Ecological and soil physiochemical parameters impact the crop quality and development. In spite of the huge commercial prospective, the phytonutrient and chemometric profiles of Himalayan oregano (Origanum vulgare L.) have not been evaluated, and their relationships with ecological parameters are still lacking. The objective of this research study was to evaluate the disparity in the phytonutrient profiles of different ecotypes of O. vulgare in wild and cultivated populations and determine whether such variation was related to the diverse climatic and edaphic conditions prevailing in the northwestern Himalayas. Micrometeorological, atomic absorption spectroscopy for micro-elemental analysis was determined for soil. HPLC was used to determine the disparity in phytonutrient (quercetin, betacarotene, ascorbic acid, and catechin) and phytochemical (arbutin) levels. Cultivated populations had lower phytonutrient levels than wild populations. The habitat exhibiting pH values ranging from 6 to 7 elevated organic carbon (2.42%), nitrogen (97.41 kg ha), and manganese (10-12 μg g) and zinc contents (0.39-0.50%) show luxirant growth of Origanum vulgarel. The phytonutrient (quercetin, betacarotene, ascorbic acid, arbutin, and catechin) levels had a direct relationship with UV-B flux (r = 0.82) and potassium (r = 0.97). Wild accessions predominantly contained catechin and ascorbic acid, with maximum values of 163.8 and 46.88 μg g, respectively, while the cultivated accessions had the highest level of arbutin (53.42 μg g). Maximum variation was observed in quercetin (114.61%) followed by β-carotene (87.53%). Cultivated accessions had less quercetin (0.04-1.25 μg g) than wild accessions (1.25-2.87 μg g). Wild accessions had higher phytonutrient values for catechin, β-carotene, and ascorbic acid while cultivated accessions had maximum values for arbutin. The correlation of environmental variables with phytonutrient levels paves the way for metabolomic-guided enhancement of agricultural practices for better herb quality.
生态和土壤理化参数影响作物质量和发育。尽管具有巨大的商业前景，但喜马拉雅山牛至（Origanum vulgare L.）的植物营养素和化学计量学特征尚未得到评估，其与生态参数的关系仍不清楚。本研究旨在评估野生和栽培种群中不同生态型的牛至植物营养素谱的差异，并确定这种变化是否与西北喜马拉雅地区普遍存在的不同气候和土壤条件有关。对土壤进行了微量气象学和原子吸收光谱法进行微量元素分析。HPLC 用于测定植物营养素（槲皮素、β-胡萝卜素、抗坏血酸和儿茶素）和植物化学物质（熊果苷）水平的差异。栽培种群的植物营养素水平低于野生种群。表现出 pH 值在 6 到 7 之间的生境提高了有机碳（2.42%）、氮（97.41 kg ha）和锰（10-12 μg g）和锌含量（0.39-0.50%），牛至生长旺盛。植物营养素（槲皮素、β-胡萝卜素、抗坏血酸、熊果苷和儿茶素）水平与 UV-B 通量（r = 0.82）和钾（r = 0.97）呈直接关系。野生品种主要含有儿茶素和抗坏血酸，分别达到最大值 163.8 和 46.88 μg g，而栽培品种的熊果苷含量最高（53.42 μg g）。槲皮素的变化最大（114.61%），其次是β-胡萝卜素（87.53%）。栽培品种的槲皮素含量低于野生品种（0.04-1.25 μg g）（1.25-2.87 μg g）。野生品种的儿茶素、β-胡萝卜素和抗坏血酸的植物营养素值较高，而栽培品种的熊果苷值最高。环境变量与植物营养素水平的相关性为代谢组学指导的农业实践增强铺平了道路，以提高草药质量。
