American ginseng ( L.) is known for its health benefits, which are attributed to various terpenoids. However, the specific composition and activities of these terpenoids in forest-grown wild American ginseng remain understudied. This study aimed to characterize the terpenoid composition, particularly triterpene saponins, in forest-grown wild American ginseng. The analysis revealed that triterpene saponins, notably American ginseng ginsenosides (AGGs), are the predominant active components, as identified through LC-MS/MS and HPLC. A subsequent in vitro evaluation of AGGs showcased their potent antioxidant capabilities, displaying the dose-dependent scavenging of free radicals and reducing agents. Moreover, AGGs demonstrated efficacy in reducing oxidative injury and intracellular ROS levels in RAW 264.7 macrophages treated with HO. In addition to their antioxidant properties, AGGs exhibited anti-inflammatory effects, significantly inhibiting NO and inflammatory substance production in lipopolysaccharide-treated RAW 264.7 macrophages. These findings highlight the potential of AGG-rich forest-grown wild American ginseng as a functional food with promising implications for improving human health.
西洋参(L.)因其对健康有益而闻名,这些益处归因于各种萜类化合物。然而,森林中生长的野生西洋参中这些萜类化合物的具体组成和活性仍未得到充分研究。本研究旨在表征森林中生长的野生西洋参中的萜类化合物组成,特别是三萜皂苷。分析表明,通过液相色谱-串联质谱法(LC-MS/MS)和高效液相色谱法(HPLC)鉴定,三萜皂苷,尤其是西洋参皂苷(AGGs)是主要的活性成分。随后对AGGs进行的体外评估显示出它们强大的抗氧化能力,表现出对自由基和还原剂的剂量依赖性清除作用。此外,AGGs在减少用HO处理的RAW 264.7巨噬细胞中的氧化损伤和细胞内活性氧水平方面显示出功效。除了其抗氧化特性外,AGGs还表现出抗炎作用,显著抑制脂多糖处理的RAW 264.7巨噬细胞中一氧化氮和炎性物质的产生。这些发现突出了富含AGG的森林中生长的野生西洋参作为一种功能性食品的潜力,对改善人类健康具有广阔的前景。
