Abstract: In this study, we have examined the yield of extracted substances obtained by means of extraction using 70 % ethanol (v/v), the content of total phenols and flavonoids, as well as the antioxidant activity of the extracts obtained from the samples of the herbs dried by means of different techniques. Wild mint Mentha longifolia (L.) Hudson was dried naturally in a laboratory oven at a temperature of 45 °C and in an absorptive low temperature condensation oven at 35°C. The highest yield of extracts was obtained from the naturally dried herbs and the lowest from the herbs dried in the low temperature condensation drying oven. The content of total phenols and flavonoids was determined by spectrophotometric methods with an FC reagent and by the complexation reaction with aluminium-chloride, respectively. The extract of the naturally dried herbs had the highest overall content of phenols (113.8±2.0 mg of gallic acid/g of the dry extract) and flavonoids (106.7±0.3 mg of rutin/g of the dry extract). The highest antioxidant activity determined by the FRAP and DPPH assay was determined in the extracts obtained from naturally dried herbs (2.76±0.15 mmol Fe2+/mg of the dry extract and EC50=0.022±0.001 mg/ml), while the lowest was obtained from the extracts of herbs dried in the laboratory oven (1.13±0.11 mmol Fe2+/mg of the dry extract and EC50=0.033±0.001 mg/ml). The HPLC-DAD analysis result show that the greatest content of phenolic compounds show extract obtained from naturally dried plant material. The dominant phenolic component in the all extracts is Kaempferol 3-O-glucoside. The content of all phenolic compound strongly depend on the drying conditions.

Abstract: The effect of Mentha longifolia (L.) leaf hydroalcoholic extract (MLE) was examined on rat ileal smooth muscle contractions. Last portion of ileum from male adult Wistar rat was mounted in an organ bath containing Tyrode solution. The tissue was contracted by carbachol (CCh, 10 μM), KCl (60 mM) and BaCl2 (4 mM) and then MLE (0.0625-1 mg mL-1) was added to the bath cumulatively. The effect of MLE on KCl-induced contraction was examined after tissue incubation with propranolol (1 μM), naloxone (1 μM) and Nω-nitro-L-arginine methyl ester (L-NAME, 100 μM). The effect of MLE on CaCl2-induced ileal contraction in Ca2+-free with high potassium Tyrode solution was also evaluated. The role of potassium channels was examined by ileum incubation (5 min) with tetraethylammonium (TEA, 1 mM). The results showed that KCl-, CCh and BaCl2-induced ileal contractions were inhibited (p<0.001) by cumulative concentrations of MLE with the same potency. In addition, MLE (0.25-1 mg mL-1) inhibited (p<0.01) ileal contractions induced by CaCl2 (0.45-2.7 mM) in a concentration-related manner. The antispasmodic effect of MLE was affected neither by propranolol, L-NAME nor by naloxone. The MLE concentration-response curve was shifted to the right (p<0.05) by tissue incubation with TEA. From results it may be suggested that Mentha longifolia hydroalcoholic leaf extract induces its spasmolytic activity mainly through disturbance in calcium mobilization and partly by potassium channels activation. Present results show that Mentha longifolia leaf extract exerts relaxant effects on intestinal smooth muscle, consistent with the traditional use of the plant to treat gastrointestinal disorders such as diarrhea and colic.

Abstract: The article analyzed the histo-anatomy of the vegetative organs of species Mentha longifolia (L.) Huds collected from Negre ti (Vaslui). On the surface of the vegetative organs was identified the presence of tectorial and secretory hairs. Volatile oil was extracted from the aerial parts of the plant using a Clevenger device, and with a GC-MS (Gas Chromatography coupled with mass spectrometry) there were identified the chemical compounds. It was recorded the presence of 25 chemical compounds, five of them representing 75.42% of the total obtained oil.

Abstract: Topsin M is a common systemic fungicide used as protective/curative substance for alimentary and medicinal plants. That is why it is relevant to evaluate the influence of Topsin M upon the anatomical features of Mentha longifolia, a volatile oil producing medicinal plant and parental species for the hybrid Mentha×piperita. We analysed the anatomical features using cross section through vegetative organs (stems and leaves) belonging to treated and untreated plants. The structure of epidermis in the leaves of Mentha longifolia L. (Huds.) was studied by scanning electron microscopy (SEM).We noticed more quantitative changes than qualitative changes under antifungal Topsin M treatment.

Abstract: Topsin M is a common systemic fungicide used as protective/curative substance for alimentary and medicinal plants. That is why it is relevant to evaluate the influence of topsin M upon the morphological features of Mentha longifolia, a volatile oil producing medicinal plant and parental species for the hybrid Mentha × piperita. We noticed statistical significant variations (oneway Anova) of the dimensional features of the leaves from topsin M treated plants comparing to the control.

