摘要

采用微波辅助萃取法（MAE）从龙舌兰鹰嘴豆渣中提取了β-谷甾醇（BSS）和β-谷甾醇葡萄糖苷（BSSG）。通过高效薄层色谱（HPTLC）、傅立叶变换红外光谱（FT-IR）、高效液相色谱-质谱联用（HPLC-MS）和气相色谱-质谱联用（GC-MS）对 BSS 和 BSSG 进行了定量和表征。与 BSSG（每克提取物干重含 61.6 毫克 β-谷甾醇葡萄糖苷）相比，使用 MAE 萃取 9 秒钟，可获得更多的 BSS（每克提取物干重含 103.6 毫克 β-谷甾醇）。MAE 是一种从 A. angustifolia 甘蔗渣中高效回收 β-谷甾醇（BSS）和 β-谷甾醇葡萄糖苷（BSSG）的有效方法。这丰富了有关植物化学提取的科学知识，并为制药和营养保健品等各种行业带来了巨大潜力。此外，通过龙舌兰产业副产品的价值评估，这项研究有助于资源的可持续利用，符合绿色和循环经济实践的原则。

Microwave-assisted extraction of β-Sitosterol: A by-product from Agave angustifolia Haw bagasse

β-sitosterol (BSS) and β-sitosterol glucoside (BSSG) were extracted from Agave angustifolia Haw bagasse using microwave-assisted extraction (MAE). The quantification and characterization of BSS and BSSG were performed through high-performance thin-layer chromatography (HPTLC), Fourier-transform infrared spectroscopy (FT-IR), high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS), and gas chromatography-mass spectrometry (GC-MS). With an extraction time of 9 seconds using MAE, a higher amount of BSS (103.6 mg of β-sitosterol per gram of dry weight of extract) was obtained compared to BSSG (61.6 mg of β-sitosterol glucoside per gram of dry weight of extract). MAE emerges as a promising method for the efficient recovery of β-sitosterol (BSS) and β-sitosterol glucoside (BSSG) from A. angustifolia bagasse. This enriches scientific knowledge regarding phytochemical extraction and holds great potential for various industries, such as pharmaceuticals and nutraceuticals. Additionally, by valorizing the by-products of the agave industry, this research contributes to the sustainable utilization of resources, aligning with the principles of green and circular economy practices.

期刊介绍： The purpose of BioResources is to promote scientific discourse and to foster scientific developments related to sustainable manufacture involving lignocellulosic or woody biomass resources, including wood and agricultural residues. BioResources will focus on advances in science and technology. Emphasis will be placed on bioproducts, bioenergy, papermaking technology, wood products, new manufacturing materials, composite structures, and chemicals derived from lignocellulosic biomass.
