Daftar Isi:
- Stenochlaena palustris dikenal dengan nama lokal pucuk iding-iding bagi masyarakat Bangka Belitung. Pemanfaatan Stenochlaena palustris sebagai obat tradisional untuk mengobati bisul, penyakit kulit, dan penambah darah. Pada penelitian ini telah dikaji kandungan metabolit sekunder dan potensi antibakteri pada Stenochlaena palustris. Serbuk kering Stenochlaena palustris dimaserasi menggunakan etanol, dan aktivitas antibakteri ditentukan menggunakan metode difusi cakram terhadap bakteri Staphylococcus aureus , Escherichia coli, dan Bacillus subtilis. Berdasarkan hasil skrining fitokimia ditemukan flavonoid, alkaloid, saponin, dan fenol hidrokuinon pada ekstrak etanol Stenochlaena palustris. Hasil pengujian antibakteri didapatkan daya hambat ekstrak etanol Stenochlaena palustris tergolong sedang dalam menghambat pertumbuhan bakteri E. coli dan B. Subtilis pada konsentrasi 50 mg/mL dengan diameter zona bening masing-masing 5,28 mm dan 6,00 mm. Daya hambat terhadap pertumbuhan S. aureus pada konsentrasi 50 mg/mL dengan diameter zona bening sebesar 4,38 mg/mL tergolong lemah.
- Stenochlaena palustris locally known as pucuk iding-iding for the people of Bangka Belitung. Stenochlaena palustris is used as traditional medicine for the treatment of ulcers, skin diseases, and blood boosters. In this research we have studied the secondary metabolite and antibacterial property of Stenochlaena palustris. The dried powder of Stenochlaena palustris were macerated with ethanol, and the antibacterial activity was determined using paper disc method against Staphylococcus aureus, Escherichia coli, and Bacillus subtilis. The phytochemical screening indicated the presence of flavonoids, alkaloids, saponins, and phenol hidrokuinon on ethanolic Stenochlaena palustris extract. The ethanolic Stenochlaena palustris extract inhibited the growth of E. coli and B. Subtilis at concentration 50 mg/mL with diameter clear zone 5,28 mm and 6,00 mm this inhibition was classified as moderat. inhibition of S. aureus at concentration 50 mg/mL with diameter clear zone 4.38 mg/mL was classified as weak.
