bertujuan menguji efek antioksidan ekstrak ethanol 70% daun salam (Syzygium polyanthum (Wight)). Metode yang digunakan adalah uji invitro dengan metode DPPH (Diphenyl picrylhydrazyl). Ekstrak dilarutkan dalam ethanol, kemudian dibuat dalam seri konsentrasi 10, 30, 50 dan 70 ug/mL. Masing-masing seri sebanyak 10 ml. Dalam masing-masing larutan tersebut ditambahkan 1 ml larutan DPPH 1 mM. larutan kemudian diinkubasi pada suhu 37°C selama 30 menit. Panjang gelombang yang digunakan adalah 515 nm. Metanol dan DPPH 1mM digunakan sebagai blanko.Untuk pembanding digunakan butylated hydroxytoluene (BHT) konsentrasi 2, 4, 6, 8 ug/mL. Hasil penelitian menunjukkan bahwa ekstrak ethanol 70% daun salam mempunyai efek antioksidan dengan IC 50 27,80 ug/mL.Kata kunci: daun salam (Syzygium polyanthum (Wight) , antioksidan, IC 50
