Effect of hydroalcoholic extracts of Nasturtium officinale leaves on lipid profile in high-fat diet rats

AIM OF THE STUDY: Nasturtium officinale R. Br. (Brassicaceae) is used as a home remedy in Iran as a cardioprotective agent without any scientific background. In this investigation an attempt was made to study the effect of Nasturtium officinale hydroalcoholic extract (NOE) on serum lipid profile which is closely associated with many cardiovascular diseases. MATERIALS AND METHODS: Accordingly, serum total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) were among the parameters investigated. We also evaluated the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels as a measure of hepatic cell damages. RESULTS: Intragastric administration of NOE (500 mg/kg body weight per day) to groups of hypercholesterolaemic rats for 10 days lowered their serum TC, TG and LDL-C by 34.2, 30.1, and 52.9%, respectively, while raised the serum HDL-C level by 27.0% after 10 days of treatments. Treatment with NOE reduced serum ALT and AST levels compared to high-fat diet groups. CONCLUSIONS: Based on these data, it is concluded that the NOE has definite cardioprotective potential and these results constitute a valid scientific basis for consuming Nasturtium officinale for medicinal application.     

紫外分光光度法测定金莲花口服液含量

目的建立金莲花口服液中黄酮类物质的含量测定方法。方法采用紫外分光光度法,通过紫外扫描确定最大吸收波长,在最大吸收波长处以芦丁为对照品测量吸光度制定标准曲线,并进行样品溶液稳定性试验、重现性试验、精密度试验、回收率试验等。结果精密度试验所测得的吸光度分别为:0.235、0.234、0.234、0.234、0.233,相对标准偏差(RSD)=0.30%,数据表明该试验具有良好的精密度;稳定性试验测定在0、5、10、15、20、25min时吸光度分别为0.249、0.249、0.248、0.245、0.245、0.244,RSD=0.83%,数据表明在25min内对待测物进行吸光度的测定是稳定的;重现性试验在500nm波长处测定吸光度为:0.412、0.411、0.413、0.407、0.407,RSD=0.69%,表示重现性良好;回收率试验测定的平均回收率为98.5%,RSD=0.56%;样品含量的测定测定的3种批号样本的平均含量分别为0.334mg/ml、0.412mg/ml、0.375mg/ml。结论紫外分光光度法简单方便、准确可靠,可以用来测定金莲花口服液中黄酮类物质的含量。

Efficacy and safety of a combination herbal medicinal product containing Tropaeoli majoris herba and Armoraciae rusticanae radix for the prophylactic treatment of patients with respiratory tract diseases: a randomised,prospective, double-blind,placebo-controlled phase III trial

Abstract

Objective:

The aim of this ICH-GCP study was to investigate the efficacy and safety of a prophylactic administration of a combination herbal medicinal product (CHMP) in two dosages compared to placebo with respect to the incidence of new occurring infections of the respiratory tract (RTI). Clinical experience of prophylactic treatment of respiratory tract infections with the marketed CHMP containing horseradish root (Armoraciae rusticanae radix) and nasturtium (Tropaeoli majoris herba) has existed for decades.     

Nasturtium Officinale L. hydroalcoholic extract improved oxymetholone‐induced oxidative injury in mouse testis and sperm parameters

Testicular tissue and sex hormones are sensitive to the anabolic steroids (oxymetholone/OM) due to increased free radical damage and hormonal changes. The Nasturtium officinale L. have various antioxidant compounds. The aim of the present study was to investigate N. officinale effect on OM‐induced oxidative injury in mouse testis and sperm parameters. Thirty BALB/c mice were divided into five groups, including control, OM (5 ml/kg) and three N. officinale doses (25, 50 and 100 mg/kg) + OM. At the end of the study (40 days), serum luteinising hormone (LH), follicle‐stimulating hormone (FSH), testosterone, nitric oxide (NO) levels, ferric reducing ability of power (FRAP) and testis stereological factors were measured. The sperm parameters were evaluated. Liquid chromatography‐electrospray ionisation‐tandem mass spectrometry (LC‐ESI/MS) analysis was yielded a fingerprint of N. officinale phenolic constituents. 100 mg/kg of N. officinale extract significantly reduced the serum level of testosterone and a significant increase in LH and FSH in comparison with the control group. This dose also significantly improved the stereological factors and sperm parameters. 50 and 100 mg/kg of N. officinale extract significantly increased the testis tissue FRAP levels, and 100 doses reduced the serum levels of NO. Fourteen compounds and 34 peaks were identified in the extract with LC‐ESI/MS. Nasturtium officinale extract has protective effects against testicular toxicity caused by OM.     

旱金莲提取物祛斑作用的实验研究

为研究旱金莲提取物对黑素瘤B16细胞的作用，建立鼠B16黑素瘤细胞培养体系，在添加旱金莲提取物后，测定黑素瘤细胞活力、酪氨酸酶活性以及黑素含量的变化，并与氢醌的实验结果进行比较。结果显示旱金莲提取物抑制人黑素细胞酪氨酸酶活性及黑素合成，具有药物浓度依赖性关系，对黑素细胞的活力影响较小。提示旱金莲提取物具有抑制黑素合成的功效，可作为美白剂进一步开发研究。
