Abstract

ABSTRAKAedes aegypti merupakan serangga vektor dari virus Dengue penyebab Demam Berdarah Dengue (DBD). Kandungan senyawa dalam tumbuhan lakum berpotensi sebagai larvasida. Buah lakum dimaserasi dengan pelarut methanol kemudian difraksinasi menggunakan etil asetat. Fraksi diteliti kandungan senyawanya menggunakan analisis fitokimia. Uji larvasida diamati selama 48 jam terdiri dari tujuh konsentrasi berseri yaitu kontrol; 0,04; 0,12; 0,2; 0,6; 1; 3% (b/v). Setiap konsentrasi diulang 3 kali dan setiap ulangan terdiri dari 10 ekor larva nyamuk Ae. aegypti. Data mortalitas dianalisis menggunakan analisis probit untuk menentukan nilai LC50. Fraksi metanol buah lakum  berpotensi sebagai larvasida dengan nilai LC50 6 jam sebesar 1,125%. Fraksi etil asetat  buah lakum  berpotensi sebagai larvasida dengan nilai LC50 6 jam sebesar 1,102%. Buah lakum mengandung senyawa: polifenol, kuinon, flavonoid, alkaloid dan terpenoid. Kata kunci: Aedes aegypti; Cayratia trifolia (L.) Domin; larvasida; LC50  ABSTRACTLarvacidal activity of methanol and ethyl acetate fraction of lakum fruits (Cayratia trifolia (L.) Domin.) against Aedes aegypti larvae. Aedes aegypti is a vector from the Dengue virus which causes Dengue Hemorrhagic Fever (DHF). The compounds of lakum plants has the potential larvicide. The fruit of C. trifolia was macerated with methanol then fractionated using ethyl acetate as a solvent. The fraction was examined for its compound using phytochemical analysis. Larvacide test was observed for 48 hours consisting of seven concentration of 0 (control); 0.04; 0.12; 0.2; 0.6; 1; 3% (w/v). Each concentration was repeated 3 times and each repetition consisted of 10 larvae of Ae. aegypti. Mortality data were analyzed using probit analysis to determine the LC50 of the fraction of methanol and ethyl acetate from lakum fruit. The methanol fraction has the potential larvicide with a six hour LC50 value 1.125%. The ethyl acetate fraction has the potential larvicide with a six hour LC50 value 1.102%. The C. trifolia fruits contains polyphenols, quinones, flavonoids, alkaloids and terpenoids. Keywords: Aedes aegypti; Cayratia trifolia (L.) Domin.; larvacide, LC50

Abstract

Paracetamol metabolism takes place in the liver mediated by CYP450 enzymes and generates NAPQI radicals. The NAPQI radical is highly electrophilic to hepatocyte biomolecules and is therefore capable of inducing liver damage. Laban tree bark (V. pubescens) methanol extract is known to contain antioxidant compounds of flavonoids, saponins, and tannins with an IC50 value of 19.83 g/ml. This study aims to determine the optimal dose of extract that can improve the liver microanatomy of mice induced by toxic dose of paracetamol (TDP). This study used 30 male Swiss strain mice with a body weight of 20-30 g. The treatments given consisted of negative control (paracetamol 105 mg kg-1), positive control (vitamin E 46.8 mg kg-1), and laban extract at a dose of 75; 150; 300; 600 mg kg-1 BW. Liver microanatomy parameters measured included hepatocyte diameter (19.50±0.21 µm), sinusoids (4.39±0.23 µm), and central vein (36.84 ± 1.79 µm). Data were analyzed using one-way ANOVA and Duncan's Multiple Range Test further test was then presented in the form of mean ± standard deviation. The results showed that extract at a dose of 600 mg kg-1 had hepatocyte, sinusoid, and central vein diameters that were not significantly different (p>0.05) with vitamin E.
