Lipophilic phytochemicals from sugarcane bagasse and straw

Abstract

The composition of lipophilic phytochemicals in sugarcane bagasse and straw, the two major residues of sugarcane processing, was investigated in detail by gas chromatography and mass spectrometry. The composition of the lipids from sugarcane bagasse and straw was completely different from each other. While the extracts of sugarcane bagasse were dominated by n-aldehydes (ca. 48% of all identified lipids) and n-fatty alcohols (ca. 23%) with lower amounts of n-fatty acids (10%) and steroid ketones (14%), the extracts from sugarcane straw were strongly dominated by n-fatty acids (accounting for ca. 60% of all identified compounds) with significant amounts of steroid compounds, particularly sterols (10%) and steroid ketones (14%). Tocopherols and triterpenols were also found, being particularly abundant among the extractives of sugarcane straw. Sugarcane bagasse and straw can thus be considered as promising feedstocks for obtaining highly valuable phytochemicals of nutraceutical or pharmaceutical interest.

Biogenic platinum from agricultural wastes extract for improved methanol oxidation reaction in direct methanol fuel cell

“…In this study, agriculture waste products from sugarcane bagasse ( Saccharum officinarum L.), pineapple peel ( Ananas comosus L.) and banana peel ( Musa paradisiaca ) were selected to fully realize the zero-value of residue waste to high-value functionalization material in the synthesis Pt nanoparticles. The bagasse and fruit peels are polymer complexes that mainly contain cellulose, hemicellulose and lignin, which contain aromatic and phenolic groups that make them suitable as green reducing and stabilizing agents [18] . Sugarcane has flavonoids such as apigenin, luteolin and tricin derivatives, as well as compounds of high phenolic acids such as caffeic acid, sinapic acid, and hydroxycinnamic which allow antioxidant activity [19] , [20] , [21] .…”

Bioactive Sugarcane Lipids in a Circular Economy Context

“…Río et al [ 21 ] studied the lipophilic phytochemicals from sugarcane straw and bagasse wastes. Bagasse lipophilic extracts were mainly composed of n- aldehydes (48% of all identified lipids) and n-fatty alcohols (23%), steroid ketones (14%) and n-fatty acids (10%), while straw extracts contained n-fatty acids (60% of all identified compounds), sterols (10%) and steroid ketones (14%).…”

Phytosterols and Novel Triterpenes Recovered from Industrial Fermentation Coproducts Exert In Vitro Anti-Inflammatory Activity in Macrophages

“…Moreover, it must be noted that, as previously mentioned, in general, the fermentative processes use sugar/molasses as carbon and energy sources. The producing plant (i.e., sugarcane) has been described as containing phytochemicals [ 28 , 29 ], also associated with anti-inflammatory properties in macrophages and mice [ 30 ]. Thus, it can be hypothesized that some of those potentially bioactive molecules could be found and recovered in the fermentation biowastes.…”
