Two new neolignans, syripinnalignins A and B ( 1 and 2 , resp.), were isolated from the 95% EtOH extract of the stem of Syringa pinnatifolia Hemsl . var. alashanensis. The structures of 1 and 2 were elucidated by spectroscopic methods, including UV, IR, HR‐ESI‐MS, and extensive 1D‐ and 2D‐NMR techniques. 相似文献

Chemical investigation of Syringa velutina Kom. led to the isolation of two new secoiridoid glucosides. Their structures were identified as 6'-0-(6, 7-dihyrofoliamenthoyl)-8-epi-kingisidic acid (syrveoside A, 1) and 6'-O-menthiafoloyl-8-epi-kingisidic acid (syrveoside B, 2) on the basis of chemical and physicochemical evidence. 相似文献

Phenylpropanoids from Medicinal Plants: Distribution, Classification, Structural Analysis, and Biological Activity 总被引:3,自引:0,他引:3
V. A. Kurkin 《Chemistry of Natural Compounds》2003,39(2):123-153
The literature and our own research results on phenylpropanoids from medicinal plants were reviewed and systematized. Data were presented for the distribution of phenylpropanoids. Their classification was proposed. The biological structure-activity relationships for compounds found in roseroot (Rhodiola rosea), thorny eleutherococcus (Eleutherococus senticosus), common lilac (Syringa vulgaris), purple echinacea (Echinacea purpurea), medicinal melissa (Melissa officinalis), variegated milk-thistle (Silybum marianum), and others were discussed. 相似文献

One new norlignan, namely noralashinol A (1), one known analogue (2), together with seven known lignans (3–9) were isolated from the stem barks of Syringa pinnatifolia. Their structures were elucidated extensively by spectroscopic methods, including mass spectrometry and 1D and 2D NMR spectroscopies. Compound 8 significantly inhibited NO production in LPS-induced BV-2 murine microglia cells with its IC50 value of 20.7 μM, compared to a positive control quercetin with its IC50 value of 15.3 μM. 相似文献

Osteoblasts and osteoclasts play a pivotal role in maintaining bone homeostasis, of which excessive bone resorption by osteoclasts can cause osteoporosis and various bone diseases. However, current osteoporosis treatments have many side effects, and research on new treatments that can replace these treatments is ongoing. Therefore, in this study, the roles of ligustroside (LGS) and oleoside dimethylester (ODE), a natural product-derived compound isolated from Syringa oblata subsp. dilatata as a novel, natural product-derived osteoporosis treatments were investigated. In the results of this study, LGS and ODE inhibited the differentiation of receptor activator of nuclear factor kappa-Β ligand (RANKL)-induced RAW264.7 cells into osteoclasts without cytotoxicity, and down-regulated the activity of TRAP, a specific biomarker of osteoclasts. In addition, it inhibited bone resorption and actin ring formation, which are important functions and features of osteoclasts. Also, the effects of LGS and ODE on the mitogen-activated protein kinase (MAPK) and nuclear factor kappa-light-chain-enhancer of activated B (NF-κB) and phosphoinositide 3-kinases (PI3K)/ protein kinase B (Akt)/mechanistic target of rapamycin (mTOR) signaling pathways that play important roles in osteoclast differentiation were evaluated. In the results, LGS and ODE downregulated the phosphorylation of RANKL-induced MAPK and PI3K/Akt/mTOR proteins in a concentration-dependent manner, translocation of NF-κB into the nucleus was inhibited. As a result, the compounds LGS and ODE isolated from S. oblate subsp. dilatata effectively regulated the differentiation of RANKL-induced osteoclasts and inhibited the phosphorylation of signaling pathways that play a pivotal role in osteoclast differentiation. Therefore, these results suggest the possibility of LGS and ODE as new natural product treatments for bone diseases caused by excessive osteoclasts. 相似文献

Metabolite profile, antioxidant and antinociceptive activities of Syringa vulgaris bark and leaf methanolic extracts were investigated. By means of HPLC-DAD-ESI-TOF and HPLC-DAD-ESI-MS/MS, a total of 33 phenolics were identified, including 15 secoiridoids, 6 phenylpropanoids, 3 flavonoids, 3 lignans and 6 low molecular weight phenols. Validated quantitative analysis show that syringin (2.52%) and rutin (1.13%) are the main phenolic compounds in bark and leaf, respectively. Notable radical scavenging and antinociceptive activities of the bark and leaf extracts were confirmed by in vitro DPPH● and ABTS●+ assays and by in vivo hot-plate method in mice, respectively. Our results could lay the scientific basic of future clinical perspectives of lilac bark and leaf. 相似文献

紫丁香硬枝扦插技术的研究 总被引:4,自引:0,他引:4
通过试验研究了不同浓度ABT1、ABT2种生长调节剂对紫丁香枝条不同部位插条成活率的影响,结果表明,枝条中下部插穗的成活率明显高于枝条上部(带顶芽)插穗,达50%,且中下部插穗在株高、茎粗、侧根数、平均根长方面都优于上部。不同浓度的ABT1、ABT2对紫丁香硬枝扦插生根均有促进作用,用生长调节剂处理后的插惩在株高、茎粗、侧根数、平均根长方面都好于对照,其中采用500μg/mL的ABT2对枝条中下部插穗进行处理的成活率最高,达到62.5%。 相似文献
