摘要

摘要 木槿属锦葵科开花植物。木槿广泛分布于热带和亚热带地区,不仅在观赏方面发挥着重要作用,在传统医药方面也发挥着重要作用。本研究从木槿花粉中分离出了七种化合物,包括一种新化合物 mukungarrole(1)和六种已知的黄酮类衍生物(2-7)。在分离出的化合物中,山奈酚(2)和长春花苷 B(3)具有抗氧化活性。此外,新化合物 mukungarrole (1) 与山奈酚 (2) 和异鼠李素-7-O-鼠李糖苷 (5) 一起显示出抑制α-葡萄糖苷酶的活性,其与α-葡萄糖苷酶的相互作用已通过分子对接分析得到证实。对五个芙蓉属植物品种的进一步比较表明,这五个品种都含有长春花苷 B(3)和山奈酚-7-O-鼠李糖苷(4)作为主要成分,并表现出抗氧化和抑制α-葡萄糖苷酶的活性。然而,由于木槿品种不同,长春花苷 B(3)和山奈酚-7-O-鼠李糖苷(4)以及次要成分的含量也存在差异,从而导致了功效的不同。这项研究证明,H. syriacus花粉及其成分具有抗氧化和抑制α-葡萄糖苷酶的潜力,其含量和功效因芙蓉品种而异。

Antioxidant and α-glucosidase inhibitory potential of the pollen of Hibiscus spp.

Abstract

Hibiscus species are flowering plants of the Malvaceae family. Hibiscus are widely distributed in tropical and subtropical regions and play an important role not only in ornamental aspects but also traditional medicine. In this study, seven compounds, mukungarrole (1), a new compound and six known flavonoid derivatives (27) were isolated from Hibiscus syriacus pollen. Among the isolated compounds, kaempferol (2) and vincetoxicoside B (3) showed antioxidant activity. Additonally, the new compound, mukungarrole (1), along with kaempferol (2) and isorhamnetin-7-O-rhamnoside (5), showed α-glucosidase inhibitory activity and its interaction with α-glucosidase was confirmed using molecular docking analysis. Further comparison of five varieties of Hibiscus spp. showed that all five species contained vincetoxicoside B (3) and kaempferol-7-O-rhamnoside (4) as major components and exhibited antioxidant and α-glucosidase inhibitory activities. However, there was differences in the content of vincetoxicoside B (3) and kaempferol-7-O-rhamnoside (4) and minor components depending on of Hibiscus variety, which contributed to differences in efficacy. This study proves that H. syriacus pollen and its constituents have antioxidant and α-glucosidase inhibitory potentials and the content and efficacy vary depending on Hibiscus species.
