Article Abstract
Analyzing bitterness is challenging because of the diverse range of bitter compounds, the variability in sensory perception, and its complex interaction with other tastes. To address this, we developed an untargeted approach to deconvolute the taste and molecular composition of complex plant extracts. We applied our methodology to an ethanolic extract of (Roxb.) H.Karst., a plant recognized for its distinctive bitterness. Chemical characterization was performed through nuclear magnetic resonance spectroscopy experiments together with untargeted liquid chromatography-high resolution tandem mass spectrometry analysis coupled to a charged aerosol detector. After clustering the fractions based on chemical similarity, we performed free sensory analysis and classical descriptive analysis on each cluster. Our results confirmed the attribution of bitterness to iridoids and highlighted the role of other important compounds in the overall taste. This method provides a systematic approach for analyzing and potentially enhancing the taste profiles of plant-based beverages.

A sustainable and energy-efficient method was developed to extract bioactive compounds from black cardamom (Amomum subulatum) using microwave-assisted extraction (MAE) with Natural Deep Eutectic Solvents (NADES). Six NADES composed of choline chloride, lactic acid, citric acid, glucose, and sucrose were prepared by heating and stirring. Lact:Suc and Lact:Gluc, showed the highest extraction efficiencies.

Ethnopharmacological Relevance: Piper sarmentosum (Psar) is widely used in traditional medicine across Vietnam, Thailand, and Malaysia to treat joint pain, inflammation, and digestive ailments. In Vietnam, Psar is commonly used to relieve symptoms associated with gout. Despite its broad ethnomedical applications, the plant has not been comprehensively studied for its anti-gout properties, particularly xanthine oxidase (XO) inhibition.
