[PMID: 37628096 PMCID: PMC10453283 DOI: 10.3390/foods12163097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 08/16/2023] [Accepted: 08/16/2023] [Indexed: 08/27/2023] Open
Abstract
Hexanol is a volatile alcohol and a major component of plant essential oils (EOs). However, the antibacterial activity of hexanol vapor has not been well studied. This study aimed to evaluate the antibacterial activity of hexanol. In this study, seven food-related bacteria were exposed to 1-, 2- or 3-hexanol vapor on agar media to evaluate their growth. Additionally, the total viable counts in three vegetables when exposed to 1-hexanol vapor were measured. The results showed that 1-hexanol exhibited antibacterial effects against Gram-negative bacteria but did not affect Gram-positive bacteria. However, compounds 2- and 3-hexanol did not show antimicrobial activity against any bacteria. For the vegetables, exposure to 1-hexanol vapor decreased the total viable bacterial counts in cabbage and carrot and inhibited bacterial growth in eggplants. In cabbage, 1-hexanol vapor at concentrations over 50 ppm decreased the total viable count within 72 h, and 25 ppm of vapor showed bacteriostatic activity for 168 h. However, 1-hexanol vapor also caused discoloration in cabbage. In summary, 1-hexanol has the potential to act as an antibacterial agent, but further studies are required for practical use. Moreover, the study results may help determine the antimicrobial activity of various EOs in the future.

Sun L, Qi Y, Meng M, Cui K. Comparative Study on the Volatile Organic Compounds and Characteristic Flavor Fingerprints of Five Varieties of Walnut Oil in Northwest China Using Using Headspace Gas Chromatography-Ion Mobility Spectrometry. Molecules 2023; 28:molecules28072949. [PMID: 37049712 PMCID: PMC10096422 DOI: 10.3390/molecules28072949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 03/20/2023] [Accepted: 03/23/2023] [Indexed: 03/29/2023] Open
Abstract
Odor is an important characteristic of walnut oil; walnut oil aromas from different varieties smell differently. In order to compare the differences of volatile flavor characteristics in different varieties of walnut oil, the volatile organic compounds (VOCs) of walnut oil from five different walnut varieties in Northwest China were detected and analyzed using headspace gas chromatography–ion mobility spectrometry (HS–GC–IMS). The results showed that 41 VOCs in total were identified in walnut oil from five different varieties, including 14 aldehydes, 8 alcohols, 4 ketones, and 2 esters. Walnut oil (WO) extracted from the “Zha343” variety was most abundant in VOCs. The relative odor activity value (ROAV) analysis showed that aldehydes were the main aroma substances of walnut oil; specifically, hexanal, pentanal, and heptanal were the most abundant. Fingerprints and heat map analysis indicated that WO extracted from the “Xin2”, “185”, “Xin’guang”, and “Zha343” varieties, but not from the “Xinfeng” variety, had characteristic markers. The relative content differences of eight key VOCs in WO from five varieties can be directly compared by Kruskal–Wallis tests, among which the distribution four substances, hexanal (M), hexanal (D), pentanal (M), (E)-2-hexanal (M), presented extremely significant differences (P<0.01). According to the results of the principal component analysis (PCA), WO extracted from the “Zha343” variety was distinct from the other four varieties; in addition, WO extracted from the “Xin2” variety exhibited similarity to WO extracted from the “185” variety, and WO extracted from the “Xinfeng” variety showed similarity to WO extracted from the “Xin’guang” variety. These results reveal that there are certain differences in the VOCs extracted from five different WO varieties, making it feasible to distinguish different varieties of walnut oil or to rapidly detect walnut oil quality based on its volatile substances profile.

Club 5: 277. 1894., is famous as a worldwide plant with multiple medical parts, including leaves, stems, fruits, etc. Perillae Fructus, the desiccative ripe fruit of P. frutescens, is locally called Zisuzi in Chinese Pharmacopoeia. It is a popularly used herb for relieving cough and asthma, dissipating phlegm and treating constipation in some Asian countries, such as China, Japan, India, South Korea, etc. Various chemical compounds were isolated and identified from Perillae Fructus. THE AIM OF THE REVIEW This review aims to summarize the botany, ethnopharmacological applications, phytochemistry, pharmacology, toxicity and quality control of Perillae Fructus to provide scientific evidence for development and utilization Perillae Fructus. MATERIALS AND METHODS Relevant information about Perillae Fructus was collected from ScienceDirect, PubMed, Web of science, CNKI, WanFang data, ancient classics and clinical reports. Some electronic databases were also retrieved. RESULTS Perillae Fructus was exerted to treat cough and asthma in traditional application. It also had the effect on moistening intestine to relieve constipation for tremendous lipid substances. Up to now, 193 compounds have been isolated and identified from Perillae Fructus, mainly including fatty acids, flavonoids, phenolic acids, phytosterols, triterpenoids and volatile oils. As for its pharmacological activities, prevalent traditional applications of Perillae Fructus have been supported by modern pharmacological experiments in vivo or in vitro, such as anti-inflammatory and anti-oxidant effects. Besides, Perillae Fructus also has hypolipidemic, anti-tumor, antibacterial effects, etc. This review will provide a scientific basis for further studies and rational applications of Perillae Fructus in the future. CONCLUSIONS According to its traditional applications, phytochemicals and pharmacological activities, Perillae Fructus was regarded as a valuable herb for application in medicine and food fields. Although some ingredients have been confirmed to have multiple pharmacological activities, their mechanisms of action are still unclear. Further studies on the material basis and mechanism of action are clearly warranted.

Comprehensive evaluation of chemical composition and health-promoting effects with chemometrics analysis of plant derived edible oils. Food Chem X 2022; 14:100341. [PMID: 35634224 PMCID: PMC9133763 DOI: 10.1016/j.fochx.2022.100341] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 04/14/2022] [Accepted: 05/18/2022] [Indexed: 11/30/2022] Open
Abstract
22 edible oils can be discriminated based on tocopherol and phytosterol contents. In vitro antioxidant activity is correlated to polyphenol, tocopherol, and squalene. Oxidative and heat stress resistance is correlated to tocopherol and phytosterol. In vivo antioxidant activity is correlated to polyphenol, squalene, MUFA and PUFA.
In the last decade, with a growing emphasis on healthy diets, functional edible oils with high nutritional quality are becoming increasingly popular around the world. This study systematically compared the chemical composition and protective effect of 22 vegetable oils using multivariate chemometric tools. The results showed that the fatty acid composition and minor compounds were extremely variable among tested oils. Hierarchical cluster and principal component analysis discriminated these oils according to the tocopherol and phytosterol contents. The Pearson’s correlation analysis indicated that in vitro radical scavenging capacity was significantly correlated to polyphenol, tocopherol, and squalene. Additionally, the ameliorate effects on the heat and oxidative stress, ROS contents, and antioxidant enzyme activities were measured in Caenorhabditis elegans. The results showed that the antioxidant activity and stress resistance were positively correlated to polyphenol, tocopherol, phytosterol, MUFA, and PUFA, respectively. This study may offer an insight into oil discrimination and functional oil exploitation.
