In recent years, natural products with biological activities have been increasingly researched. The elucidation of phytoconstituents is necessary for the development of drugs as a natural alternative for the treatment of various diseases. The work aimed to evaluate in vitro and in silico bioactivities of hexane (CCHE) and methanol (CCME) fractions of ethanolic extract from Centrosema coriaceum Benth (Fabaceae) leaves and elucidate their phytoconstituents. CCHE and CCME showed antifungal activity for Candida glabrata (MIC of 1000 μg/mL) with fungistatic effect and action in cell envelope by sorbitol and ergosterol assays. CCHE and CCME presented promising antioxidant activity against the DPPH radical with IC 50 of 13.61 � 0.50 and 6.31 � 0.40 μg/mL, respectively, and relative antioxidant activity (RAA%) of 45.77 � 3.61/ 28.53 � 2.25 % for CCHE and 82.18 � 2.25/ 51.99 � 3.23 % for CCME when compared to rutin and quercetin, respectively. Moreover, these fractions demonstrated promising results for the inhibition of lipid peroxidation by β-carotene/linoleic acid assay. For antiinflammatory and cytotoxicity activities, CCHE and CCME significantly inhibited the production of nitric oxide and TNF-α, without toxicity on murine intraperitoneal macrophages, respectively. Esters, alkanes, steroids, tocopherols, and terpenes were identified in CCHE by GC/MS. Flavonoids, phenolic acids, and disaccharides were detected in CCME by UFLC-QTOF-MS and FACE. Furthermore, rutin was purified from CCME. In silico predictions evidenced that compounds present in both fractions have high affinity to the fungal membrane besides antioxidant and anti-inflammatory activities. Based on these observations, CCHE and CCME have a noteworthy potential for the design of novel antifungal and anti-inflammatory agents that should be explored in future studies.

Baijiu, a Chinese distilled liquor, plays an essential role in Chinese life and culture. The intricate flavour profile and distinguished quality of baijiu are closely linked to its organic components, which encompass an array of elements such as esters, acids, alcohols, aldehydes, phenols, pyrazines, terpenes, and others. Consequently, the analysis of these components has emerged as a fundamental cornerstone for the study and comprehension of baijiu. In the present review, we succinctly encapsulate the latest research endeavours aimed at the identification and precise quantification of pivotal components within a diverse array of Chinese baijiu exhibiting varying aroma profiles. The culmination of this collective effort has yielded an impressive compendium comprising 397 quantified components, each with meticulously determined concentrations within baijiu. These components are categorised into major, medium, minor, and trace components, based on their respective concentration levels in baijiu. Furthermore, the focal attention on trace components, with concentrations below 1 mg L-1 threshold, is deliberately underscored. This emphasis is ascribed to the pivotal roles of these trace elements in shaping the nuanced flavour and overall quality of baijiu. As a result, the present review not only provides the most comprehensive reference compendium of quantified baijiu components to date, but also furnishes invaluable insights into the multifaceted study of Chinese baijiu.
