Cardiovascular diseases (CVDs) are a group of disorders of the heart and blood vessels. CVDs are responsible for 37% of deaths in Indonesia. Thrombosis is the main factor causing blood vessel clost in CVDs. Blood vessel clots then affect narrowed blood vessel. This causes strokes. The aim of this study is to determine the antithrombotic effect of water hyacinth ethanolic extract, the effective dose, and the potential to become anticoagulant agent. The water hyacinth was extracted by ethanol 96%. The extract was tested on five groups of mice, each group containing five mice. Each group was tested for fourteen days. Group I and II are fed by extract suspension with varied dose 1 mg/BW and 2 mg/BW. Group III is fed by warfarin as standard. Group IV and V are the positive and negative group, the mice were fed by NaCMC. On the 7th and 14th days, prothrombin time (PT) and activated partial thromboplastin time (aPTT) were conducted. The plasma of group 1-IV mixed with adenosine diphosphate (ADP) as inducer, except plasma of group V used for negative control, did not mixed with ADP. Data analysed by ANOVA and LSD to obtain effective dose. The results showed the difference between PTT and aPTT among the tested groups. Group I and II showed prolonged PT which is 22 and 32 seconds respectively. The control positive showed PT 9.48 seconds on day 7th and 8.22 seconds on day 14th. LSD analysis showed that there is the significant difference between positive control and the other groups. It showed platelet aggregation performed due to the addition of ADP as inducer. There was a significant difference between dose 2 and the negative control group, and there is no significant difference of dose 1. In conclusion, water hyacinth has the antithrombotic activity, the effective dose is 1 mg/BW, and it potential to further developed as anticoagulant agent.   Keywords: antiplatelet, cardiovascular diseases, water hyacinth.

ABSTRACT Background: In diabetes mellitus, hyperglycemia causes oxidative stress that enhances the production of free radicals. The presence of higher levels of malondialdehyde (MDA) indicates the rise of free radicals. On the basis of its role as an antioxidant that binds free radicals and reduces the level of malondialdehyde (MDA). Soursop leaf can act as an antidiabetic agent. This study aimed to examine the efficacy of soursop leaf extract (Annona muricata L.) to decrease the level of MDA level in alloxan-induced diabetic rats (Rattus norvegicus). Subjects and Method: This was an experiment study using pre- and pro-test with control group design. Total of 30 rats were selected for this study and divided into five groups of treatment i.e. group I was given distilled water and standard feed (Negative Control/KI), group II was given vitamin E 150 IU/kgBW/day (Positive Control/KII), group III was given soursop leaf extract 75 mg/kgBW/day (KIII), group IV was given soursop leaf extract 150 mg/kgBW/day (KIV), and group V was given soursop leaf extract 300 mg/kgBW/day (KV). Each group consisted of 5 rats and was given soursop leaf extract for 21 days after being induced by alloxan and high-fat diet. The data were analyzed using Mann-Whitney test. Results: There was a significant difference in KI group compared to KII, KIII, KIV, and KV groups. Soursop leaf extract of 150 mg/kgBW/day was the most effective dose to reduce MDA level in pancreatic rat. Conclusion: Soursop leaf extract of 150 mg/kgBW/day is the most effective dose on pancreatic MDA level reduction.
