Simultaneous Determination of Kaempferide, Kaempferol and Isorhamnetin in Rat Plasma by Ultra-High Performance Liquid Chromatography-Tandem Mass Spectrometry and its Application to a Pharmacokinetic Study

A selective, rapid and sensitive method using ultra-high performance liquid chromatography was developed and used for the simultaneous determination of kaempferide, kaempferol, and isorhamnetin in rat plasma after oral administration of Sedumsarmentosum Bunge extract. A 6430 triple-quadrupole tandem mass spectrometer in multiple reaction monitoring mode, with a negative electrospray ionization source, was used for the detection. A Waters Symmetry C18 column with isocratic elution (methanol:5 mM ammonium acetate at 75:25, v/v) was used for separation at a flow rate of 0.3 mL min-1. The method was linear for all analytes over the investigated concentration range (r > 0.9900). The intra- and inter-day precisions ranged between 3.88 and 7.74% and the accuracies ranged between 88.63 and 98.74%. The mean recoveries and matrix effect were higher than 85.66 and 92.36%, respectively. All the three compounds tested were stable during storage and analyses. The method was successfully applied to a pharmacokinetic study.

Cryptotanshinone downregulates the profibrotic activities of hypertrophic scar fibroblasts and accelerates wound healing: A potential therapy for the reduction of skin scarring.

Hypertrophic scar (HS) is a skin fibrotic disease that causes major clinically problematic symptoms. Cryptotanshinone (CT) is an important ingredient of Danshen (Salvia miltiorrhiza Bunge extract) that has been used to treat cardio-cerebral vascular diseases. Its clinical efficacy in HS remains unclear. To investigate whether CT can inhibit HS fibrosis, HS-derived fibroblastic cells (HSFs) were established and treated with or without CT. Type-collagen-I (Col1), type-collagen-III (Col3) and α-smooth muscle actin (α-SMA) expression were measured by western blot and real-time quantitative polymerase chain reaction. HSFs migration and contraction were assessed with the scratch assay and the fibroblast-populated collagen lattice (FPCL) contraction assay, respectively. Wound healing in CT-treated Balb/c mice was assessed by immunohistochemical analysis of collagen expression and Masson's trichrome staining analysis of collagen deposition. CT treatment of HSFs down-regulated Col1, Col3 and α-SMA mRNA and protein expression, HSFs migration, and HSFs contraction, and improved FPCL architecture. In mice, CT treatment accelerated wound healing: the scar margins were narrow and there was less collagen deposition in the regenerated tissue. Thus, CT promotes wound healing and decreases excessive deposition of extracellular matrix components. CT may help to prevent and reduce scarring.

Sedum sarmentosum Bunge extract induces apoptosis and inhibits proliferation in pancreatic cancer cells via the hedgehog signaling pathway.

Sedum sarmentosum Bunge, a traditional Chinese herbal medicine, has a wide range of clinical applications including antibiosis, anti-inflammation and anti-oxidation. In the present study, we identified that its extract (SSBE) exerts pancreatic anticancer activity in vitro and in vivo. In the cultured pancreatic cancer PANC-1 cell line, SSBE inhibited cell growth in a concentration-dependent manner, and it was accompanied by the downregulated expression of proliferating cell nuclear antigen (PCNA). In addition, SSBE treatment also increased cellular apoptosis in a mitochondrial-dependent manner. Moreover, SSBE induced p53 expression, reduced c-Myc expression, and inhibited epithelial-mesenchymal transition (EMT). The antiproliferative activity of SSBE in the pancreatic cancer cells was found to be closely related to cell cycle arrest at the G2/M phase by upregulating p21(Waf1/CIP1) expression. Further study showed that this inhibitory effect of SSBE was through downregulation of the activity of the proliferation-related Hedgehog signaling pathway. Exogenous recombinant protein Shh was used to activate Hedgehog signaling, thereby resulting in the abolishment of the SSBE-mediated inhibition of pancreatic cancer cell growth. In animal xenograft models of pancreatic cancer, activated Hedgehog signaling was also observed compared with the vehicle controls, but was reduced by SSBE administration. As a result, SSBE suppressed the growth of pancreatic tumors. Thus, these findings demonstrate that SSBE has therapeutic potential for pancreatic cancer, and this anticancer effect in pancreatic cancer cells is associated with inhibition of the Hedgehog signaling pathway.

