Judul: Potensi Antihiperkolesterolemia Ekstrak Seduhan Teh Herbal Lempuyang Gajah (Zingiber zerumbet L.)
Abstrak: The objective of this research was to study the effectivity of herbal tea compositions of lempuyang gajah as antihypercholesterolemic agent. Extracts were tested in Sprague-Dawley male rats. Forty six rats were divided into four experimental groups as follow: normal, hyperlipidemic, herbal tea extract 1, and herbal tea extract 2. Rats were made hiperlipidemic by oral administration of propil tiouracil (0.5 mg/Kg BW) and high cholesterol feeding (1.5 % cholesterol). Total blood cholesterol concentrations were measured by cholesterol oxidase enzymatic methods of ‘CHOD-PAP’ using spectrophotometer at wavelenght 500 nm. Results showed that cholesterol diet increased blood cholesterol concentration by 76.11 % (p=0.004). Following free cholesterol diet (washed out period), blood cholesterol concentration was decreased by 43.82 % (p=0.101). Similarly, extract 1 reduced cholesterol concentration by 43.20 % (p=0.005). Antihyperlipidemic potency of extract 2 is higher than extract 1 as shown by significant reduction of cholesterol by 51.70 % (p=0.000).

Twenty six rats were divided into normal group and cholesterol feed group. Cholesterol feed group (HK) were divided into 3 groups: hypercholesterolemic (HK I), herbal tea dosage 1 (HK II), herbal tea dosage 2 (HK III). Hypercholesterolemia was induced by cholesterol diet (1.5%) and PTU (0.01%) administered orally for 6 weeks. Afterward, animals were given cholesterol free standard diet. Extract of herbal tea were administered orally for another 4 weeks with dosage of lempuyang gajah:green tea= 1:2 (dosage 1) and 2.5:2 (dosage 2). Lipid peroxide concentration was analyzed in week-0,2,4,6,8, and 10 using spectrophotometry method at 533 nm. Cholesterol fat and PTU induction significantly (p<0.05) increased lipid peroxide concentration in blood of HK (40.31%) compared with normal group.
