Objective: This research elaborated role of alpha mangostin and xanthone on fasting blood glucose, insulin and langerhans islet in alloxan induced diabetic mice. Methods: Fasting blood glucose, insulin and langerhans islet test were conducted using male Mus musculus mice, divided into 10 groups randomly, which were normal, control (alloxan induced only), glibenclamide, various doses of α-mangostin and xanthone (5, 10, 20 mg/kgbw). Mice were treated for 21 days. Overnight-fasted mice (12 h) were sacrificed by cervical decapitation on day 21st, following the ethical norms granted by the ethics committee. Fasting blood glucose and insulin plasma were checked. Pancreatic tissues were excised from sacrificed animals, and then fixed in 10 \% (v/v) neutral buffered formalin. Histologic observations for Langerhans area were performed after staining using Gomori staining method. Results: The effects of alpha mangostin and xanthone on fasting blood glucose different significantly to control, and were not significantly different from glibenclamide and metformin. Increasing alpha mangostin/xanthone dose from 5 mg/kgbw to 20 mg/bw also did not cause significant differences, although the best results were obtained at a dose of 20 mg/kgbw. Insulin plasma analize showed that there were no significant difference between alpha mangostin/xanthone to normal group, except xanthone 10 mg/kgbw. Langerhans area showed significant difference between alpha mangostin/xanthone to control group. But there{\textquoteright}s still had significant difference if we compare to glibenclamid/metformin group. Conclusion: Alpha mangostin and xanthone are two substances that showed antidiabetic effect on fasting blood glucose level, insulin plasma and Langerhans islet.

Introduction: Sleep disorder may have detrimental consequences on health and one of the treatments is the use of hypnotics. Unfortunately, hypnotics treatment may also be accompanied by side effects and lead to dependence. The present study aimed to investigate the sleep improving effects of ethanol extract of Gardenia augusta (L.) Merr. flowers in rat model. Methods: Rats were assigned into group receiving the extract (at 0.9 or 1.8 g/kg), the reference drug crocetin (at 0.9 mg/kg) or vehicle, once a day orally for 15 days. Results: Tested on day 1 and 14 of treatment, the rats receiving 1.8 g/kg of the extract showed improvements in sleep latency, sleep duration, sleep efficiency, wake episodes, and sleep cycle, which were significantly different from crocetin. Furthermore, tested on day 2 and 15 of treatment, the rats treated with 1.8 g/kg extract demonstrated superior sedative rating scale compared to crocetin. Conclusions: Results of the present study indicates the potential of Gardenia augusta (L.) Merr. flower extract to be used as an adjunct treatment for sleep disorder.
