나무수국 꽃의 Secoiridoid, Iridoid 및 Flavonol 배당체의 골격근세포 비대 유도 효능

초록

Five secoiridoids (1-3, 5, 10), a iridoid (4) three flavonol glycosides (7-9) and a coumarin (6), were isolated from the flowers of Hydrangea paniculata. Their chemical structures were elucidated as kingiside (1), morroniside (2), sweroside (3), loganin (4), vogeloside (5), umbelliferone (6), quercetin-3-O-sambubioside (7), quercetin-3-O-neohesperidoside (8), kae-mpferol 3-O-sambubioside (9) and secologanin dimethyl acetal (10), respectively, by spectroscopic analysis. All isolated compounds 1-10 were assessed for their ability to induce C2C12 myotube hypertrophy. Among them, loganin (4) and kaempferol 3-O-sambubioside (9) increase the diameter of C2C12 myotubes. All isolated compounds 1-10 were firstly reported from the flowers of Hydrangea paniculata, and the skeletal muscle hypertrophic activity of 4 and 9 was also reported for the first time. © 2022, Korean Society of Pharmacognosy.
