Abstract
Abstract Mango stem bark extracts (MSBE) have been used as bioactive ingredients for nutraceutical, cosmeceutical, and pharmaceutical formulations due to their antioxidant, anti-inflammatory, and analgesic effects. We performed the MSBE preparative column liquid chromatography, which led to the resolution and identification by GC-MS of 64 volatile compounds: 7 hydrocarbons, 3 alcohols, 1 ether, 3 aldehydes/ketones, 7 phenols, 20 terpenoids (hydrocarbons and oxygenated derivatives), 9 steroids, 4 nitrogen compounds, and 1 sulphur compound. Major components were β-elemene, α-guaiene, aromadendrene, hinesol, 1-octadecene, β-eudesmol, methyl linoleate, juniper camphor, hinesol, 9-methyl (3β,5α)-androstan-3-ol, γ-sitosterol, β-chamigrene, 2,5-dihydroxymethyl-phenetylalcohol, N-phenyl-2-naphtaleneamine, and several phenolic compounds. The analysis of MSBE, Haden variety, by GC-MS is reported for the first time, which gives an approach to understand the possible synergistic effect of volatile compounds on its antioxidant, analgesic, and anti-inflammatory effects. The identification of relevant bioactive volatile components from MSBE extracts, mainly terpenes from the eudesmane family, will contribute to correlate its chemical composition to previous determined pharmacological effects.
Highlights
Mango stem bark extract (MSBE) has been developed as a bioactive ingredient for nutraceutical, cosmeceutical, and pharmaceutical formulations due to its antioxidant, anti-inflammatory, and analgesic effects [1]
All previous reported components from the MSBE were analyzed by high performance liquid chromatography with photodiode detection coupled to mass spectrometry (HPLC-DAD-MS), but no report has been published about its volatile components, which are usually analyzed by high resolution gas chromatography coupled to mass spectrometry (GCMS)
We report in this manuscript the MSBE volatiles’ composition from the Haden variety by GC-MS to contribute to its full chemical characterization
Summary
Mango stem bark extract (MSBE) has been developed as a bioactive ingredient for nutraceutical, cosmeceutical, and pharmaceutical formulations due to its antioxidant, anti-inflammatory, and analgesic effects [1]. The composition of polyphenol-rich extracts from mango by-products (stem bark and branch tree) on two varieties (Haden and Tommy Atkins) has been compared, and we concluded that the Haden variety would be the best choice for a future exploitation of mango by-products for the production of polyphenolrich extracts [5]. We report in this manuscript the MSBE volatiles’ composition from the Haden variety by GC-MS to contribute to its full chemical characterization. The possible influence of several volatile components on previous described MSBE health effects (antioxidant and anti-inflammatory)
