ekstrak limpasu (Baccaurea lanceolata), aktivitas antibakteri, penapisan fitokimiaAbstract
Limpasu merupakan tanaman yang berlimpah dari Kalimantan Selatan. Data empiris menunjukkan buah limpasu berpotensi untuk mengobati demam (karena infeksi), kesehatan kulit, dan antioksidan. Data ilmiah pendukung potensi limpasu sebagai anti-infeksi yang disebabkan bakteri masih minim. Penelitian ini bertujuan mendapatkan data ilmiah kandungan kimia secara kualitatif dan potensi ekstrak limpasu sebagai antibakteri. Bagian buah, daun, dan kulit batang limpasu diekstraksi menggunakan pelarut etanol 96% dengan soxhlet. Ekstrak cair diuapkan menggunakan rotary evaporator sehingga didapatkan ekstrak buah (EB), ekstrak daun (ED), dan ekstrak kulit batang limpasu (EKB). Pengujian aktivitas antibakteri dilakukan dengan metode difusi padat menggunakan kertas cakram. Bakteri yang diuji terdiri dari Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Propionibacterium acnes, dan Staphylococcus epidermidis. Hasil penelitian menunjukkan, ekstrak etanol buah limpasu merupakan ekstrak yang paling aktif terhadap bakteri B. subtilis, S. aureus, P. aeruginosa, E.coli, dan P. acnes dengan konsentrasi hambat minimum adalah 2,5% b/v dengan diameter secara berturut-turut 6,87; 7,60; 7,94; 8,80; dan 10,29 mm. Ekstrak etanol buah, daun, dan kulit batang limpasu secara umum positif mengandung alkaloid, flavonoid, tanin, dan saponin.
