SOYBEAN SELECTION AGAINST CERCOSPORA LEAF BLIGHT DISEASE CAUSED BY CERCOSPORA KIKUCHII BASED ON ANATOMICAL RESISTANCE
Soybean (Glycine max L. Merr.) is the third food crop commodity after rice and maize in Indonesia. This plant is also known as the most important source of vegetable protein, which is relatively inexpensive, but a decrease in soybean productivity can occur due to infection with disease-causing pathogens, one of is Cercospora kikuchii which causes Cercospora leaf blight (CLB). The research objectives were to determine the anatomical resistance and disease severity of soybean cultivars against CLB. The method was an experiment with a completely randomized design (CRD) factorial pattern; factor 1 being soybean cultivars (Dering, Slamet, Grobogan, Wilis) and factor 2, namely pathogen inoculation (0 conidiospores/mL and 105 conidiospores/mL). Anatomical method preparations using paraffin, staining with 1% safranin. Disease criteria are based on the council of scientific and industrial research (CSIR) assessment method. Data were analysis used analysis of variance (p<0.05)

Coprinus comatus (O.F. Mull.) Pers. is a medicinal and edible mushroom containing bioactive compounds known as antidiabetic and antioxidant agents. The pancreatic β-cells were sensitive to reactive oxygen species (ROS) attacks, which can cause necrosis and disrupt insulin production. Therefore, this research aimed to evaluate the C. comatus ethyl acetate extract for antidiabetic and antioxidant to decrease fasting blood glucose, dipeptidyl peptidase-4 enzyme (DPP-4) levels, and increase glutathione peroxidase (GPx). Subsequently, 24 male Wistar rats were divided into six groups, namely 2-5 streptozotocin (STZ)-induced 45 mg/kg, 1/HC (without any treatment), 2/NC (negative control), 3/PC (administered metformin 45 mg/kg Body weight (BW), 4-6 (T1: administered 250 mg, T2: administered 500 mg, and T3: administered 750 mg/kg BW extract). The parameters were analyzed using ANOVA, followed by Duncan’s multiple range test. According to the results, the extract significantly decreased DPP-4 levels, blood glucose and increased GPx (p ≤ 0.05). The 500 mg extract effectively reduced blood glucose levels and DPP-4 enzyme as well as increased levels of GPx.

Data were analysis used analysis of variance (p0.05) and the least significance difference (LSD). The results showed that Dering and Slamet cultivars had the largest cuticle, epidermis, and palisade ratios and the smallest stomata length and width with the largest number of stomata and trichomes compared to Grobogan and Wilis. The disease severity (DS) of the cultivars Dering 14.6%, Slamet 24.64%, Grobogan 24.80% (classified as a resistant with low infection), while Wilis cultivar was 31.08% as a moderately susceptible cultivar with moderate infection. The novelty of soybean cultivar selection against CLB is important and its effectiveness for increasing soybean productivity. Dering, Slamet and Grobogan are likely to be further developed with their resistance to CLB disease.

Coprinus comatus, well-known as Shaggy Ink Cap mushroom, is potential herbal medicine. Synthetic medicines sometimes cause side effects; therefore, it is necessary to innovate with herbal medications with minimal side effects. The study evaluated in vitro and in vivo treatments to evaluate the antioxidant effect and activity of C. comatus. The in vivo treatment was conducted using six groups of Wistar rats (n = 24). Group 1 healthy control (HC), groups 2–6 received 45 mg/Kg BW of streptozotocin once, group 2 just streptozotocin-induced (NC), group 3 was given 45 mg/kg BW of metformin (PC), groups 4–6 were given 250 (T1), 500 (T2), and 750 mg (T3) of C. comatus extract for 14 days, and the in vitro was conducted using an antioxidant oxidant assay. Data were analyzed using analysis of variance and Duncan's multiple range tests. Based on qualitative analysis, C. comatus mycelium extract contained polyphenol, flavonoids, terpenoids, and fruiting body extract had flavonoids, alkaloids, and saponins. The in vitro analysis showed that the mycelium extract had an antioxidant activity by inhibiting free radicals up to 58.51% with an IC50 value of 72.77 mg/L. The in vivo treatment using C. comatus fruiting body extract showed that it could increase the endogenous antioxidant levels of GPx, SOD, catalase and reduce MDA levels (p 0.05). The most effective dose of C. comatus extract is 500 mg. This research has shown the potential of mycelium and C. comatus fruitbody extract as an antioxidant supplement in a diabetic rat model.

