Chemical Investigation on the Volatile Part of the CO 2 Supercritical Fluid Extract of Infected Aquilaria sinensis (Chinese Agarwood). Molecules 2024; 29:2297. [PMID: 38792158 PMCID: PMC11124402 DOI: 10.3390/molecules29102297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 05/10/2024] [Accepted: 05/10/2024] [Indexed: 05/26/2024] Open
Abstract
This work is focused on the characterization of the composition of a CO2 supercritical fluid extract of Aquilaria sinensis (Chinese agarwood) collected in the Dongguan area (China) and infected by mechanical methods. The constituents of this extract were analyzed by gas chromatography-mass spectrometry (GC-MS) and quantified accurately by gas chromatography with a flame ionization detector (GC-FID), using an internal reference and predicted response factors. Since a significant number of components of this extract remained non-identified after the initial GC-MS analysis of the whole extract, its fractionation by chromatography on silica gel helped to characterize several additional constituents by isolation and structural analysis by NMR spectroscopy. The main components are the classical agarwood chromones (Flindersia chromone and its mono-, di-, and trimethoxylated analogues (respectively, 11.01% and 0.11-4.02%) along with sesquiterpenic constituents typically found in agarwood essential oils, like baimuxinal (1.90%) and kusunol (1.24%), as well as less common selinane dialdehydes (1.58-2.27%) recently described in the literature. Moreover, the structure and stereochemistry of a new sesquiterpenic alcohol, 14β,15β-dimethyl-7αH-eremophila-9,11-dien-8β-ol (0.67%), was determined unambiguously by the combination of structural analysis (NMR, MS), hemisynthesis, and total synthesis, leading to dihydrokaranone and a neopetasane epimer.

ACTA ACUST UNITED AC 2015; 49:e4872.

Abstract
(+)-Dehydrofukinone (DHF) is a major component of the essential oil of
Nectandra grandiflora (Lauraceae), and exerts a depressant effect
on the central nervous system of fish. However, the neuronal mechanism underlying DHF
action remains unknown. This study aimed to investigate the action of DHF on
GABAA receptors using a silver catfish (Rhamdia
quelen) model. Additionally, we investigated the effect of DHF exposure on
stress-induced cortisol modulation. Chemical identification was performed using gas
chromatography-mass spectrometry and purity was evaluated using gas chromatography
with a flame ionization detector. To an aquarium, we applied between 2.5 and 50 mg/L
DHF diluted in ethanol, in combination with 42.7 mg/L diazepam. DHF within the range
of 10-20 mg/L acted collaboratively in combination with diazepam, but the sedative
action of DHF was reversed by 3 mg/L flumazenil. Additionally, fish exposed for 24 h
to 2.5-20 mg/L DHF showed no side effects and there was sustained sedation during the
first 12 h of drug exposure with 10-20 mg/L DHF. DHF pretreatment did not increase
plasma cortisol levels in fish subjected to a stress protocol. Moreover, the
stress-induced cortisol peak was absent following pretreatment with 20 mg/L DHF. DHF
proved to be a relatively safe sedative or anesthetic, which interacts with GABAergic
and cortisol pathways in fish.

Abstract
The chemical composition of root extracts of the title species collected at 20 different places in the Hengduan Mountains of China was examined. From these samples, a total of 17 eremophilane derivatives were isolated, three of which were new franoeremophilane derivatives: 3beta-acetoxy-6beta-(angeloyloxy)furanoeremophilan-10beta-ol, 1alpha-acetoxyfuranoeremophilan-15,6alpha-olide, and 6beta-[2-(hydroxymethyl)prop-2-enoyloxy]furanoeremophil-1(10)-ene. Based on the chemical composition, the samples could be classified into as many as seven types: one type containing non-furanoeremophilane derivatives and the other six containing furanoeremophilane derivatives with different oxidation levels. Results of DNA sequencing of the atpB-rbcL region and the internal transcribed spacers of the ribosomal RNA gene also indicated a high diversity in the species.
