香茅草在多国范围内应用广泛且历史悠久,传统多将其用于烹饪以调味,制成香茅草茶以及作药用等。除保留传统应用外,香茅草在现代的应用多集中于开发香茅草油,其可被用于制备食品添加剂、杀菌剂、化妆品、药品等。香茅草在园林绿化等方面,具有较好的应用前景。香茅草具有特殊的柠檬香味,主要含柠檬醛、月桂烯、芳樟醇、香叶醇、橙花醇、香茅醇等化学成分;其药理作用主要为抗菌、抗炎、镇痛、抗氧化、抗肿瘤、抗焦虑、降压、降血糖等,且随着研究的不断深入,香茅草的一些新的药理作用正逐渐被发现。香茅草在应用形式及保健作用方面,符合现代社会需求及大健康产业的发展趋势,可加大推广力度。 相似文献

The essential oil (EO) from leaves of Cymbopogon citratus increased the reaction time to thermal stimuli both after oral (25 mg/kg) and intraperitoneal (25–100 mg/kg) administration. EO (50–200 mg/kg, p.o. or i.p.) strongly inhibited the acetic acid-induced writhings in mice. In the formalin test, EO (50 and 200 mg/kg, i.p.) inhibited preferentially the second phase of the response, causing inhibitions of 100 and 48% at 200 mg/kg, i.p. and 100 mg/kg, p.o., respectively. On the other hand, the opioid antagonist naloxone blocked the central antinociceptive effect of EO, suggesting that EO acts both at peripheral and central levels. 相似文献

Cymbopogon citratus (DC.) Stapf., commonly known as lemon grass and used, over many years, for medicinal purposes in West Africa, produces a volatile oil on steam extraction of its leaves. The antibacterial properties of the essential oil have been studied. These activities are shown in two of the three main components of the oil identified through chromatographic and mass spectrometric methods. While the alpha-citral (geranial) and beta-citral (neral) components individually elicit antibacterial action on gram-negative and gram-positive organisms, the third component, myrcene, did not show observable antibacterial activity on its own. However, myrcene provided enhanced activities when mixed with either of the other two main components identified. 相似文献

The present study was designed to investigate the hypoglycemic and hypolipidemic effects of the single, daily oral dosing of 125-500 mg/kg of fresh leaf aqueous extract of Cymbopogon citratus Stapf. (CCi) in normal, male Wistar rats for 42 days. The average weights of rats per group were taken at 2 weeks interval for 42 days. On day 43, blood samples from the rats were collected for fasting plasma glucose (FPG), total cholesterol, triglycerides, low-density lipoproteins (LDL-c), very low-density lipoprotein (VLDL-c) and high-density lipoprotein (HDL-c) assays through cardiac puncture under halothane anesthesia. Acute oral dose toxicity study of CCi was also conducted using limit dose test of the Up and Down Procedure statistical program (AOT425StatPgm, Version 1.0) at a dose of 5000 mg/kg body weight/oral route. Our results showed CCi to lower FPG and lipid parameters dose dependently (p<0.05) while raising the plasma HDL-c level (p<0.05) in same dose-related fashion but with no effect on plasma triglycerides level (p>0.05). Results of acute oral toxicity showed CCi to be of low toxicity and as such could be considered relatively safe on acute exposure. Thus, confirming its folkloric use and safety in suspected Type 2 diabetic patients. 相似文献

Objective Psychosocial stress has been implicated in the genesis of psychiatric disorders such as memory deficits, depression, anxiety and addiction. Aqueous leaf extract of Cymbopogon citratus (CYC) otherwise known as lemongrass tea has antidepressant, anxiolytic and anti-amnesic effects in rodents. This study was designed to evaluate if C. citratus could reverse the neurobehavioral and biochemical derangements induced by social defeat stress (SDS) in the resident/intruder paradigm. Methods Intruder male mice were divided into five groups (n = 7): group 1 received saline (10 mL/kg, p.o.; non-stress control), group 2 also received saline (10 mL/kg, p.o.; SDS control) while groups 3?5 had C. citratus (50, 100 and 200 mg/kg, p.o.) daily for 14 d. The SDS was carried out 30 min after each treatment from day 7 to day 14 by exposing each intruder mouse in groups 25 to a 10 min confrontation in the home cage of an aggressive resident counterpart. The neurobehavioral features (spontaneous motor activity-SMA, anxiety, memory, social avoidance and depression were then evaluated. The concentrations of nitrite, malondialdehyde and glutathione as well as acetylcholinesterase activity in the brain tissues were also determined. Results C. citratus (50, 100 and 200 mg/kg) attenuated hypolocomotion, heightened anxiety, depressive-like symptom, memory deficit and social avoidance induced by SDS. The altered levels of oxidative stress and acetyl-cholinesterase in SDS-mice were positively modulated by C. citratus. Conclusion The results of this study suggest that C. citratus might mitigate psychosocial stress-induced neurologic diseases in susceptible individuals. 相似文献
