POTENSI DAUN RUMPUT BELANG SEBAGAI OBAT TRADISIONAL YANG BERKHASIAT ANTIMIKROBA
Main Article Content
ABSTRAK
Telah dilakukan penelitian tentang pengujian ekstrak etanol dari daun rumput belang terhadap pertumbuhan Staphylococcus aureus, Escherichia coli dan Shigella dysenteriae. Rumput belang (Zebrina pendula Schnizl.) merupakan tanaman hias yang budidayanya sangat mudah sehingga tanaman ini dapat ditemukan didataran rendah maupun dataran tinggi. Secara empiris memiliki rumput belang memiliki khasiat antara lain untuk mengatasi disentri dan bisul. Hasil pengujian ekstrak etanol 96 % terhadap Staphylococcus aureus memberikan hambatan terbesar pada konsentrasi 60% = 11,69±0,57 (mm), Escherichia coli memberikan hambatan terbesar pada konsentrasi 80% = 12,83±0,68 (mm), Shigella dysenteriae memberikan hambatan terbesar pada konsentrasi 80% = 12,81±0,43 (mm). Hasil pemeriksaan golongan kandungan kimia pada ekstrak daun rumput belang terdapat flavonoid, polifenol, kuinon, monoterpenoid-seskuiterpenoid dan senyawa steroid-triterpenoid.

ABSTRACT
A research on the testing of the ethanol extract of the leaves of rumput belang on the growth of Staphylococcus aureus, Escherichia coli and Shigella dysenteriae. Striped grass (Zebrina pendula Schnizl.) Is an ornamental plant cultivation is very easy so that the plant can be found in lowland and highland. Empirically the leaves of rumput belang have properties among others, to overcome dysentery and ulcers. Results of testing the 96% ethanol extract against Staphylococcus aureus provide the biggest obstacle at a concentration of 60% = 11.69 ± 0.57 (mm), Escherichia coli provide the biggest obstacle at a concentration of 80% = 12.83 ± 0.68 (mm), Shigella dysenteriae provide the biggest obstacle at a concentration of 80% = 12.81 ± 0.43 (mm). Class examination results of chemical constituents in the leaves of rumput belang extracts are flavonoids, polyphenols, quinones, monoterpenoid-sesquiterpenoids and steroid-triterpenoid compounds.
Keywords : the leaves of rumput belang, Staphylococcus aureus, Escherichia coli and Shigella dysenteriae
