Treatment Of Diabetes

This study aims to find the treatment of diabetes using natural materials by exploring plants in the province of East Nusa Tenggara. his research was conducted out by extracting the Strychnos nitida G.Don stem using a method of maceration by ethanol 70%. Ethanol extract was then fractionated using n-hexane and ethyl acetate. Simplicia from maceration and fractionation results were then tested for antioxidant activity, α-glucosidase inhibition activity and identification of active compounds. The results showed that ethyl acetate fraction had the lowest IC50 value of 86.83 μg / ml. Results of the α-glucosidase activity test showed that ethyl acetate fraction and n-heksan fraction at 900 ppm had the highest percentage of inhibition of 34.23% and 33.89%. Identification using LCMS/MS method showed that ethyl acetate fraction consist of Benzenemethamine, N, N-dioctyl- as an antioxidantcompound and compound 24-methyl-5-cholestone-hexol as an antidiabetic compound. From the results of this study, we concluded that the extract of kayu ular Strychnos nitida G.Don stem has inhibition activity toward α-glucosidase enzyme.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are the treatment options for relieving pain. However, long-term use can trigger gastrointestinal bleeding. Therefore, alternative analgesics which have the same therapeutic effect with lower side effects are needed. Limau (Citrus amblycarpa) is an empirical drug for tingling and cramping. The aim of the study is to determine the analgesic activity of ethanol extract of C. amblycarpa fruit peel. The method used in testing analgesic activity is the Hot Plate method. The study was conducted by dividing 30 mice into 6 groups. The group given CMC-Na 1% was used as a negative control, the group given suspension of sodium diclofenac dose of 6.5 mg/kg of body weight was used as a positive control, and the group given suspension of ethanol extract of C. amblycarpa fruit peel with dose variations 100, 300 and 600 mg/kg of body weight. The test animals were placed on top of the Hot Plate with a temperature of 70°C at 30 minutes after giving suspension test and the response time of mice to heat was observed every 30 minutes for 3 hours with cut off time 15 second. Based on the test results, it can be concluded that the administration of ethanol extract of C. amblycarpa fruit peel with 100, 300 and 600 mg/kg of body weight gave analgesic activity on mice compared to the negative controls (CMC-Na 1%).   Keywords: C. amblycarpa, Fruit Peel, Analgesics, Hot Plate

Tetrapleura Tetraptera

The use of antioxidants has emerged as a promising therapeutic strategy for the management of mitochondrial dysfunction and other oxidative stress-related degenerative pathologies. Tetrapleura tetraptera is a well-known tree and its fruit is applied traditionally as spice and in the preparation of remedies for different ailments. In this study, the gas chromatography-mass spectrometry (GC-MS) analysis and mitochondrial functionality potential of T. tetraptera fruits were investigated. GC-MS was used to detect compounds in then-hexane and ethanol extracts of T. tetraptera fruits. Cupric reducing antioxidant capacity (CUPRAC) assay was used to evaluate the mitochondrial functionality potential of the ethanol extract. GC-MS analysis revealed the presence of six compounds in then-hexane extract of T. tetraptera fruits. These compounds were detected in trace quantities, the most abundant being 2,3-dimethyl-3-buten-2-ol (0.04%). The compounds: cis-vaccenic acid (35.37%), n-hexadecanoic acid (28.09%), 6-octadecenoic acid (25.21%), and octadecanoic acid (11.33%) were identified in the ethanol extract of the fruits. Consequently, the ethanol extract was subjected to CUPRAC assay. The ethanol extract exhibited a concentration-dependent high cupric reducing capacity, returning CUPRAC values in the range of 0.090 to 0.403 at the concentration of 10 – 80 μg/ml. This activity was comparable to that of the positive control, naringenin, which showed CUPRAC values of 0.059 – 0.378 at the same concentrations. These results indicate that T. tetraptera fruits possess good antioxidant property as evaluated by other related antioxidant assays. This could be attributed to a synergistic effect of the phytochemical constituents. Hence consumption of T. tetraptera fruits could be beneficial for the prevention of mitochondrial dysfunction and other oxidative stress-related degenerative disorders.