Purpose: Premature ovarian failure (POF) includes cessation of normal ovarian function before age 40, causing amenorrhea, menopausal symptoms and general health problems. Hormone replacement therapy (HRT) can be administered in order to prevent menopausal symptoms, osteoporosis and vascular complications. Due to the contraindications and side effects of HRT and the increasing demand for alternative therapeutic modalities, we used Mentha longifolia, which is known in the Iranian traditional medicine (ITM), as being able to cause menstrual bleeding in women with early amenorrhea and decreased FSH serum. Methods: In this pilot study, we report twenty seven amenorrheic women with POF who were referred to the Iranian traditional medicine clinic in Tehran and treated by Mentha longifolia. All those patients had high FSH levels and amenorrhea. They were in their fertility age, between 30 to 40 years old. They were asked to take a cup of herbal tea which was steeped with Mentha longifolia tea three times a day for 2 weeks in 3 menstural cycles. If the patients developed menstruation, the FSH serum level was measured immediately; otherwise they had an FSH measurement one month after the beginning of therapy. Results: Mean age of patients was 36.44 ± 1.5 years. Mean FSH level before treatment was 79.13 ± 19.17 mIU/ml, and after treatment was 27.83 ± 16.14 mIU/ml. In four patients who did not have any response, mean range of FSH was 82.37 ± 19.75 mIU/ml before treatment and afterwards it was 81.97 ± 21.52 mIU/ml. After treatment with herbal teas, there was a significant decrease in FSH (79.39 ± 19.17 to 27.83 ± 16.14 mIU/ml, p value < 0.001). All patient except four (14.81%) had mensturation after taking the herbal medicine. Those four patients showed no decrease in FSH level. More of the patients who used medicinal tea achieved regular monthly bleeding when followed for three cycles.

Abstract: The essential oils from Mentha viridis (L). L. and Mentha pulegium L. were studied to assess their inhibitory potential on phospholipase from snake venoms and to determine their cytogenotoxic action on human cells. These essential oils were able to inhibit the breakdown of phospholipids induced by venoms of snakes of the Bothrops genus. Both oils presented hemolytic activity, although the

Abstract: A double-blind, randomized, placebo-controlled, multicenter study was conducted in 120 women with secondary amenorrhea and oligomenorrhea. Treatment consisted of sequential oral syrup, 45 ml (15 ml three times a day) for 2 weeks. If the patients did not have menstruation after 2 weeks of taking the medication, we would wait for two more weeks. If the patients had menstruation at each stage of using the drug, we started it one week after the end of menstruation. But if the patients had not menstruate after four weeks (two-week using of drug and waiting for two more weeks), the previous steps were repeated. The drug and placebo were repeated in three cycles of menstruation. Bleeding was documented by the patient on diary cards. The primary outcome variable was the occurrence (yes/no) of bleeding during the first treatment cycle. The secondary efficacy outcome was the regularity of bleeding pattern during the three cycles of the study.The number of women with bleeding during the first cycle were higher in the drug group as in the placebo group (68.3% vs. 13.6%; p?<?0.001). The regularity of bleeding throughout the study was markedly better in the drug group compared with those given placebo (33.3% vs. 3.3%; p?<?0.001). No notable complication or side effect was reported in relation to Mentha longifolia L. syrup.In conclusion, Mentha longifolia L. syrup is a safe, well-tolerated, and effective choice in inducing bleeding and maintaining regular bleeding in women with secondary amenorrhea and oligomenorrhea.Secondary amenorrhea (SA) is defined as the cessation of menses for 6 months in female previously irregular menstrual pattern, or the cessation of menses for 3 consecutive months [1]. It has, on the other hand, been specifically defined in various ways, some of which overlap with oligomenorrhea (infrequent menstrual flow at intervals of 39 days to 6 months or 5–7 cycles in a year) [2,3]. The overall prevalence of secondary amenorrhea in among women of reproductive age

Abstract: An attempt has been conducted to evaluate the effect of habek on performance and immunity of broiler chickens. Five levels of whole habek, 0, 25, 100, 150 and 200 g/kg were incorporated into basal diet of 125 broilers for 5 weeks. The results of the study showed that including 150 g/kg habek into broiler diet make a significant improvement in the mean body weight, daily average gain, feed intake and food conversion ratio. However, in another experiment, habek had no effect on the immune response of the birds against Newcastle disease virus live vaccine when a group of 25 birds was given basal diet supplemented with 150 g/kg habek compare to that fed basal diet only.

Abstract: In this study, carvone-scend clones of selected mint (Mentha sp.) from Turkey were studied for their yield, essential oil through field experiments in Randomized Block Design under semi-arid conditions in 1999 and 2000 in Central Anatolia of Turkey. Crops were harvested twice in the vegetation period of each year. Yield varied significantly and significant interactions occurred between year and clones. The greatest fresh herbage yield occurred for Clone 19 (M. villoso-nervata) in the first year and Clone 16 (M. logifolia) and Clone 8 (M. spicata) in the second year. Essential oil content for clones and for cutting periods varied significantly. Interaction between clones and cutting periods was significant. All clones, except Clone 25 (M. spicata) in first year, had high essential oil content in second cutting of both years due to the warmer periods. The greatest oil contents (3.77%) occurred for Clone 16 (M. longifolia). Carvone content ranged from 78.3 to 82.2% for Clone 12 (M. spicata), which yielded the greatest amount. Based on the results, the clones with high herbage yields and high essential oil and carvone contents are selected and used in the further variety improvements studies.
