ABSTRAK Minuman rebusan daun salam yang mengandung ekstrak kayu manis diketahui mengandung senyawa biokimia flavonoid dan asam sinamat yang dikenal memiliki aktivitas menurunkan kadar kolesterol. Penelitian ini dilakukan untuk mengetahui pengaruh penambahan ekstrak kayu pada minuman fungsional rebusan daun salam terhadap penurunan kadar kolesterol darah tikus. Penelitian ini terdiri dari 2 (dua) tahap yaitu pembuatan minuman fungsional air rebusan daun salam dengan penambahan ekstrak kayu manis dan pengujian efek hipokolesterol dengan minuman rebusan daun salam yang mengandung ekstrak kayu manis secara in-vivo pada tikus percobaan. Kelompok tikus diberikan 5 perlakuan yaitu pemberian akuades, pemberian minuman rebusan daun salam dengan penambahan ekstrak kayu manis 100, 200, 300 mg, dan pemberian sediaan pembanding gemfibrozil dosis 21,6 mg/200 g bb/hari.
