KUMIS KUCING (ORTHOSIPHON STAMINEUS [BENTH.]) LEAVES ETHANOL EXTRACT AS ANTIâ€‘OBESITY AGENT IN HIGHâ€‘FAT DIETâ€‘INDUCED OBESE MICE
Objective: The leaves of kumis kucing (Orthosiphon stamineus [Benth.]) are used as folk medicine for lifestyle-related diseases such as hypertension,
hyperlipidemia, and diabetes mellitus in Southeast Asia countries, especially Indonesia. Obesity is closely associated with lifestyle-related disease.
The objective of this research was to evaluate the effect of kumis kucing leaves ethanol extract in high-fat diet-induced obese mice, and its ability to
inhibit pancreatic lipase enzyme activity in vitro.
Methods: Obese mice groups were fed a high-fat diet for 30 days and treated with kumis kucing leaves ethanol extract for 2 weeks. The measurement
parameter includes body weight, organ weight, and visceral fat mass. Experiments were also carried out to clarify the effect of kumis kucing leaves
ethanol extract inhibited pancreatic lipase enzyme activity in vitro.
Results: Kumis kucing-treated groups showed a significant decrease in body weight, organ weight, and visceral fat mass after 2 weeks treatment
compared with untreated groups. Furthermore, kumis kucing leaves ethanol extract showed potency as the pancreatic lipase activity inhibitor in vitro.
Conclusion: Kumis kucing leaves ethanol extract can inhibit the development of obesity in high-fat diet-induced obese mice. The effect appears
mediated by inhibiting the pancreatic lipase activity. The results from this study suggested that the kumis kucing leaves may have a considerable
impact as potential anti-obesity agents.
