For centuries, various species from the genus have been utilized in traditional medicine worldwide. A number of ethnopharmacological reports have pointed out that plants can be applied to diminish digestive problems. Among them, (L.) Scop. (Asteraceae) stands out as a promising herbal drug candidate because its constituents exhibit antimicrobial and antioxidant potential, as evidenced by ethnopharmacological reports. As a result, the species is particularly intriguing as an adjunctive therapy for functional gastrointestinal and motility disorders. Our research goal was to verify how the extracts, fractions, and main flavonoids of affect colon contractility under ex vivo conditions. An alternative model with porcine-isolated colon specimens was used to identify the effects of preparations and their primary flavonoids. LC-ESI-MS was utilized to evaluate the impacts of methanol (CP1), methanolic 50% (CP2), and aqueous (CP3) extracts as well as diethyl ether (CP4), ethyl acetate (CP5), and -butanol (CP6) fractions. Additionally, the impacts of four flavonoids, apigenin (API), luteolin (LUT), apigenin 7--glucuronide (A7GLC), and chrysoeriol (CHRY), on spontaneous and acetylcholine-induced motility were assessed under isometric conditions. The results showed that extracts, fractions, and their flavonoids exhibit potent motility-regulating effects on colonic smooth muscle. The motility-regulating effect was observed on spontaneous and acetylcholine-induced contractility. All extracts and fractions exhibited an enhancement of the spontaneous contractility of colonic smooth muscle. For acetylcholine-induced activity, CP1, CP2, and CP4 caused a spasmolytic effect, and CP5 and CP6 had a spasmodic effect. LUT and CHRY showed a spasmolytic effect in the case of spontaneous and acetylcholine-induced activity. In contrast, API and A7GLC showed a contractile effect in the case of spontaneous and pharmacologically induced activity. Considering the results obtained from the study, could potentially provide benefits in the treatment of functional gastrointestinal disorders characterized by hypomotility and hypermotility.
几个世纪以来,世界各地的传统医学一直使用各种 属物种。一些民族药理学报告指出, 植物可用于减少消化问题。其中, (L.)Scop.(菊科)作为一种有前途的草药候选药物脱颖而出,因为其成分表现出抗菌和抗氧化潜力,这一点在民族药理学报告中得到了证实。因此,该物种作为功能性胃肠道和运动障碍的辅助治疗方法特别有趣。我们的研究目标是验证 提取物、馏分和主要类黄酮如何在离体条件下影响结肠收缩性。使用猪分离结肠标本的替代模型来鉴定 制剂及其主要类黄酮的作用。LC-ESI-MS 用于评估甲醇(CP1)、50%甲醇(CP2)和水(CP3)提取物以及二乙醚(CP4)、乙酸乙酯(CP5)和 -丁醇(CP6)馏分的影响。此外,还评估了四种类黄酮,芹菜素(API)、木犀草素(LUT)、芹菜素 7--葡萄糖醛酸苷(A7GLC)和芹菜素(CHRY)对自发性和乙酰胆碱诱导的运动的影响,在等长条件下。结果表明, 提取物、馏分及其类黄酮对结肠平滑肌具有强大的运动调节作用。在自发性和乙酰胆碱诱导的收缩性方面观察到运动调节作用。所有提取物和馏分均增强了结肠平滑肌的自发性收缩性。对于乙酰胆碱诱导的活性,CP1、CP2 和 CP4 引起痉挛性作用,CP5 和 CP6 具有痉挛性作用。LUT 和 CHRY 在自发性和乙酰胆碱诱导的活动中表现出痉挛性作用。相反,API 和 A7GLC 在自发性和药理学诱导的活动中表现出收缩作用。考虑到研究结果, 可能对治疗以低动力和高动力为特征的功能性胃肠道疾病有益。
