本研究利用砂仁多糖1（ALP1）与镁（Mg）螯合合成ALP1-Mg（II）复合物（ALP1-Mg）。 基于Box-Behnken响应面设计，最佳工艺条件为22 mg·mL−1柠檬酸三钠、2.10 mol·L−1 MgCl2，在70 ℃反应2.9 h，得到最大Mg含量为2.13%。

2024年9月13日 · In this study, Amomum longiligulare polysaccharide 1 (ALP1) is used to chelate with magnesium (Mg) to synthesize the ALP1-Mg (II) complex (ALP1-Mg). Based on Box-Behnken response surface design, the optimum technological conditions are 22 mg mL -1 trisodium citrate, 2.10 mol L -1 MgCl 2, reaction at 70 °C for 2.9 h, resulting in a maximum Mg ...

2025年2月22日 · ALP1 supplementation improves piglet growth by significantly increasing the jejunal VH/CD ratio. Gut microbiota is modulated by ALP1, increasing beneficial bacteria like Lactobacillus. EA metabolite from Lactobacillus promotes jejunal epithelial cell proliferation.

2024年1月29日 · ALP1升高：见于肝外胆管梗阻，如转移性肝癌、肝脓肿、肝淤血等并可伴有ALP2的升高。 ALP2的增高：肝内胆管梗阻所致胆汁淤积，如原发性肝癌及急性黄疸性肝炎，ALP1相对减少。

本发明一种促进文昌鸡生长性能的海南砂仁多糖‑镁络合物及其制备工艺，将ALP1‑Mg作为饲料添加剂应用于文昌鸡的养殖，提高文昌鸡养殖的经济效益，为中药多糖饲料添加剂的开发提供借鉴，这有利于文昌鸡养殖业的发展，同时也有利于中药多糖的发展。

海南砂仁多糖 (alp1)是海南砂仁的主要活性成分之一，具有促生长、免疫调节和抗氧化等作用，有望成为应用于文昌鸡的促生长类药物饲料添加剂。

2021年10月1日 · Amomum longiligulare polysaccharides 1 (ALP1) was a glucosan that possessed an immune enhancement ability. However, disadvantages including short biological half-life hindered the application of ALP1. To solve these shortcomings, ALP1 was successfully prepared to nanoparticles (ALPP) with poly (lactic-co-glycolic acid) in the present study.

Abstract In this study, Amomum longiligulare polysaccharide 1 (ALP1) is used to chelate with magnesium (Mg) to synthesize the ALP1‐Mg (II) complex (ALP1‐Mg).
