“…In the VOCs of GL07, we found 2,5‐dihydroxyacetophenone and β‐ionone, which reached a peak on the tenth day, accounting for 9.63% of the total. β‐ionone is a natural species found in plants and is widely used in food, cosmetics, and pharmaceutical industries .…”

Plant endophytes are rich in secondary metabolites and are widely used in medicine, chemical, food, agriculture, and other fields. Here, an endophytic fungus is isolated from Ginkgo biloba L. leaves and identified as Alternaria brassicae GL07 through genotypic characterizations. It can produce fruity scented volatiles. The analysis of volatile organic compounds (VOCs) was done by gas chromatography–mass spectrometry. A total of 32 components were identified; and at different culture times, the composition of VOCs was different. It had more components in the first two weeks, but a fewer components on the 21st day. More olefins, ketone, aldehyde, and alcohol were found in the growth period and more amines and esters were found in the decline period. Also, 2,5‐dihydroxyacetophenone, β‐ionone, and nonanal were found. They were the same ingredients in Ginkgo essential oils and some of them were isolated for the first time in the volatile constituents of endophytes. The antioxidant activity and whitening activities of all extracts were also evaluated. When cultured for 10 days, it had the strongest 2,2‐diphenyl‐2‐picrylhydrazyl radical (IC50, 0.56 g/L), hydroxyl radical scavenging ability (IC50, 0.47 g/L), reducing ability, and tyrosinase inhibition ability (IC50, 5.18 g/L), which may be due to a large amount of ketones and alcohols produced during the log phase. This demonstrates the potential of A. brassicae GL07 to produce bioactive compounds and to be used for perfume and cosmetic industries.

“…For example, β-ionone has the ability to effectively suppress lung carcinogenesis triggered by benzo(a)pyrene [14]. The biosynthetic pathway of β-damascenone and β-ionone is specific, as β-damascenone is formed from xanthophyll, which gives rise to β-carotene, and β-ionone is formed by splitting α-and β-carotene [16].…”

Hydrosols of Veronica Species—Natural Source of Free Volatile Compounds with Potential Pharmacological Interest

et al. 2022

In this study, free volatile compounds (FVCs) were isolated from the water fractions (hydrosols) of 10 Croatian Veronica species obtained by hydrodistillation (HD) and microwave-assisted extraction (MAE). The use of different isolation techniques is important for the analysis of the influence of extraction conditions on the qualitative and quantitative composition of the isolated constituents. The composition of the hydrosols was analyzed using gas chromatography and mass spectrometry. The compounds β-ionone and benzene acetaldehyde were detected in all 10 Veronica hydrosols studied. E-caryophyllene was also identified in all isolates except the MAE isolate of V. arvensis L. Caryophyllene oxide was isolated in all isolates apart from the HD isolate of V. catenata Pennell. (E)-β-Damascenone is significantly present in all isolates except the MAE isolates of V. catanata and V. cymbalaria Bodard. In these two species, α-muurolol was identified in a high percentage. The same basic phytochemical constituents and compounds characteristic of a given Veronica species suggest the importance of further research. Antioxidant activity was tested for all extracts using two methods, ORAC and DPPH. Therefore, it is crucial to identify as many specialized metabolites from Veronica species as possible, especially hydrosols, which are natural products of potential pharmacological interest.