Abstract Context Edible mushrooms have a long history of use in traditional Chinese or Japanese medicine. Coprinus comatus (O.F. Müll.) Pers. (Agaricaceae) contains antioxidant and antidiabetic agents. Objective To identify the benefits of ethanol extracts of the C. comatus fruit body in streptozotocin-induced hyperglycaemic rats by evaluating their blood glucose, glycosylated haemoglobin (HbA1c), insulin, glucagon-like peptide-1 (GLP-1), dipeptidyl peptidase-4 (DPP-4), and glutathione (GSH) levels, with and without extract administration. Materials and methods Wistar rats were either left untreated or were administered 45 mg/kg body weight (BW) streptozotocin; 45 mg/kg BW metformin; or 250, 500, or 750 mg/kg BW extract for 14 days. The blood glucose, GLP-1, DPP-4, GSH, insulin, and HbA1c levels were determined. Data were analysed using analysis of variance and Duncan’s multiple range tests. Results Preliminary data showed that administration of C. comatus ethanol extract dose of 250, 500, and 750 mg orally has no toxicity effects after 24 h administration. The ethanolic extract of fruiting body of C. comatus considerably reduced the rat’s fasting blood glucose levels 26.69%, and DPP-4 6.97% at dose of 750 mg. The extract reduced HbA1c 4–4.30%, increased GLP-1 71.09%, GSH 11.19% at dose of 500 mg, and increased insulin levels 13.83%. Extracts contain bioactive compounds such as flavonoid, alkaloid, terpenoids, vitamins C and E, rutin, and saponin. Conclusions The C. comatus extract can be used as herbal medicine that reduces diabetic symptoms. Further investigation on C. comatus extracts should be conducted with gas chromatography-mass spectrometry to characterise the bioactive compounds.

Coprinus comatus is known for its antihyperglycemic benefits. This study aimed to identify the effect of bioactive compounds of C. comatus extract as an antidiabetic agent linked to glucagon-like peptide 1 (GLP-1) and antioxidant properties in increasing glutathione (GSH) levels. This study used six groups of Wistar rats (n = 24). Group 1 comprised the healthy control. Groups 2-6 received 45 mg of streptozotocin/kg body weight (BW) once. Group 3 was also given 45 mg of metformin/kg BW, whereas groups 4-6 were also given 250, 500, and 750 mg of C. comatus ethyl acetate extract/kg BW for 14 days. Antidiabetic effects of alkaloids and saponin were seen in blood glucose and glycated hemoglobin (HbA1c) degradation, increased insulin, and increased inhibition of GLP-1 through dipeptidyl peptidase-4 activity. Flavonoid antioxidants, ascorbic acid (vitamin C), and α-tocopherol (vitamin E) are useful in protecting pancreatic в cells from free radicals. Data were analyzed using analysis of variance and Duncan's multiple range test. C. comatus ethyl acetate extract at doses of 250, 500, and 750 mg/kg BW worked as an antidiabetic and antioxidant agent that contained flavonoids (16.4 mg/L), alkaloids (2.97 mg/L), saponin, rutin (351.13 ppm), vitamin C (132.342 mg/L), and vitamin E (102.320 g/L). The 250-mg dose was effective in increasing insulin (8.11 mlU/mL) and reducing blood glucose (23.92%) and HbA1c (3.775%), whereas the 500-mg dose was effective in increasing levels of GLP-1 (1056.923 ng/L) and GSH (4.62 μmol/L).
