Abstract

Abroma augusta is a bush plant that lives on the edge of the river. This plant is commonly used as an anti-inflammatory drug for joints and broken bones. It contains several secondary metabolites, such as alkaloids, triterpenoids, steroids, and flavonoids, which exhibit anti-inflammatory activity. UV-visible (UV-Vis) spectrophotometry of isolate 1.3 indicated absorption at a maximum wavelength of 282 nm. The wavelength suggested that the electron transition π–π* is the absorption of UV spectra typical for triterpenoid compounds that have chromophores in the form of non-conjugated double bonds. FT-IR spectrophotometer characterization data from isolate 1.3 revealed the presence of triterpenoid compounds having carboxyl groups C-O (ester), C-(CH3)2 (gem-dimethyl), carbonyl C = O esters, and C-H (alkyl). Analyses of UV-Vis, FT-IR, GC-MS, 1H-NMR, and 13C-NMR spectra showed that the compound obtained was the triterpenoid β-amyrin. Activity test demonstrated that isolate 1.3 with a 10 mg dose showed stronger anti-inflammatory activity than the positive control of sodium diclofenac.

Abstract

Diabetes is a common and rapidly spreading disease that affects 6.6% of the world’s population. Metformin hydrochloride (HCl) is an effective oral pharmacological treatment for type 2 diabetes mellitus (T2DM) patients because of its capability to reduce glucose levels and the risk of hypoglycaemia. However, gastrointestinal sensitivities to this drug can cause diarrhoea, nausea, vomiting and stomach ache. An alternative is controlled release technology by coating metformin with carboxymethyl cellulose (CMC) and zinc-metal-organic framework (Zn-MOF) through the encapsulation method. Therefore, this study aimed to coat metformin formulations using CMC in a Zn-MOF to control release into the body and minimise the side effects related to doses. The results showed that CMC/metformin@Zn-MOF encapsulation had a controlled blood sugar lowering effect and stable healing effectiveness even at a low concentration of 1:10 of local metformin. In vitro, the released concentrations from local metformin tablets and CMC/Metformin@Zn-MOF were 199.50 ppm of 500 ppm and 42.182 ppm of 50 ppm, with release percentages of 39.90% and 84.364%, respectively. This study found that metformin masking using CMC and Zn-MOF maximally produced a modified release formula along the intestine by reducing the concentration to increase tolerability in lowering blood sugar effectively for T2DM patients with minimal side effects.