Neuroprotection against Aβ25–35-induced apoptosis by Salvia miltiorrhiza extract in SH-SY5Y cells

The neurotoxicity of β-amyloid protein (Aβ) contributes significantly to the pathogenesis of Alzheimer’s disease (AD), and hence the attractive therapeutic strategies focusing on the modulation of Aβ-induced neurotoxicity are warranted. The present study aims to investigate the neuroprotection and underlying mechanisms by which Salvia miltiorrhiza Bunge (Lamiaceae) extract (SME) protects against Aβ25–35-induced apoptosis in SH-SY5Y cells. 2h Pre-treatment of SH-SY5Y cells with SME (0.01, 0.1 or 0.2mg raw herb/ml) concentration-dependently attenuated Aβ25–35-induced cell death, as evidenced by the increase in cell viability and decrease in neuronal apoptosis. In addition, SME suppressed the increased intracellular reactive oxygen species levels, decreased the protein expression of cleaved caspase-3, cytosolic cytochrome c, and Bax/Bcl-2 ratio. These findings taken together suggest that SME provides substantial neuroprotection against Aβ25–35-induced neurotoxicity in SH-SY5Y cells, at least in part, via inhibiting oxidative stress and attenuating the mitochondria-dependent apoptotic pathway. The approach used in this study may also be useful for the screening of therapeutic agents for AD and other related neurodegenerative disease.

자생 산사(Crataegus pinnatifida BUNGE)의 고지혈증 개선 효과

The objective of this study was to investigate the effects of the Crataegus pinnatifida BUNGE extract supplementation of non esterified fatty acid (NEFA), concentrations of serum protein and electrolyte in sera on the hyperlipidemic rats. Concentrations of NEFA and globulin were remarkably lower in the Crataegus pinnatifida BUNGE extract group (HW group) than in the hyperlipidemic group (HD group), but no difference between control group (CO group) and extract of Crataegus pinnatifida BUNGE supplement in control group (NW group). However, concentrations of electrolyte K and A/G were higher in the HW group than HD group. Concentrations of total protein, albumin, electrolyte of total Ca, Pi, Na and Cl were no difference between HW group than HD group. The results indicate that Crataegus pinnatifida BUNGE extract was in the improvement of hyperlipidemic rats.

한국산 산사(Crataegus pinnatifida BUNGE)가 고콜레스테롤혈증 지질농도 변화에 미치는 영향

This study was conducted to observe the influences of Crataegus pinnatifida BUNGE extract on lipid concentration in hypercholesterolemic rats (Sprague Dawley, male) fed the experimental diets for 5 weeks. Body weight gain was remarkably lower in the Crataegus pinnatifida BUNGE extract intake group than in the hypercholesterolemic rats. Total cholesterol concentration was remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Whereas, concentrations of HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol were remarkably higher in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Atherosclerotic index (AI), cardiac risk factor (CRF) were remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. From the above research, Crataegus pinnatifida BUNGE extract was effective on the lipid concentrations in sera of dietary hypercholesterolemic rats.

Sedum sarmentosum Bunge extract exerts renal anti-fibrotic effects in vivo and in vitro

AimsSedum sarmentosum Bunge, a traditional Chinese herbal medicine, has a wide range of clinical effects, including anti-oxidation, anti-inflammation, and anti-cancer properties. In this study, we determined whether S. sarmentosum Bunge Extract (SSBE) has anti-fibrotic effects on renal tissues. Main methodsWe investigated the effects of SSBE on aristolochic acid (AA)-induced injury to renal tubular epithelial cells (RTECs) in vitro and unilateral ureteral obstruction (UUO)-induced renal fibrosis in vivo by evaluating epithelial-to-mesenchymal transition (EMT) and the accumulation of extracellular matrix (ECM) components. Furthermore, we examined the expression levels of TGF-β1 and its receptor. Key findingsIn cultured RTECs (NRK-52E), AA promoted renal EMT and ECM accumulation by up-regulating the expression of mesenchymal markers and ECM components and by down-regulating the expression of epithelial markers. In addition, AA induced an imbalance between MMP-2 and TIMP-2 and enhanced expression of TGF-β1 and its receptor. SSBE treatment significantly inhibited AA-induced TGF-β1 expression and prevented the induction of EMT and deposition of ECM. In the UUO rats, tubular injury and interstitial fibrosis were obviously increased. SSBE administration protected renal function, as indicated by reduced serum creatinine levels, and alleviated renal interstitial fibrosis. These anti-fibrotic effects were associated with a reduction in TGF-β1 expression and inhibition of EMT and ECM accumulation. SignificanceThese findings suggest that SSBE may have therapeutic potential for fibrotic kidney diseases.

감초, 황기 추출물로 블랜칭 처리한 신선편이 연근의 갈변 억제

This study was conducted to inhibit the browning of fresh-cut lotus roots by blanching in a Glycyrrhiza glabra L. and Astragalus membranaceus Bunge extract solution (0.5%). Lotus roots were cut to 1 cm using a knife. The fresh-cut lotus roots were blanched at 50℃ in distilled water (DW, Cont), Glycyrrhiza glabra L. extract solution (GE), and Astragalus membranaceus Bunge extract solution (AE). After treatment, they were packaged with 0.04 mm PE bags and were stored at 10℃ for 12 days. Their color, hardness, DPPH radical scavenging activity, pH, and total soluble solids were then investigated. During storage, the samples treated with GE and AE had high L* values. They were also found to have higher values compared to the control group in the analysis of the browning index. No difference was found, however, in the hardness analysis. With regard to the DPPH radical scavenging activity, the sample treated with Glycyrrhiza glabra L. extract had the highest activity. In the pH analysis, all the groups were found to have a decrease tendency for all the storage periods. The total soluble solids decreased in the control group and slightly increased in the AE and GE groups. These results show that blanching in Glycyrrhiza glabra L. or Astragalus membranaceus Bunge extract is effective for preventing the browning of fresh-cut lotus roots.

