Hasil penelitian menunjukkan bahwa kandungan senyawa fenolat total fraksi n-heksana , yaitu 45,04 mg ekuivalen asam galat/gram fraksi kering. Sedangkan kandungan flavonoid total fraksi n-heksana yaitu 5,58 mg ekuivalen kuersetin/gram fraksi kering. Aktivitas antioksidan dengan metode DPPH diperoleh IC 50 yaitu 13485 ppm. Identifikasi dari golongan kumarin dari kromatografi kolom dihasilkan 11 fraksi, berdasarkan hasil profil KLT setelah disemprot dengan pereaksi warna NH 3 dan dilihat di bawah lampu UV 365 nm, ditunjukkan bahwa fraksi F 1 positif mengandung golongan senyawa kumarin yang ditunjukkan oleh noda berwarna hijau kuning. Bagaimanapun struktur kimia dari senyawa tersebut hingga saat ini belum dapat diusulkan.}, issn = {2597-9914}, pages = {27--32} doi = {10.14710/jksa.16.1.27-32}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/17917} }
