Sanchi flowers were traditionally used as functional medicinal ingredient in materials. The study was aimed at evaluating superfine powder product of Sanchi flower, hence in this study, five fractions of dried Sanchi flower powders (SFP) were prepared at variable particle sizes by superfine grinding and evaluated for changes in various properties. Superfine powder with median particle diameter of 25.57 μm was produced through grinding. It was evident from the environmental scanning electron microscopy analysis that during superfine grinding, mechanical shear stress played its crucial role in breakdown of the SFP and causes increases in surface area owing to reduction of particle sizes. Superfine grinding could improve solubility, oil holding capacity, and brightness, but decrease the fluidity of SFP. SFP with smallest particle size exhibited highest saponin, minerals, total phenolic, and flavonoid contents accompanied with the best antioxidant activities. Size reduction beyond M200 and M400 led to increasing tendency in IR signature band patterns and marked differences in peak intensities while the powdered samples showed resemblance with respect to peak shapes. Differential scanning calorimetry indicated the lowest melting temperature for SFP fraction with smallest particle size. Conclusively, superfine SFP due to inherent improvement in properties may render several potential applications in manufacturing of food and pharmaceutical additives to impart improved functionalities of finally finished products with uniformity.

三七花传统上被用作材料中的功能药用成分。该研究旨在评估三七花的超细粉产品，因此在本研究中，通过超细研磨制备了五种不同粒径的干三七花粉 (SFP)，并评估了各种性质的变化。通过研磨得到中值粒径为25.57 μm的超细粉体。从环境扫描电子显微镜分析中可以明显看出，在超细研磨过程中，机械剪切应力在 SFP 的分解中起着至关重要的作用，并且由于颗粒尺寸的减小而导致表面积增加。超细研磨可以提高溶解性、持油能力和亮度，但会降低SFP的流动性。粒径最小的 SFP 具有最高的皂苷、矿物质、总酚和黄酮含量，同时具有最好的抗氧化活性。超过 M200 和 M400 的尺寸减小导致 IR 特征带模式的增加趋势和峰强度的显着差异，而粉末样品在峰形方面表现出相似性。差示扫描量热法表明具有最小粒径的 SFP 部分的最低熔化温度。总之，由于特性的固有改进，超细 SFP 可能会在食品和药物添加剂的制造中提供多种潜在应用，以赋予最终成品具有均匀性的改进功能。超过 M200 和 M400 的尺寸减小导致 IR 特征带模式的增加趋势和峰强度的显着差异，而粉末样品在峰形方面表现出相似性。差示扫描量热法表明具有最小粒径的 SFP 部分的最低熔化温度。总之，由于特性的固有改进，超细 SFP 可能会在食品和药物添加剂的制造中提供多种潜在应用，以赋予最终成品具有均匀性的改进功能。超过 M200 和 M400 的尺寸减小导致 IR 特征带模式的增加趋势和峰强度的显着差异，而粉末样品在峰形方面表现出相似性。差示扫描量热法表明具有最小粒径的 SFP 部分的最低熔化温度。总之，由于特性的固有改进，超细 SFP 可能会在食品和药物添加剂的制造中提供多种潜在应用，以赋予最终成品具有均匀性的改进功能。差示扫描量热法表明具有最小粒径的 SFP 部分的最低熔化温度。总之，由于特性的固有改进，超细 SFP 可能会在食品和药物添加剂的制造中提供多种潜在应用，以赋予最终成品具有均匀性的改进功能。差示扫描量热法表明具有最小粒径的 SFP 部分的最低熔化温度。总之，由于特性的固有改进，超细 SFP 可能会在食品和药物添加剂的制造中提供多种潜在应用，以赋予最终成品具有均匀性的改进功能。
