L. is a biennial species native to North America and introduced to Europe in the 17th-18th centuries, used in traditional medicine or as a dietary supplement in various products, as well as in cosmetics and the pharmaceutical industry. In recent decades, oil extracted from seeds has been increasingly used for the treatment of various conditions. In this article, we highlight the polyphenolic content of 2 types of extracts from species, collected from the wild flora of Romania, from two regions with different altitudes and pedoclimatic conditions (plains and mountains), namely: OHM-hydroalcoholic extract, Macea sample; OHVD-hydroalcoholic extract, Vatra Dornei; OAM-aqueous extract, Macea sample; OAVD-aqueous extract, Vatra Dornei sample. The LC/MS analysis of the whole plant extracts revealed 5 to 14 polyphenols, depending on the sample location and type of extract, out of which 7 flavonoids are newly reported for this species. Climatic parameters were mapped using QGIS. Higher qualitative and quantitative values of polyphenols were observed in the hydroalcoholic extract obtained from individuals collected from the plain area.
L.是一种原产于北美的两年生植物，于17至18世纪引入欧洲，用于传统医学或作为各种产品中的膳食补充剂，以及用于化妆品和制药行业。近几十年来，从种子中提取的油越来越多地用于治疗各种病症。在本文中，我们重点介绍了从罗马尼亚野生植物群中采集的两种提取物的多酚含量，这些植物来自两个海拔和土壤气候条件不同的地区（平原和山区），即：OHM-水醇提取物，马恰样本；OHVD-水醇提取物，瓦特拉多尔内伊；OAM-水提取物，马恰样本；OAVD-水提取物，瓦特拉多尔内伊样本。对全株提取物的LC/MS分析显示，根据样品位置和提取物类型，含有5至14种多酚，其中有7种黄酮类化合物是该物种新报道的。使用QGIS绘制了气候参数图。从平原地区采集的个体获得的水醇提取物中观察到更高的多酚定性和定量值。
