Ploceus Philippinus

Penelitian tentang karakteristik sarang tempua Ploceus Philippinus di area persawahan Gurun Aur, Kecamatan Banuhampu, Kabupaten Agam, Sumatera Barat, telah dilaksanakan dari bulan Maret sampai Mei 2016 dengan metode survey langsung. Tujuan dari penelitian ini adalah untuk mendeskripsikan karakteristik dan material penyusun sarang. Dari hasil penelitian ini diketahui bahwa bentuk sarang burung tempua secara umum menyerupai pendulum di pelepah daun pohon kelapa dengan rata-rata tinggi sarang 7,81 m dari permukaan tanah. Sarang mengantung di pelapah pohon kelapa dengan pintu masuk dari bawah.Bentuk sarang yang belum lengkap juga ditemukan jika burung gagal mendapatkan pasangan. Sarang ini menyerupai kubah berbeda dengan sarang yang telah lengkap berbentuk seperti kantung dengan variasi lonjong dan bentuk ginjal. Sarang juga memiliki nilai yang bervariasi pada ukuran panjang, berat dan tinggi gantungan. Bahan yang digunakan burung tempua membangun sarang sebagian besar dari potongan rumput (Graminae) dan malai tumbuhan Imperata cylindrica untuk alas chamber (ruang telur).

Potential Origin

The local botanical Imperata cylindrica in Cameroon was investigated for its antibacterial potency. The methanol extract afforded a total of seven compounds, including five hitherto unreported compounds comprising three flavonoids (1–3) and two C-15 isoprenoid analogues (4 and 5) together with known derivatives (6 and 7). The novelty of the flavonoids was related to the presence of both methyl and prenyl groups. The potential origin of the methyl in the flavonoids is discussed, as well as the chemophenetic significance of our findings. Isolation was performed over repeated silica gel and Sephadex LH-20 column chromatography and the structures were elucidated by (NMR and MS). The crude methanol extract and isolated compounds showed considerable antibacterial potency against a panel of multi-drug resistant (MDR) bacterial strains. The best MIC values were obtained with compound (2) against S. aureus ATCC 25923 (32 µg/mL) and MRSA1 (16 µg/mL).
