Abstract:
اجريت الدراسة الحالية للتحري عن المركبات النشطة الموجودة في المستخلص الخام المائي والميثانولي لاوراق الاس والنعناع والريحان ودراسة تاثيرها على فعالية انزيم الاسيتل كولين استريز ومستوى الدهون ومستوى السكر ومستوى انزيمات الكبد(ALP وSGPT وSGOT) ومستوى الانتر | The present study was conducted to investigate the active constituents found in aqueous and methanolic crude leaf extracts of Myrtus communis, Mentha piperita and Ocimum basilicum, and studies it effect on the acetylcholinesterase activity, levels of lipids, level of glucose, level of liver enzymes (ALP, SGPT and SGOT) and level of Interleukins (IL - 2, IL - 4, IL - 6 and IL - 10) in laboratory mice (in vivo). The results of the phytochemical analysis of the crude aqueous and methanolic extracts of Myrtus communis, Mentha piperita and Ocimum basilicum contain active compounds : Phenols, Flavonoids and Tannins and missing of Steroids and Coumarines in all extract but Saponins and Alkaloids found in alcoholic extract only, while terpens were present in Mentha piperita and Ocimum basilicum and absent in Myrtus communis. The results of administrating animals with different extracts showed no significant difference on blood Acetylcholinesterase (AchE) compared with ethanol liquid diet, while the alcoholic and aqueous extracts of M. communis, M. piperita and O. basilicum in the serum of decreased Acetylcholinesterase level significantly(p?0.05), liver and brain [(1.25 ?pH/30 min, 1.23 ?pH/30 min, 1.28 ?pH/30 min, 1.20 ?pH/30 min, 1.26 ?pH/30 min, 1.28 ?pH/30 min), (0.35 ?pH/30 min, 0.34 ?pH/30 min, 0.34?pH/30 min, 0.36?pH/30 min, 0.42?pH/30 min, 0.39?pH/30 min), (0.32?pH/30 min, 0.37?pH/30 min, 0.39?pH/30 min, 0.36?pH/30 min, 0.34?pH/30 min, 0.37?pH/30 min)] respectively compared with animals fed on ethanol liquid diet [(1.37 ?pH/30 min), (0.47 ?pH/30 min), (0.45 ?pH/30 min)] respectively. The methanolic and aqueous extracts of M. communis, M. piperita and O. basilicum reported a significant decrease in level of the total cholesterol and Low Density Lipoprotein (LDL) [(181mg/dl, 186mg/dl, 175mg/dl, 172mg/dl, 181mg/dl, 184mg/dl), (118mg/dl, 121mg/dl, 114mg/dl, 109mg/dl, 118mg/dl and 120mg/dl)] respectively, when compared with animals fed on ethanol liquid diet [(195 mg/dl), (132mg/dl) ] respectively while no effect was reported on High Density lipoprotein. The level of triglyceride reduced after the treatment with ethanol liquid diet, and then the level increased after the treatment with M. communis and O. basilicum extracts. The methanolic and aqueous extracts of M. communis, M. piperita and O. basilicum have led to a reduction in the level of glucose in the serum which increased after the treatment with ethanol liquid diet. Methanolic and aqueous extracts decreased the liver enzymes (ALP, SGPT and SGOT) significantly to the normal level (18, 17, 21, 18, 20 and 21) KAU, (19, 19, 16, 13, 17, 17) IU/L and (21, 24, 17, 15, 17 and 19) IU/L respectively after the increase by the treatment with ethanol liquid diet (24) KAU, (26) IU/L, (28) IU/L as compared to control (20) KAU, (12.2) IU/L, (13.5) IU/L, respectively. The level of Interleukin - 2 and Interleukin - 4 in the serum significantly increased in the treatment of alcoholic and aqueous extract of M. communis, M. piperita and O. basilicum [(18 pg /ml, 17 pg /ml, 20 pg /ml, 18 pg /ml, 20 pg /ml, 20 pg /ml), (100 pg/ml, 110 pg/ml, 119 pg/ml, 108 pg/ml, 90 pg/ml, 92pg/ml)] in comparison with ethanol liquid diet treatment [(14 pg /ml), (77 pg/ml)] respectively. While the level of Interleukin - 6 and Interleukin - 10 increased significantly in the serum, when animals were fed with ethanol liquid diet [(259pg/ml) and (501pg/ml)] respectively, and then decreased significantly after the treatment of methanolic, aqueous extract of M. communis, M. piperita and O. basilicum reported [(198 pg/ml, 202pg/ml, 202pg/ml, 201pg/ml, 214pg/ml, 217pg/ml), (370 pg/ml, 385pg/ml, 200pg/ml, 280pg/ml, 350pg/ml and 350pg/ml)] respectively.
