Abstract

In Asia, has long been used as a spice or seasoning in food to stimulate digestion. In the present study, we evaluated the effects of ethanol extract of (EEAT) on menopausal osteoporosis and obesity. After the administration of EEAT in ovariectomy (OVX) mice models for five weeks, microcomputed tomography and a histological analysis were performed to assess, respectively, the trabecular structure and the fat accumulation in adipose, liver, and bone tissues. We also examined the effects of EEAT on a bone marrow macrophage model of osteoclastogenesis by in vitro stimulation from the receptor activator of nuclear factor-kappa Β ligand (RANKL) through real-time PCR and Western blot analysis. In addition, ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) with authentic standards was applied to characterize the phytochemical profiling of EEAT. We found that EEAT significantly decreased OVX-induced body weight gain and fat accumulation, significantly prevented OVX-induced deterioration of bone mineral density and microstructure of trabecular tissues, and significantly inhibited osteoclast differentiation by downregulating NF-κB/Fos/NFATc1 signaling in osteoclasts. Furthermore, UHPLC-MS/MS identified eight beneficial phytochemicals in EEAT. Collectively, these results suggest that EEAT might be an effective nutraceutical candidate to attenuate menopausal osteoporosis by inhibiting osteoclastogenesis and to prevent obesity by suppressing fat accumulation.

摘要

在亚洲, 一直被用作食物中的香料或调味料,以刺激消化。在本研究中,我们评估了 乙醇提取物(EEAT)对绝经后骨质疏松症和肥胖的影响。在给予 EEAT 五周后,对去卵巢(OVX)小鼠模型进行了微计算机断层扫描和组织学分析,分别评估了小梁结构和脂肪在脂肪、肝脏和骨骼组织中的积累。我们还通过核因子-κB 配体(RANKL)受体激活剂的体外刺激,通过实时 PCR 和 Western blot 分析,检查了 EEAT 对骨髓破骨细胞形成模型的影响。此外,采用带有标准品的超高效液相色谱-串联质谱(UHPLC-MS/MS)对 EEAT 的植物化学特征进行了表征。我们发现,EEAT 可显著降低 OVX 诱导的体重增加和脂肪积累,显著防止 OVX 引起的骨密度和小梁组织微观结构恶化,并通过下调破骨细胞中的 NF-κB/Fos/NFATc1 信号通路,显著抑制破骨细胞分化。此外,UHPLC-MS/MS 在 EEAT 中鉴定出 8 种有益的植物化学物质。综上所述,这些结果表明,EEAT 可能是一种有效的天然产物候选物,通过抑制破骨细胞形成来减轻绝经后骨质疏松症,通过抑制脂肪积累来预防肥胖。
