NMR-based metabolic profiling and antioxidant activity of ethanol extract.

The metabolite profile of the ethanol extract from was assessed using the 1D NMR approach amalgamated with 2D NMR. an indigenous plant found in Indonesia, possesses considerable promise as a raw material for medicinal products. We examined the antioxidant capacity of the extract using DPPH and ABTS methods.

Characteristics of Indonesian Stingless Bee Propolis and Study of Metabolomic Properties Based on Region and Species.

The chemical compounds found in propolis vary according to plant sources, species, and geographical regions. To date, Indonesian propolis has not yet become standardized in terms of its chemical constituents. Thus, this study aimed to identify the presence of marker compounds and determine whether different classes of Indonesian propolis exist.

Rupture of sinus of Valsalva in a young laborer: A rare case report.

Ruptured sinus of Valsalva (RSOV) upon physical exertion is rare but should be considered in differential in young adults. Symptoms of acute heart failure, hemodynamic instability, and continuous heart murmur raises suspicion for RSOV and requires emergent surgical repair of right ventricular outflow tract.

Ultrasonic-Assisted Extraction of Xanthorrhizol from Roxb. Rhizomes by Natural Deep Eutectic Solvents: Optimization, Antioxidant Activity, and Toxicity Profiles.

Xanthorrhizol, an important marker of , has been recognized for its different pharmacological activities. A green strategy for selective xanthorrhizol extraction is required. Herein, natural deep eutectic solvents (NADESs) based on glucose and organic acids (lactic acid, malic acid, and citric acid) were screened for the extraction of xanthorrhizol from .

The neuroprotective potential of turmeric rhizome and bitter melon on aspartame-induced spatial memory impairment in rats.

Aspartame is widely used artificial sweetener. However, chronic exposure to aspartame led to spatial memory impairment and elevated oxidative stress in the brain. Extract of turmeric rhizome () (TUR) and extract of bitter melon () (BM) is known to have antioxidant activity.
