摘要

众所周知,食品与生物活性之间的关系为创新和新型食品的发展开辟了广阔的前景,以维持或改善健康,增加了对具有药用效果的先进产品的研究需求。Withania somnifera在印度也被称为“Ashwagandha”,是不同古代医学系统中使用最多的植物之一。本研究旨在建立以知识为基础的概念和开发功能性食品的质量控制方法。该研究考虑了标准化标准,并检查了(印度)不同的地理位置或不同的田间地点将如何影响W. somnifera不同样品中的植物成分及其分布。植物成分水平受土壤质量、品种和生长季节的影响较大。酚类含量、类黄酮含量、抗氧化剂含量和优质产量的增加都与植物成分浓度的增加有关。拉贾斯坦邦(18.61%,m/m)、西孟加拉邦(11.21%)和中央邦(12.67%)的水甲醇提取率最高(回流法)、超声法(20 min)和浸渍法(16 h)。其中,拉贾斯坦邦甲醇提取物(回流(索氏)法)总黄酮含量最高(65.32 mg槲皮素当量(QE)/g),总酚含量最高(60.35 mg没食子酸当量(GAE)/g),中央邦甲醇提取物(蒸馏水回流(索氏)法)抗氧化剂含量最高(74.13%)。以V(乙酸乙酯):V(甲苯):V(乙酸) = 9.1:1:6 .6为流动相进行色谱分离。采用气相色谱-质谱(GC-MS)对印度3个不同地区的苦楝水甲醇索氏提取物进行了分析,分别在拉贾斯坦邦、西孟加拉邦和中央邦样品中鉴定出132种、107种和164种植物化学物质。总而言之,本研究表明,在综合农业实践的框架内,产量和植物化学物质如何融合到功能食品的新范式中。

Exploring phytochemicals of Withania somnifera from different vicinity for functional foods

The well-known relation between food and bioactives explores the great prospective of innovative and novel food to maintain or improve health, increasing the demand investigating advance products with medicinal effect. Withania somnifera also known as ‘Ashwagandha’ in India, is one of the most utilized plants in different ancient medicine systems. The present work is an effort to develop a knowledge-based concept and a quality control approach for the development of functional foods. The study took into account the standardization criteria and examined how different geographies or different field sites (of India) would influence the phytoconstituents and their distribution in the different samples of W. somnifera. Phytoconstituents level were strongly influenced by soil quality, cultivar, and growing season. An increase in phenolic content, flavonoid content, antioxidants and the quality yield, were all correlated with increased phytoconstituent concentrations. The highest hydro-methanolic extract yield (by reflux (Soxhlet), sonication (20 min) and maceration (16 h) was from the sample collected from Rajasthan (18.61%, m/m) followed by West Bengal (11.21%) and Madhya Pradesh (12.67%) respectively. The methanolic extract of Rajasthan sample (produced by the reflux (Soxhlet) extraction method) had the highest concentrations of flavonoids (65.32 mg quercetin equivalent (QE)/g) and the total phenols (60.35 mg gallic acid equivalent (GAE)/g), while Madhya Pradesh sample (distilled water reflux (Soxhlet)) extract had the highest antioxidant content (74.13 %). High performance thin layer chromatography (HPTLC) method was also utilized for identification of withanolides A. Chromatographic separations were carried out using V(ethyl acetate):V(toluene): V(acetic acid) = 9.1:1:0.6 as the mobile phase. The gas chromatograph-mass spectrometer (GC-MS) study of hydro-methanolic Soxhlet extract of W. somnifera from 3 different regions of India was done and the total phytochemical substances identified were 132 in sample from Rajasthan, 107 in sample from West Bengal, and 164 in sample from Madhya Pradesh respectively. To conclude, the present study demonstrates how, within a framework of integrated agricultural practices, yield and phytochemicals merge into a new paradigm of functional foods.
