Abstract
The present study focused on water-soluble essential oil recovered from the hydrolate of ten Paeonia × suffruticosa cultivars. Thirty-seven components, mostly oxygenated compounds (94.6-99.6%), were detected by gas chromatography-mass spectrometry (GC-MS) and GC-flame ionisation detector (GC-FID). The geranic acid chemotype was discovered (in cultivar 'Lan BaoShi'). Eight key oxygenated components were analysed in silico with antidepressant targets sodium-dependent serotonin transporter (SERT), 5-hydroxytryptamine receptor 1 A (5-HT1A), and monoamine oxidase type A (MAO-A). Geraniol, nerol, citronellol, and geranic acid presented superior docking properties. Phenylethyl alcohol and 1,3,5-trimethoxybenzene were also well docked. These molecules were bound to the active sites successfully (with partial occupancy in SERT). They might increase serotonin level or mimic its effect in central nervous system. (Z)-3-Hexen-1-ol and 1-hexanol showed weak binding. The in silico analysis revealed for the first time that the key water-soluble essential oil components of P. × suffruticosa potentially targeted antidepressant targets.

Antioxidant and Antimicrobial Activity of Plant Hydrosol and Its Potential Application in Cosmeceutical Products. Jundishapur J Nat Pharm Prod 2022.

Abstract
Context: Hydrosol is a residual product from the steam or hydro distillation process of abundant types of plants. It can be separated from the essential oil mixture by the liquid-liquid extraction process. Hydrosols from a variety of plants are becoming increasingly popular in cosmetology, aromatherapy, traditional pharmacy, and food sector; thus, their prospective applications should be further explored. Evidence Acquisition: Hydrosol may generally contain chemicals such as alcohol, ketone, and ester. Based on the previous studies using gas chromatography-mass spectroscopy (GC-MS) analysis, linalool, carvacrol, and α-terpineol are the major chemicals present in plant hydrosol. Results: The chemical composition is either showing antimicrobial or antioxidant properties. The antioxidant properties are important in cosmeceutical products to prevent oxidation of the cosmetic ingredients, while the antimicrobial properties maintain the quality of the cosmetics. Hitherto, hydrosol usage is still unfamiliar in the market, but several cosmetic products have been formulated using hydrosol, such as shampoo, soap, and conditioner. Conclusions: This work will review the hydrosol compound from plants, extraction methods, chemical composition, antioxidant and antimicrobial activities, and the potential of hydrosol in cosmeceutical application.

Chemical Diversity and Potential Target Network of Woody Peony Flower Essential Oil from Eleven Representative Cultivars ( Paeonia × suffruticosa Andr.). MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27092829. [PMID: 35566179 PMCID: PMC9102020 DOI: 10.3390/molecules27092829] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 04/23/2022] [Accepted: 04/27/2022] [Indexed: 12/13/2022]
Abstract
Woody peony (Paeonia × suffruticosa Andr.) has many cultivars with genetic variances. The flower essential oil is valued in cosmetics and fragrances. This study was to investigate the chemical diversity of essential oils of eleven representative cultivars and their potential target network. Hydro-distillation afforded yields of 0.11–0.25%. Essential oils were analyzed by GC-MS and GC-FID which identified 105 compounds. Three clusters emerged from multivariate analysis, representative of phloroglucinol trimethyl ether (‘Caihui’), citronellol (‘Jingyu’, ‘Zhaofen’ and ‘Baiyuan Zhenghui’) and mixed (the rest of the cultivars) chemotypes. ‘Zhaofen’ and ‘Jingyu’ also exhibited low levels of other rose-related compounds. The main components were subjected to a target network approach. Drug-likeness screening gave 20 compounds with predictive blood–brain barrier permeation. Compound target network identified six key compounds, namely nerol, citronellol, geraniol, geranic acid, cis-3-hexen-1-ol and 1-hexanol. Top enriched terms in GO, KEGG and DisGeNET were mostly related to the central nervous system (CNS). Protein—protein interactions revealed a core network of 14 targets, 11 of which were CNS-related (targets for antidepressants, analgesics, antipsychotics, anti-Alzheimer’s and anti-Parkinson’s agents). This work provides useful information on the production of woody peony essential oils with specific chemotypes and reveals their potential importance in aromatherapy for alternative treatment of CNS disorders.

Study on the Combined Toxicities and Quantitative Characterization of Toxicity Sensitivities of Three Flavor Chemicals and Their Mixtures to Caenorhabditis elegans. ACS OMEGA 2021; 6:35745-35756. [PMID: 34984305 PMCID: PMC8717562 DOI: 10.1021/acsomega.1c05688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 12/03/2021] [Indexed: 05/09/2023]
Abstract
It was shown that flavor chemicals with high toxicity sensitivities mean that small changes in their effective concentrations can lead to significant changes in toxicity. Flavors are widely used in personal care products. However, our study demonstrated that some flavor chemicals and their mixture rays have high toxicity sensitivities to Caenorhabditis elegans (C. elegans), which may have an impact on human health. In this paper, three flavor chemicals (benzyl alcohol, phenethyl alcohol, and cinnamaldehyde) were used as components of the mixture, and three binary mixture systems were constructed, respectively. Five mixture rays were designed for each mixture system by a direct equipartition ray design method. The lethal toxicities of the three flavor chemicals and mixture rays to C. elegans at three exposure volumes were determined. A new concept (inverse of the negative logarithmic concentration span (iSPAN)) was introduced to quantitatively evaluate the toxicity sensitivity of chemicals or mixture rays, and the combination index (CI) was employed to identify the toxicological interactions in the mixtures. It was shown that the three flavor chemicals as well as the binary mixture rays have a significant concentration-response relationship on the lethality of C. elegans. The iSPAN values of the three flavor chemicals and their mixture rays were larger than 3.000, showing very strong toxicity sensitivity to C. elegans. In mixture systems, the toxicity sensitivities of mixture rays with different mixture ratios were also different at different exposure volumes. In addition, it can be seen from the CI heat map that the toxicological interaction not only shows the mixture ratio dependence but also changes with the different exposure volumes, which implies that the mixtures consisting of flavor chemicals with high toxicity sensitivity have complex toxicological interactions. Therefore, in environmental risk assessment, special attention should be paid to chemicals with high toxicity sensitivities.
