In this study, three main tests were investigated including; Pharmachological effect of the plant extraction, Biochemical effect of the ethanolic extract and Effect of Nepetaseptemcrenata ethanolic extract on liver lysosomal enzymes, total protein, DNA and RNA. The results reviewed that antipyretic effect is the decreasing of the temperature of the hyperthermic rats, theethanolic extract of Nepetaseptemcenata which given interperotential to rats with inflamed paw in a dose of (1/5 LD50 & 1/10 LD50) significantly decreased the thickness of the inflamed rats' paw as compared with the control group and standard group after 6 hours. The ethanolic extract of Nepetaseptemcrenata in a dose of 1.1 and 50.5 mg/kg, induced protection against writhing response andreaches its maximum effect in a dose of 1.1 mg/kg. In theAntibacterial activity the investigation of antimicrobial activities of Nepetaseptemcrenataextract revealed that it has no activity against S. aureus and a very weak antiseptic action against E. coli. Finally, Nepetaseptemcrenata hasmuch medicinal prosperity. Keywords- Nepetaseptemcenata, Antioxidant, Egypt. INTRODUCTION their extracts have been used for medicinal purposes1. Some species of Nepeta germs Nepeta is one of the most important genera are utilized in folk medicine for treatment of of lamiaceae family with regard to the contusions, rheumatic pains, fever, number of its species. Some species of this cutaneous eruption and some species are 2 genus are important medicinal plants and used for their anti-inflammatory properties . Nepeta plants were prepared as tea and used Page 157 www.ajethno.com American Journal of Ethnomedicine _____________________________ ISSN: 2348-9502 in traditional medicine as anthelmintics, MATERIAL AND METHODS febrifuges, expectorants and to treat bronchitis, bites as well as stings of Pharmacological effect of the plant scorpions3. extraction Nepetaseptemcrenata is an erect This experiment was undertaken to slender plant with branches at base leaves determine the analgesic, antipyretic and anti- are oppositely alternated, ovate with crenate inflammatory activities of the ethanolic or slightly dentate margins. This plant is extract of Nepetaseptemecrenata. Mice were found in Saint Catherine, Sinai, Egypt4. used to measure the analgesic activity, Nepetaseptemcrenata known to be used by whereas rats were selected to measure the the native Bedouins in folk medicine as antipyretic and anti-inflammatory activities antipyretic, sedative, cardiotonic, eye wash of the extract. Animals of these experiments and as a gargle in sore throat5. An were exposed to the ethanolic extract in isopimarance type diterpence and 7-omethyl doses equal to 101 mg/kg (1/10 LD50) & apigenin were isolated from the ethanolic 50.5 mg/kg (1/20 LD50) for mice and 101 extract of Nepetaseptemcernata herb6,5 mg/kg (1/5 LD50) & 50.5 mg/kg (1/20 LD50) investigated the chemical constituents of &50.5 mg/kg (1/10 LD50) for rats. Thus Nepetaseptemcrenata and 7analyzed the several test activities have been done upon volatile oil of the same plant species8. those animals: Analgesic Activity (Acetic Reported that the lactone- free hot water acid induced writhing test), antipyretic extract of catnip (Nepetacatrina) causes a activity, anti-inflammatory activity and significant decrease in the wakefulness and antimicrobial activity. an increase in sleep behavior, particularly deep sleep. A few members of genus Biochemical effect of the ethanolic extract Nepetaare reported to posses biological Sample of blood were collected activities especially reduction of serum using the orbital sinus technique (Sanford, lipids and inflammatory effects6. 1954) after 2, 4, 8, 16 and 24 hours of Nepetais used in traditional medicine treatments for determining the following as laxative; to treat dysentery, kidney and parameters: Lipid peroxidation as liver diseases and teeth troubles9.
