Low sclareol by‐product of clary sage concrete: chemical analysis of a waste product of the perfume industry

ABSTRACT

In line with the sustainable development objectives of the Claryssime® research programme, a by‐product of Salvia sclarea concrete (low sclareol by‐product) obtained from industrial sclareol purification, was subjected to full chemical fractionation, characterization and assessment of its economic potential as a by‐product synergy candidate. Fractionation and intensive semi‐preparative high‐performance liquid chromatography isolation led to the characterization of several compounds that belong to different metabolite families, including flavonoids [salvigenin (3), 1.8%], diterpenoids [sclareol (6), 4.6%] and triterpenoids [oleanolic acid (10), 6.2%], and triacylglycerols (60.8%). The triacylglycerol fraction was further studied: its total fatty acid content was analysed by gas chromatography–mass spectrometry and all the triacylglycerols were described by ultra‐performance liquid chromatography–quadrupole time of flight mass spectrometry (UPLC‐QToF) analysis. The reproducibility of the low sclareol by‐product chemical composition was assessed and validated by quantitative high‐performance liquid chromatography–evaporative light scattering detector analysis and its evolution during the process was investigated via the analysis of a rich sclareol by‐product. Such an analytical approach, from the improved fractionation to the triacylglycerol analysis via UPLC‐QToF, can be applied to many industrial concretes or other by‐products from natural ingredient extraction.
