The aim of this study was to assess the efficiency of different drying methods (room, sun, oven, microwave, cross-flow, infra-red, dehumidifier, and freeze-drying) on maximum retention of the nutritional and bioactive compounds profiling of Talinum triangulare, which is a less-known perishable leafy-vegetable. The evaluation of various drying methods is to learn the best appropriate strategy for a post-harvest drying method for retaining all the potential benefits with minor loss. Microwave and freeze-dried samples held the maximum ascorbic acid quantified by HPLC with 1.36 and 1.11 g/100 g DW, respectively. The main carotenoid compounds identified were violaxanthin, lutein, zeaxanthin, β-carotene isomers, trans-β-carotene, and cis-β-carotenes. Gallic, protocatechuic, catechin, para-coumaric, ferulic, rutin, trans-cinnamic, and quercetin are the significant phenolics and flavonoids identified and quantified by liquid chromatography. The efficiency of different solvents on bioactive extractions uncovered that the methanol and 80% aqueous ethanol were good for retention of total phenolics, total flavonoids, and antioxidant compounds, which was affirmed through phosphomolybdate, DPPH, and FRAP assays. Dried T. triangulare foliage could be productively utilized as a promising raw material for food and pharma businesses because of its rich bioactive composition.

各种干燥方法对三角楸叶生物活性物质、抗坏血酸和抗氧化潜力的评价

本研究的目的是评估不同干燥方法（房间、阳光、烤箱、微波、错流、红外线、除湿和冷冻干燥）对最大保留 Talinum 的营养和生物活性化合物分析的效率三角形，这是一种鲜为人知的易腐烂的绿叶蔬菜。对各种干燥方法的评估是为了学习收获后干燥方法的最佳适当策略，以保留所有潜在的好处，而损失很小。微波和冻干样品通过 HPLC 测定的最大抗坏血酸含量分别为 1.36 和 1.11 g/100 g DW。鉴定出的主要类胡萝卜素化合物是紫黄质、叶黄素、玉米黄质、β-胡萝卜素异构体、反式-β-胡萝卜素和顺式-β-胡萝卜素。没食子酸、原儿茶酸、儿茶素、副香豆酸、阿魏酸、芦丁、反式肉桂酸、槲皮素和槲皮素是通过液相色谱法鉴定和定量的重要酚类和黄酮类化合物。不同溶剂对生物活性提取的效率表明，甲醇和 80% 乙醇水溶液有利于保留总酚类、总黄酮类和抗氧化化合物，磷钼酸盐、DPPH 和 FRAP 测定证实了这一点。由于其丰富的生物活性成分，干燥的三角木树叶可以有效地用作食品和制药企业的有前途的原材料。通过磷钼酸盐、DPPH 和 FRAP 测定证实了这一点。由于其丰富的生物活性成分，干燥的三角木树叶可以有效地用作食品和制药企业的有前途的原材料。通过磷钼酸盐、DPPH 和 FRAP 测定证实了这一点。由于其丰富的生物活性成分，干燥的三角木树叶可以有效地用作食品和制药企业的有前途的原材料。
