Abstract

Blood cholesterol levels wh ich were higher than normal is trigger of various diseases. The objective of the research was to know “The Effect of Mackerel (Scomberomorus co mmerson) in the Feed to the Decline in Blood Cholesterol Levels in Hypercholesterolemic Male Mice (Mus musculus). The study was conducted over 40 days using completely randomized design with treatments, the positive control, negative control, and the mice were given the addition of mackerel on a standard feed with 3 different levels so grouped in L1 (2:1); L2 (1:1) and L3 (1:2). The parameters measured are total cholesterol blood serum of mice with the CHOD-PAP method. Cholesterol levels are measured with a photometer 5010 at a wavelength of 500 nm. The result in the (-) 86 mg/d L; (+) 113 mg/d L; L1 102 mg/d L; L2 86 mg/dL; and L3 82 mg/dL.

Abstract

The aim of this study was to determine the antio xidant and toxicity act ivities of n-hexane and ethyl acetate of Piper aduncum L. (family : Piperaceae). Antio xidant activities of the ext racts was assessed by means of DPPH free radical scavenging method used ascorbic acid as standard with IC 50 value was 4,841 μg/mL. Piper aduncum L. showed n-hexane extract demonstrated the good antioxidant activity with IC 50 value of 40,034 μg/ mL and the ethyl acetate extract is 59,838 μg/ mL. The Brine shrimp letality bioassay met od as sed to determine t e cytotoxicity activities. The LC 50 values of n-hexane and ethyl acetate extracts were 25,12 and 17,78 μg/ mL, respectively.

Abstract

Telah dilakukan penelitian isolasi dan identifikasi senyawa kimia dari ekstrak n-heksan batang benalu tanaman jeruk (Dendrophtoe pentandra (L.) Miq.). Penelitian ini dilakukan dengan metode maserasi dengan pelarut n-heksan, etil asetat, etanol dan air, uji fitokimia, uji mortalitas larva udang dengan metode BSLT (Brine Shrimp Lethality Test) serta isolasi dengan kromatografi kolom dan identifikasi dengan menggunakan spektrofotometer Fourier Transform Infra Red (FT-IR) dan Kromatografi Gas – Spektrometri Massa (KG-SM). Dari hasil uji mortalitas larva udang didapatkan bahwa ekstrak n-heksan adalah ekstrak yang paling aktif kemudian dilanjutkan pada proses isolasi dan diperoleh isolat n-heksan 3.2 yang memiliki nilai toksisitas (LC50) sebesar 92,197 ppm. Berdasarkan hasil analisis dengan spektrofotometer FT-IR dan KG-SM senyawa kimia yang diduga terdapat dalam ekstrak n-heksan batang benalu tanaman jeruk (Dendrophtoe pentandra (L.) Miq.) adalah senyawa Stigmasterol.

Abstract

Phytochemical test and antihyperglicemic activity from ethanol extract dan n-hexane extract from kembang bulan (Tithonia diversifolia A.Gray) leaf has been carried out. Based on the test result of phytochemistry of secondary metabolites compounds from kembang bulan (Tithonia diversifolia A.Gray) leaf showed that ethanol extract fraction containing flavonoid, fenolik, alkaloid and saponin. Whereas at n-hexane extract fraction containing alkaloid, saponin and steroid. Antihyperglicemic activity test using the method of glucose tolerance where a white male rats got induced by sucrose. Measurement of blood sugar levels using glucometer and glucose test strip. From this test shows that the most active fractions to reduce blood sugar levels was ethanol extract with a dose of 77 mg/kg BB with percentage of blood sugar levels reduction in the amount of 54.15 % it was close with reduction percentage from acarbose as positive control in the amount of 55.57 %.

Abstract

The research about utilization of ethanol extract form leafkecapi (Sandoricum koetjape (Burm.f.)Merr.)has been done, it proved could decrease  total cholesterol levels in male mice (Mus musculus). In this research sample macerated with ethanol 96% and then concentrated by rotary evaporator, and gained 15.6% of yield. Based on the results of phytochemical test, secondary metabolites compound that contained in bark kecapi are alkaloid, flavonoid, triterpenoid, steroid, phenolic and saponin. On antihiperkolesterolemia activity test by using male mice, there are several treatments that negative control (-), positive control (+) and three treatment with different doses i.e. a low doses (9.5 mg/kg BB), middle doses (19 mg/kg BB) and high doses (38 mg/kg BB). The parameter measured was blood serum of male mice by using a Cholesterol Test Strips. From this test it showed that the effectiveness of decreased total cholesterol level doses of 19 mg/kg BB showed total cholesterol level under 100 mg/dL. Keywords:      Leaf kecapi (Sandoricum koetjape (Burm.f.) Merr.), Phytochemicals test, Total cholesterol levels, Cholesterol test strips.

Abstract

The structure modeling of zeolite A using calculation of molecular mechanics methods with variation of Si/Al ratio ( 1; 1,18; 1,4; 1,66 and 2) and variation of cations (Li+, Na+, K+) has been investigated. The result shows that the structure of zeolit A with the ratio of Si/Al = 2, has the most stable structure with a minimum energy 1757,1420 kcal/mol. The most stable zeolite A structure impregnated with cations are determined from the lowest energy which is 1686,8383 kcal/mol for the structure with K+ cation. In addition result shows that the structure with Li+ cation has the largest window diameter, thus affecting the window size of the zeolite A structure of which potentially has the best adsorbent capacity.
