Eight field-grown species (, , , , , , and ) were analyzed for their mucilage content to identify the species with the highest yield. The mucilage was extracted with boiling water, precipitated by methanol, and subjected to acid hydrolysis by trifluoroacetic acid. Although mucilage content varied across species, root yields generally exceeded flower yields, with roots reaching up to 26.43 %. HPLC analysis showed glucose as the dominant monosaccharide in root mucilage across all species. Rhamnose and fructose content, however, exhibited variations among the species. Field emission scanning electron microscopy micrographs showed layered or fibrous structures, while Fourier Transform Infrared Spectroscopy analysis confirmed a polysaccharide-based composition for flower and root mucilage. Energy dispersive X-ray analysis detected calcium, phosphorus, and magnesium, with higher concentrations in flower mucilage. X-Ray diffraction analysis confirmed the presence of both amorphous and semi-crystalline regions within the mucilage samples, with crystalline phases identified as calcium oxalate hydrate, alpha-cyclodextrin, and glutamic acid. In conclusion, flowers and roots yielded the highest mucilage content, suggesting as a promising source of polysaccharides with potential applications in the pharmaceutical and food industries.

在对伊朗 Alcea 属的多物种探索中揭示粘液的复杂性


对八种田间种植的物种（、、、、、、、和）的粘液含量进行了分析，以确定产量最高的物种。将粘液用沸水提取，用甲醇沉淀，并用三氟乙酸进行酸水解。尽管粘液含量因物种而异，但根产量普遍超过花产量，根达到26.43%。 HPLC 分析显示葡萄糖是所有物种根粘液中的主要单糖。然而，鼠李糖和果糖含量在物种之间表现出差异。场发射扫描电子显微镜显微照片显示出层状或纤维状结构，而傅里叶变换红外光谱分析证实了花和根粘液的多糖成分。能量色散 X 射线分析检测到钙、磷和镁，其中花粘液中的浓度较高。 X 射线衍射分析证实了粘液样品中存在无定形和半结晶区域，其中结晶相被确定为草酸钙水合物、α-环糊精和谷氨酸。总之，花和根产生的粘液含量最高，表明其是一种有前景的多糖来源，在制药和食品工业中具有潜在的应用前景。
