[PMID: 37746728 DOI: 10.1080/14786419.2023.2261137] [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: 07/13/2023] [Accepted: 09/13/2023] [Indexed: 09/26/2023]
Abstract
The chemical composition of the essential oil from the fruits and leaves of Litsea cubeba (Lour.) Pers. (Lauraceae) growing wild in Baoshan region, Yunnan Province of China was investigated for the first time in 5.36% and 2.16% (w/w) yields, respectively, when analysed by GC and GC/MS. Ten and 25 components were identified in the fruit and leaf oils which constituted 99.15% and 99.4% of the oils. Of the fruit oil, the major components were neral (36.51%), geranial (44.23%), and citronella (8.77%). The major components of the leaf oil were linalool (67.37%), limonene (6.37%), β-bisabolene (6.03%), neral (5.86%), and caryophyllene oxide (3.20%). The analysis of the essential oil obtained from Baoshan revealed a significant abundance of citral and linalool in the fruits and leaves, respectively. This was the first Litsea species to exhibit β-bisabolene as the principal constituent.

Jalas Essential Oil: An Ally against Oral Pathogens and Mouth Health. Molecules 2023; 28:4803.

Abstract
The genus Thymus L., belonging to the Lamiaceae family, contains about 220 species with a distribution that mainly extends in Europe, northwest Africa, Ethiopia, Asia, and southern Greenland. Due to their excellent biological properties, fresh and/or dried leaves and aerial parts of several Thymus ssp. have been utilized in the traditional medicine of many countries. To evaluate not only the chemical aspects but also the biological properties, the essential oils (EOs), obtained from the pre-flowering and flowering aerial parts of Thymus richardii subsp. nitidus (Guss.) Jalas, endemic to Marettimo Island (Sicily, Italy), were investigated. The chemical composition of the EOs, obtained by classical hydrodistillation and GC-MS and GC-FID analyses, showed the occurrence of similar amounts of monoterpene hydrocarbons, oxygenated monoterpenes, and sesquiterpene hydrocarbons. The main constituents of the pre-flowering oil were β-bisabolene (28.54%), p-cymene (24.45%), and thymol methyl ether (15.90%). The EO obtained from the flowering aerial parts showed as principal metabolites β-bisabolene (17.91%), thymol (16.26%), and limonene (15.59%). The EO of the flowering aerial parts, and its main pure constituents, β-bisabolene, thymol, limonene, p-cymene, and thymol methyl ether were investigated for their antimicrobial activity against oral pathogens and for their antibiofilm and antioxidant properties.

Abstract
Thyme is the common name of many taxa belonging to the Thymbra and Thymus genera. Given the economic importance of thyme oils, many thyme species have been studied and their essential oils and other volatile-containing extracts chemically characterized. Thymbra and Thymus species are frequent in the west Mediterranean region, considered to be the centre of origin of the genus Thymus, and extend further westwards in the Iberian Peninsula and northwest Africa, to the Macaronesian region in the Atlantic Ocean. The present work gives an overview of the chemical composition of the volatiles from the taxa of these two genera occurring in the above geographic area.

Abstract
The extracts of four rare plants found on the islands of Sicily, Vulcano and Marettimo, Southern Italy, were screened for their inhibitory effect on the production of leukotriene B4 by 5-lipoxygenase in intact cells. The methanol extracts of pods of Cytisus aeolicus and aerial parts of Thymus richardii were the most active extracts, inhibiting almost completely the leukotriene B4 production at 200 and 50 microg/ml, respectively.