Effect of the combinatory mixture of Rubus coreanus Miquel and Astragalus membranaceus Bunge extracts on ovariectomy-induced osteoporosis in mice and anti-RANK signaling effect

Ethnopharmacological relevancePostmenopausal osteoporosis is one of the most common disorders in women after menopause, which is linked to an estrogen deficiency and characterized by an excessive loss of trabecular bone. Rubus coreanus and Astragalus membranaceus have been used for their various pharmacological properties in Asia as a traditional medicine. The present study evaluated the anti-osteoporotic effects of the optimal combination of Rubus coreanus and Astragalus membranaceus in 7:3 mixture (RAM) in ovariectomized (OVX) mice by investigating bone biomechanical properties and the serum levels of TNF-α, osteocalcin, RANKL, OPG, and RANK–RANKL signal-related osteoclast differentiation markers. Materials and methodsA total of 36 mature female outbred ICR (Institute of cancer research) strain mice (7 weeks) were divided into 6 groups with 7 mice in each group as follows: (1) Sham-operated control mice (Sham) received daily oral phosphate-buffered-saline (PBS) of equal volumes through gavage. (2) OVX mice received a daily oral gavage of PBS (OVX). (3) OVX mice were treated daily with 50mg/kgb.w./day of RAM (4) with 100mg/kgb.w./day of RAM or (5) with 200mg/kgb.w./day of RAM via oral gavage. (6) OVX mice received i.p. injections of 17β-estradiol (E2) (0.1mg/kgb.w./day) three times per week for 12 weeks. ResultsMicro-CT images showed that oral administration of RAM to OVX mice prevented tibial bone loss, preserved trabecular bone microarchitecture, and improved bone biomechanical properties. RAM administration also showed recovery effects on the levels of TNF-α, OPG and RANKL concentration in OVX-states. Additionally, we found that the mechanism by which RAM elicited anti-osteoporotic effects was by down-regulating the expression of TRAF6 and NFATc1 in RANKL-RANK pathway, a route of osteoclast differentiation, followed by reducing the production of osteoclast differentiation factors, calcitonin receptors and cathepsin K. ConclusionsOur research strongly suggests that RAM can be clinically used in the prevention and treatment of postmenopausal osteoporosis.

NMR spectroscopy and multivariate statistical analysis of metabonomic changes in Allium macrostemon Bunge extracts induced by different drying methods

Phytomedicines are mostly dried, in different ways, before they are processed and used, which may induce metabolic changes and even lead to some changes in drug efficiency. In this study, we used NMR spectroscopy coupled with multivariate statistical analysis to investigate the metabolic consequences of Allium macrostemon Bunge (AMB) extracts induced by different drying methods, including freeze drying, shade drying, and sun drying. More than 30 metabolites have been detected in AMB extracts, among which two compounds have not been assigned yet. Multivariate statistical analysis showed that different drying methods gave rise to metabolite variations. As a plant osmoprotectant, the proline content was higher in three drying extracts than in the fresh extract. As plant-regulating agents, sugars and amino acids changed differently in each drying extract. Membrane degradation, putrescine formation, tricarboxylic acid cycle, gluconeogenesis and metabolisms mediated by shikimate were also influenced by drying processes. The result indicated that freeze drying may be the appropriate drying method for AMB because of the higher N-trans-feruloyltyramine content, which was a potential effective component of AMB.

Determination and pharmacokinetics of orientin in rabbit plasma by liquid chromatography after intravenous administration of orientin and Trollius chinensis Bunge extract

A high-performance liquid chromatography (HPLC) method was developed and validated for the determination of orientin in rabbit plasma using ultraviolet (UV) absorbance detection. Orientin is the active constituent of purified herbal extract (TRO PE) from the flower of Trollius chinensis Bunge. Protein precipitation was used as the sample preparation technique. A Diamonsil C18 column (150mm×4.6mm, 5μm) was equilibrated with a mobile phase composed of 0.1% acetic acid/methanol/acetonitrile (80/5/15, v/v/v). The calibration curve of orientin in rabbit plasma was linear in the concentration range of 0.530–53.0μg/mL. This validated method was successfully applied to a pharmacokinetic study in rabbits after the intravenous administrations of orientin and TRO PE at three different doses.
