Comparative metabolomics analysis of pericarp from four varieties of Zanthoxylum bungeanum Maxim

Quality analysis of Idesia polycarpa fruit oil samples from cultivars with different phenotypes

To study the quality characteristics of Idesia polycarpa fruit oil (IPFO) samples under varying phenotypic traits and their differences, three typical phenotypic fruits of the same cultivar were compared, both morphologically and chemically. The results revealed that the highest water content (51.90 %) occurred in small red fruits (RID-S), and the highest oil content (20.63 %) was obtained in large yellow fruits (YID). A total of 532 aroma compounds were identified via gas chromatography-mass spectrometry (GC-MS), with terpenes as the major contributors. The fatty acid composition was dominated by linoleic acid (LA), palmitic acid and oleic acid, and the LA content was highest in large red fruits (RID-B) (1633.25-1807.21 μg/mL), whereas the palmitic acid and oleic acid contents were highest in YID (863.72-976.70 μg/mL and 505.96-604.04 μg/mL, respectively). The oil quality of I. polycarpa varied according to its phenotypic characteristics, with RID-B identified as an excellent cultivar, followed by YID and RID-S.

Comprehensive Analysis of 11 Species of Euodia (Rutaceae) by Untargeted LC-IT-TOF/MS Metabolomics and In Vitro Functional Methods

The Euodia genus comprises numerous untapped medicinal plants that warrant thorough evaluation for their potential as valuable natural sources of herbal medicine or food flavorings. In this study, untargeted metabolomics and in vitro functional methods were employed to analyze fruit extracts from 11 significant species of the Euodia genus. An investigation of the distribution of metabolites (quinolone and indole quinazoline alkaloids) in these species indicated that E. rutaecarpa (Euodia rutaecarpa) was the most widely distributed species, followed by E. compacta (Euodia compacta), E. glabrifolia (Euodia glabrifolia), E. austrosinensis (Euodia austrosinensis), and E. fargesii (Euodia fargesii). There have been reports on the close correlation between indole quinazoline alkaloids and their anti-tumor activity, especially in E. rutaecarpa fruits which exhibit effectiveness against various types of cancer, such as SGC-7901, Hela, A549, and other cancer cell lines. Additionally, the E. rutaecarpa plant contains indole quinazoline alkaloids, which possess remarkable antibacterial properties. Our results offer novel insights into the utilization of Euodia resources in the pharmaceutical industry.
