Background: Propolis has been widely reported as having various biological activities. However, Indonesian propolis seems to be less explored. Objective: The present study aimed to analyze the antihypertensive activity of Indonesian propolis in rats. Materials and Methods: Hypertension was induced by high-NaCl (8\%) diet for 3 weeks. A total of 36 rats were divided into 6 groups, including standard diet group (SD), high-NaCl diet group (NaD), high-NaCl diet group + captopril (25 mg/ kg) (PD), high-NaCl diet + propolis from Riau Archipelago (NaDP1), high-NaCl diet + propolis from Lampung (NaDP2) and high-NaCl diet + propolis from South Sulawesi (NaDP3). Propolis was daily administered at dose of 200 mg/ kg on hypertensive rats for 1 week. Blood pressure and body weight were weekly measured. Moreover, routine urine analysis, haematological parameters and lipid profiles at week 4 were determined. Results: The results showed that high-NaCl diet successfully induced hypertension in rats after 3 weeks of intervention. However, the diet did not cause weight gain (p\>0.05). All Indonesian propolis samples significantly reversed either systolic or diastolic blood pressure of hypertensive rats. From urine analysis, propolis from Riau Archipelago and Lampung showed diuretic effect. The haematological analysis mainly showed no significant difference compared standard diet group. Furthermore, LDL and HDL concentrations were significantly improved by propolis from Lampung and South Sulawesi, respectively (p\<0.05). In addition, we only found significant decrease in relative weight of liver in all groups administered with high-NaCl diet (p\<0.05). Conclusion: The present study suggests that all Indonesian propolis possessed antihypertensive activity.

Introduction: Propolis is a resinous substance collected by bees to protect their hives. One of the least explored function of propolis is its antiemetic activity. The present study aimed to investigate the antiemetic activity of Trigona spp. propolis from three provinces of Indonesia. Methods: Ultrasound-assisted extraction using two kinds of solvent, water and ethanol was conducted to extract propolis from South Sulawesi, South Kalimantan and Banten. Antiemetic activity was observed on copper sulfate\–induced emesis in young chicks. Result: All propolis indicated antiemetic activity, in which water extract had higher activity than ethanol extract. Regardless the type of solvents, propolis from South Sulawesi showed higher antiemetic activity than others. Conclusion: This study demonstrated that propolis has antiemetic activity, in which propolis from South Sulawesi showed the highest activity and water extraction is recommended.
