Background: Eleutherine bulbosa (Mill.) Urb., known as Bawang Dayak, is commonly found growing in Kalimantan, Indonesia. The characteristics of the environment in which the plant grows greatly influence the characteristics of the plant and its biological activity. Objective: This study aimed to determine the pharmacognostic profile and evaluate the antidiabetic activity of E. bulbosa bulb extract obtained from Kota Bangun, Kutai Kertanegara, Indonesia. Methods: The dried powdered of E. bulbosa bulbs was extracted using two different methods (maceration and microwave-assisted extraction). The evaluation of the sample fluorescence and non-specific parameters was done. The antidiabetic activity of the extracts was conducted using streptozocin-induced mice and histopathology analysis. Results: The fluorescence evaluation indicated various secondary metabolites contained in E. bulbosa simplicia. Non-specific parameters include drying loss (8.83{\textpm}0.2611\%), water content in simplicia (8.04{\textpm}0.7481\%), specific gravity (1.04{\textpm}0.0058\%), total ash content (20.3{\textpm}0.1583\%), acid insoluble ash content (1.70{\textpm}0.0608\%), ethanol content in extract (0.99{\textpm}0.0017\%), lead content (0.010 mg/g), cadmium (0.091 mg/g), Arsenic (0.0003 mg/g), aflatoxin (not detected), and mold/yeast (0.8 {\texttimes} 105 colonies/g) meet the established regulations. Meanwhile, the antidiabetic assay showed that both extracts decreased the blood glucose levels in mice during the 14 days of treatments in a dose-dependent manner. This activity is correlated with the increased repair of pancreatic beta cells as observed by histopathological analysis. Conclusion: The dried bulbs of E. bulbosa obtained from Kota Bangun, Kutai Kertanegara, East Kalimantan, Indonesia meet the standards set as raw materials for antidiabetic herbal medicines.

Background and Objectives: Dengue viruses (DENV) is a mosquito-borne members of the Flaviridae family.To date, more than 2.5 billion people in over 100 countries are at risk of infection, and approximately 20 million infections were reported annually. Currently, There is no specific antiviral treatment available for DENV infection. Natural products possess a wide range of biological and biochemical potential. Among them, plants are one of the most important sources for discovering new drugs for therapy. Our previous study, showed that Cassia alata has potency as antiviral to DENV, however drug of action still unclear. Materials and Methods: We explore the drug of action of C. alata leaves exract and its fraction through time of addition studies and effect of solvents wtih the dose based on the previous study. Results: The most effective inhibition druf of action was determined by focus assay. Meanwhile the toxicity was measured by MTT assay. These studies demosntrated that ethanol extract of Cassia alata 1 mg/ml showed strong inhibition in both early step (receptor and attachment to host cells) and post infection with inhibition 96.04 \% and 99.16 \%.Compared with those fractions, Cassia alata ethanol extract has strongest inhibition DENV in every step of virus replication. Conclussion: Cassia alata ethanol extract has strongest inhibition DENV in every step of virus replication with the average of inhibition more than 95 \%. Ethyl acetate and hexane has strongest inihibition with the average of inhibition 100 \%.
