“…The metabolites with the highest abundances in aromatic rice were 2-hexenal, 2-isopropyl-5-methyl-9-methylenebicyclo[4.4.0]dec-1-ene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and 5-ethyl-2-decen-4-one. Hexenal was considered as a marker compound to distinguish aromatic rice from non-aromatic rice varieties [ 3 , 30 ]. In this study, the content of 2-hexenal in three aromatic rice were much greater than the content of 2-hexenal in the non-aromatic rice varieties, moreover the 2-hexenal content of Daohuaxiang 2 was 38 times higher than the 2-hexenal contents of non-aromatic rice varieties ( Table 3 ).…”

Non-aromatic rice is often sold at the price of aromatic rice to increase profits, seriously impairing consumer experience and brand credibility. The assessment of rice varieties origins in terms of their aroma traits is of great interest to protect consumers from fraud. To address this issue, the study identified differentially abundant metabolites between non-aromatic rice varieties and each of the three most popular aromatic rice varieties in the market using an untargeted metabolomics approach. The 656 metabolites of five rice grain varieties were determined by headspace solid-phase extraction gas chromatography-mass spectrometry, and the multivariate analyses were used to identify differences in metabolites among rice varieties. The metabolites most differentially abundant between Daohuaxiang 2 and non-aromatic rice included 2-acetyl-1-pyrroline and acetoin; the metabolites most differentially abundant between Meixiangzhan 2 and non-aromatic rice included acetoin and 2-methyloctylbenzene,; and the metabolites most differentially abundant between Yexiangyoulisi and non-aromatic rice included bicyclo[4.4.0]dec,1-ene-2-isopropyl-5-methyl-9-methylene and 2-methylfuran. Overall, acetoin was the metabolite that was most differentially abundant between the aromatic and non-aromatic rice. This study provides direct evidence of the outstanding advantages of aromatic rice and acts a reference for future rice authentication processes in the marketplace.

“…GC-MS is the most commonly used method for the analysis of essential oils components at present [27,28]. The yellow PEO with characteristic odor was obtained by hydrodistillation and 41 components were identified by GC-MS, accounting 95.73% of the total oil (Table 1), and the main components were respectively α-Pinene (40.91%), Limonene (24.82%), and β-Pinene (7.04%).…”

Pinecone is a traditional folk herb, which has been used in China for many years. In this paper, the essential oil from Pinus koraiensis pinecones (PEO) was obtained by hydrodistillation and 41 compounds were identified by gas chromatography–mass spectrometry (GC-MS), mainly including α-Pinene (40.91%), Limonene (24.82%), and β-Pinene (7.04%). The purpose of this study was to investigate the anti-tumor activity of PEO on MGC-803 cells and its mechanism. Anti-tumor experiments in vitro showed PEO could significantly inhibit the proliferation and migration of MGC-803 cells, and it also could arrest the cell cycle in the G2/M phase, decrease the mitochondrial membrane potential, and induce apoptosis. Finally, the effects of PEO on genes expression on MGC-803 cells were analyzed by RNA sequencing, and results showed that after treatment with PEO, 100 genes were up-regulated, and 57 genes were down-regulated. According to the KEGG pathway and GSEA, FAT4, STK3, LATS2, YAP1, and AJUBA were down-regulated, which were related to HIPPO signaling pathway. Real-time PCR and western blot further confirmed the results of RNA sequencing. These results indicated that PEO may exert anti-tumor activity via the HIPPO/YAP signaling pathway. The anti-tumor mechanism of this oil can be further studied, which is important for the development of anti-tumor drugs.

“…Essential oil extracted from plants is extensively used in the cosmetic, pharmaceutical and food industries [1,2] . Due to their anti‐inflammatory, antibacterial, antiviral and anticancer potential, studies investigating volatile compounds found in essential oils have increased [3–6] . Pyrrosia mirbel (Polypodiaceae) fronds are generally used to treat urethritis, nephritis and trauma hemorrhages [7] .…”

The continued development of folk medicine to potentially treat infectious diseases has resulted in an increase in natural sources of antimicrobial agents, particularly the use of plant essential oils containing volatile products from secondary metabolism. The objectives of this investigation were to (i) analyze the chemical components of essential oils using GC/MS and (ii) to examine their in vitro antimicrobial activities against four strains of bacteria (Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Shigella flexneri) and one fungus (Candida albicans) by determining minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) in liquid and solid media, respectively, from different Pyrrosia petiolosa locations. Eightyeight evaporable compounds were confirmed in their essential oils; the major components in the oils were 2,4pentadienal (12.5 %), phytol (10.5 %) and nonanal (8.6 %). Based on hierarchical cluster analysis, Pyrrosia samples were categorized into four groups, indicating significant essential oil diversity from different Pyrrosia locations. Results also indicated that essential oils had a broad spectrum of antibacterial activities, particularly against Shigella flexneri and Staphylococcus aureus with MICs of 5 μL/mL. Results from this investigation are the first to record the chemical component and antimicrobial potential of essential oils from different P. Petiolosa locations.
