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: In North Sumatra, Castanopsis costata is commonly used by traditional practitioners for the treatment of diabetes mellitus, however, no studies have been carried out to substantiate this practice. Therefore, this study aims to evaluate the anti-diabetic activity of extract and fractions of C. costata leaves in mice with alloxan-induced diabetes. Methods: Swiss albino mice with alloxan-induced diabetes, were acquired and subjected to the experimental evaluations. Subsequently, the fasting blood glucose levels of the diabetic mice groups treated with glibenclamid, extract and fractions, as well as the untreated group, were evaluated after two weeks of therapy. Results: Based on the results, the ethanolic extract of C. costata considerably reduced the mice{\textquoteright}s blood glucose levels in a dose-dependent manner, at dosages of 25, 50, 100, and 200 mg/kgBW (\% DBGL: 21.10\%, 46.36\%, 58.94\%, and 60.93\%, respectively). In addition, the water fraction of C. costata leaves produced a greater reduction in blood glucose levels (\% DBGL: 78.93\%), compared to the ethyl acetate and n-hexane fractions (\% DBGL: 67.06\% and 58.83\%), respectively. Meanwhile, treatment with the antidiabetic drug, glibenclamide (5 mg/kgBW) produced a 50.75\% reduction in blood glucose levels. Conclusion: Based on the findings, the extract and fractions of C. costata leaves were concluded to exhibit significant anti-diabetic activity. This supported the claim that traditional practitioners in North Sumatra use the plant extract for diabetes treatment.

Background: The red dragon fruit peel, which is rarely used in general, contains higher antioxidant properties compared to the flesh parts and has various secondary metabolites utilised in medicines. Objectives: This study was aimed to determine the effects of ethanol extract administration of the red dragon fruit peel (Hylocereus polyrhizus) against the decline of blood glucose levels in diabetes mellitus rats. Methods: In this study, the total of 24 male white Wistar rats (Rattus novergicus) were divided into 4 groups. All experimental animals were induced to diabetic conditions by the administration of streptozotocin and nicotinamide dosages at 45 mg/kg body weight and 110 mg/kg body weight, respectively. For 14 days, each group was treated accordingly. The first group or negative control (NC) was treated with the administration of CMC-Na 0.5\% dose 2 ml/200 g body weight; the second group or positive control (PC) was administrated with glibenclamide dose 0.09 mg/200 g body weight; the third (E1) and fourth (E2) groups were administered with the ethanol extracts of the red dragon fruit peels at dosages of 37.44 mg/200 g body weight and 74.88 mg/200 g body weight, respectively. Results: After the 14-day trial, the average levels of blood glucose on the negative control group (382.92 mg/dl) experienced no decline, and the blood glucose levels amongst groups were statistically different (p\<0.05). Conclusion: The anti-diabetic activity of the red dragon fruit peel in the ethanol extract dose 74.88 mg/200 g body weight is statistically equal to the glibenclamide dose 0.09 mg/200 g body weight.

Background: The Chenopodium album L. commonly recognized as Bathua, is widely distributed globally and contains various phytoconstituents that help treat several diseases. However, until now, aerial parts{\textquoteright} antidiabetic potential and the plant{\textquoteright}s acute toxicity at fraction level have never been established. Objectives: To investigate the acute toxicity, the in-vitro, in-vivo antidiabetic potential of the plant at fraction level. Materials and Methods: The aerial parts of the plant were fractionated into different fractions, i.e., flavonoid fraction (CAFF), tannin fraction (CATF), alkaloid fraction (CAAF), saponin fraction (CASF), and were analyzed for in-vitro alpha-amylase inhibition assay. The CAFF, CATF, and CAAF were selected based on in-vitro alpha-amylase inhibition assay results and were further screened for its acute toxicity and in vivo antidiabetic activity using a high-fat diet and streptozotocin-induced diabetes model. The CAFF was characterized by LC-MS, and a molecular docking study was carried out. Results: The in-vitro alpha-amylase inhibition assay revealed that CAFF was found to be more potent than standard Acarbose having IC50 values 122.18 {\textpm} 1.15 and 812.83{\textpm} 1.07 μg/ml, respectively. The CAFF fraction was found to possess potent antidiabetic activity in a dose-dependent manner in both in vitro and in vivo diabetic models and did not produce any sign of severe toxicity. Furthermore, the bioactive CAFF fraction was characterized by LC-MS, showed the presence of quercetin 3-O-(2{\textquoteright}{\textquoteright},6{\textquoteright}{\textquoteright}-di-O-rhamnosyl) glucoside (QRG) or quercetin 3-O-(2{\textquoteright}{\textquoteright},6{\textquoteright}{\textquoteright}-di-Orhamnosyl) galactoside (QRGa) and quercetin 3-O-rutinoside (rutin) (QR). It is predicted from the molecular docking study that the CAFF fraction primarily acts as an alphaamylase inhibitor. Conclusion: The CAFF fraction was found to poses dose-dependent potent antidiabetic activity and did not produce any sign of severe toxicity and primarily act as an alpha-amylase inhibitor.

Introduction: Kalanchoe pinnata (Lam) Pers (Crasulaceae) is a succulent ornamental plant. In Costa Rica, the leaves are used as a coadjuvant treatment for Diabetes Mellitus based on traditional knowledge of natural remedies. Moreover, there are some studies mentioning its use for Diabetes Mellitus as medicinal plant in several countries. This research aimed to demonstrate the antidiabetic properties of hydroalcoholic extracts of K. pinnata leaves through phytochemical screening, alpha amylase inhibition and rodent models. Methods: Crude extracts of K. pinnata leaves were prepared by infusion and decoction using water:ethanol (70:30) as a solvent. The extracts prepared by decoction (LAED, lyophilized-water:ethanoldecoction) and by infusion (LAEI, lyophilized-water:ethanol-infusion) were analyzed by FolinCiocalteu, HPLC and capacity of inhibition of α-amylase activity. To determine hypoglycemic activity in rats, extracts were administered orally at doses of 250, 500 and 750 mg/Kg and blood sugar levels were monitored over a four hours period using a glucometer. Results: A significant reduction (p \< 0.05) in blood glucose was observed after one hour in rats treated with 500 mg/Kg of LAED extract. Treatment with 750 mg/Kg LAEI induced a statistically significant reduction in blood sugar at 90, 180 and 240 min, showing that the glucose-lowering effect of this extract was greater at a higher concentration. Conclusions: This study confirmed the hypoglycemic effect of K. pinnata extracts in the acute phase in rats and supports the use of this Crassulaceae as a home remedy.
