Context: High cholesterol in the blood is a risk factor for atherosclerosis that causes various diseases. The main pharmacologic intervention to reduce cholesterol levels is inhibiting the HMG-CoA reductase enzyme. One of the genera of Garcinia, Garcinia dulcis, has potential as an anti-cholesterol. Based on chemotaxonomy, Garcinia latissima Miq. is also estimated to have a potency as anti-cholesterol. Aims: This study aims to test the inhibition of HMG-CoA reductase water extract activity of G. latissima fruit flesh with different duration of infusions. Materials and Methods: Garcinia latissima Miq. mesocarp was extracted using infusion method with different duration of infusions. Each of extracts was tested the inhibitory activity of HMG-CoA reductase as well as the determination of total flavonoid and total phenol content. In addition, the simplicia of the mesocarp of G.latissima Miq. will be made as a herbal tea and a hedonic test is performed to find out the degree of liking for the tea. Result: The test results showed the inhibitory activity of 100 ppm G. latissima Miq. mesocarp water extract with infusion for 5, 10 and 15 min respectively 11.32; 29.02; 13.03\%. The 10 min extract with the largest enzyme inhibition had total flavonoids content of 31.24 mg QE / gram extract and total phenol content of 4.64 mg GAE/ gram extract. The result of the hedonic test for the colour, aroma, flavour of herbal tea formula A respectively 30; 30; 20\% and formula B respectively for 40; 33.3; 50\%. Conclusion: The water extract of G.latissima Miq mesocarp has a low potency in HMG-CoA reductase inhibitory activities.

Introduction: Angiotensin-converting enzyme inhibitors (ACEi) are drugs that can control hypertension. Pereskia saccharose Griseb. leaves have been used traditionally as antihypertensive. Objective: The objective of this study was to determine the antihypertensive activity through inhibition of ACE activity, the total phenolic content and total flavonoid content of the ethanolic extract of Pereskia saccharose Griseb. leaves and its fractions. Methods: Extraction was done by maceration with 80\% ethanol and fractionation performed by liquid-liquid partition. Results: In vitro ACE inhibitory activity assay of the ethanolic extract using ACE Kit-WST Dojindo had IC50 value of 3.448 \μg/mL and ethyl acetate fraction had IC50 value of 1.714 x 10-3 \μg/mL. Ethyl acetate contained the highest amounts of both TPC (72.991 \± 0.932 mg GAE/g sample) and TFC (61.337 \± 1.612 mg QE/g sample). Conclusion: The results suggest that Pereskia saccharose Griseb. possess ACE inhibitory activity.

Introduction: Garcinia has been known as a rich source of xanthones, flavonoids, and phenols. The aim of this research is to obtain data of antioxidant activity and to observe potential inhibition of lipoxygenase activity that most active from methanolic, ethyl acetate and n-hexane extracts with total flavonoids content from most active extracts from the bark of Garcinia hombroniana Pierre. Methods: The antioxidant activity was measured using the ferric reducing antioxidant power (FRAP), the anti-inflammatory assay was measured using inhibition of lipoxygenase activity test, qualitative analysis of flavonoids using thin layer chromatography, and total flavonoids content was measured using AlCl3 colorimetric method. Results: The results showed that the ethyl acetate extract from G. hombroniana Pierre stem bark as the most active extract for antioxidant and lipoxygenase inhibition activity with EC50 and IC50 value consecutively 15.34 \μg /ml; 0.26 \μg /ml. Total flavonoids content of ethyl acetate is 7.430 mg QE/g extract. The results of this study showed bark extract Garcinia hombroniana Pierre has antioxidant activity and potent to inhibit lipoxygenase activity. Conclusion: Based on the research for methanolic, ethyl acetate and n-hexane extract, it can be concluded that the ethyl acetate extract of G. hombroniana Pierre as the most active extract for antioxidant and lipoxygenase inhibition activity.

Introduction: Antioxidant is one of the therapeutic strategies to overcome oxidative stress and inhibit synthesis of inflammatory mediators through lipoxygenase pathway. Garcinia is the largest of Clusiaceae family which has been proven to provide antioxidant and anti-inflammatory activity. Garcinia kydia Roxburgh is one of the plants of this genus which is known to have antioxidant activity but lipoxygenase inhibition activity from this plant was unknown. Methods: This study aimed to test antioxidant activity of the methanol, ethyl acetate and n-hexane extract from Garcinia kydia Roxburgh leaves by FRAP (Ferric Reducing Antioxidant Power) method, anti-inflammatory activity was tested by inhibiting lipoxygenase and total flavonoid content by colorimetric methods AlCl3. Results: The results showed an antioxidant activity of methanol extract, ethyl acetate and n-hexane leaves of Garcinia kydia Roxburgh have EC50 value, respectively 18,448; 12,389 and 31,260 \μg/mL, and the lipoxygenase inhibition activity have IC50 value, respectively 0,556; 0,212 and 3,575 \μg/mL. Ethyl acetate extract of Garcinia kydia Roxburgh leaves was the most active extract in this study which has total flavonoid content, 30,650 mgQE/ gram extract. Conclusion: The conclusion, Garcinia kydia Roxburgh has antioxidant and lipoxygenase inhibition activity, with ethyl acetate extract as the most active extract which contains total flavonoids.
