本研究的目的是研究丛枝菌根真菌（AMF）的生物量，多酚配置文件和内容的经济上重要的草药殖民的影响。用马郁兰、香蜂草和金盏花进行盆栽实验，应用市售AMP混合物进行接种。利用HPLC-UV-ESI-qTOFMS对主要多酚类化合物进行了紫外-可见光谱和质谱鉴定。对选定的人进行了量化。结果表明，丛枝菌根真菌对不同草本植物的侵染率不同，马郁兰的真菌侵染率最高（82 M%），其次是香蜂草（62 M%）和万寿菊（17 M%）。AMF接种显著增加了马郁兰的生物量（1.5倍），万寿菊花的数量（1.2倍），迷迭香酸和马郁兰（1.5倍）和柠檬香蜂草（1.2倍）的紫草酸异构体的产量。因此，应用优化的AMF接种物可以提高植物材料的数量和质量。
The aim of this study is to examine the effect of arbuscular mycorrhizal fungi (AMF) colonization on biomass, polyphenol profile, and content of economically important herbs. A pot experiment was performed with marjoram, lemon balm, and marigold applying a commercially available AMP mixture for inoculation. Major polyphenols were identified using HPLC-UV-ESI-qTOFMS on the basis of their UV-vis and mass spectral characteristics, and. selected ones were quantified. We showed that AMF can provide different services for each herb. Marjoram had the highest level of fungal colonization (82 M%) followed by lemon balm (62 M%) and marigold (17 M%). AMF inoculation significantly increased the biomass of marjoram (1.5-fold), the number of marigold flowers (1.2-fold), and the yield of rosmarinic acid and lithospermic acid isomers of marjoram (1.5-fold) and lemon balm (1.2-fold). Therefore, the quantity and quality of plant material could be improved by the application of optimized AMF inoculum.
