(sweet laurel) is one of the volatile oil bearing plants of Lauraceae family. It is cultivated in different parts of Iran and its leaves and fruits have been used in food, cosmetics and pharmaceutical industries. There are a few reports about the effects of some environmental conditions on the quality and quantity of laurel volatiles. The goal of our work was to search the seasonal variations on the <em>L. nobilis</em> leaves volatile composition. The volatiles of four samples of the dried leaves of <em>L. nobilis</em> collected in March, June, September and December 2009 in Isfahan, Iran were prepared by using a Clevenger type apparatus for 3 hours and were analyzed by gas chromatography-mass spectroscopy. Twenty-nine, thirty-one, thirty-three and thirty-four components consisting 96.91%, 97.66%, 97.46% and 95.44% of the total compounds were identified of the volatiles obtained with yields of 1.1%, 1.5%, 1.4% and 0.8% (w/w), subsequently. The main compound was found to be 1,8-cineole (30.80-40.25%). Although twenty-seven out of thirty-six volatile components were similar in different seasons, there were some differences between other compounds of our four samples. While the essential oil composition of the March and June plant samples were characterized by presence of 1,8-cineole, δ-3-carene and camphor, the volatiles of September and December plant samples contained 1,8-cineole, camphene and sabinene. Some compounds like eugenol, methyl eugenol and α-terpenyl acetate were not affected apparently by seasonal changes.https://www.rjpharmacognosy.ir/article_5769_f9f1ce2c69b7cdba2863c8f15cf7c39e.pdf- The Iranian Society of Pharmacognosy

In this paper, the Ferric Reducing Antioxidant Power (FRAP) activity of four Lamiaceae herbal extracts, which traditionally applied in oxidative stress related diseases, has been evaluated and total phenolics contents of these extracts determined by using Folin-Ciocalteu reagent. The aqueous methanol extracts were prepared by percolation method and investigated for antioxidant properties and total phenolics content evaluation. All the extracts showed antioxidant effect from 123.6±4.6 mmol of FeSO<sub>4</sub>.7H<sub>2</sub>Oequivalent/100 g dried extract in <em>Scutellaria tornefortii</em> to 551.5±16.0 mmol of FeSO<sub>4</sub>.7H<sub>2</sub>Oequivalent/100 g dried extract in <em>Satureja sahendica</em>. Interestingly, although <em>Satureja sahendica</em> exhibited the most antioxidant activity, the highest content of polyphenolics belonged to <em>Stachys byzantina.</em> Taking together, antioxidant activity of the mentioned medicinal plants is not necessarily associated with polyphenolic compounds and might be partially due to the presence of other polar constituents like terpenoid-glycosides in aqueous extracts that traditionally used as decoction.https://www.rjpharmacognosy.ir/article_5774_fbaf1983cb7c0b2bba294c807f31b7b4.pdf- The Iranian Society of Pharmacognosy

Several species of this genus are perfumed and wealthy in essential oils. Some of them are used in industry, pharmacy and aromatherapy. They have shown different biological effects such as antibacterial and antioxidant activity. For the present study, <em>Salvia verticillata </em>L. was collected from Shahrestanak, Mazandaran, Iran. Hydrodistilled essential oil from the aerial parts of this plant was obtained with a Clevenger type apparatus and was analyzed by GC and GC/MS. Moreover, the cytotoxic activity of the essential oil was investigated against HT-29 (colon adenocarcinoma), Caco-2 (colorectal adenocarcinoma), T-47D (breast ductal carcinoma) and NIH-3T3 (Swiss mouse embryo fibroblast) cell lines by MTT test. 59 components were characterized from the oil with <em>trans</em>-caryophyllene (24.40%), β-phellandrene (9.08%), α-humulene (8.61%), bicyclogermacrene (6.32%), spathulenol (5.89%) and β-pinene (5.00%) as the major constituents. These compounds represented 97.67% of the essential oil and included monoterpenes (34.83%) and sesquiterpens (61.84%). The results of the cytotoxicity assay demonstrated that the essential oil of <em>S. verticillata</em> showed higher cytotoxic effect on Caco-2 cell line.https://www.rjpharmacognosy.ir/article_5775_57b33c5f440c03ea7ca26a0d3488d251.pdf- The Iranian Society of Pharmacognosy

ShahrestaniTraditional Medicine and Materia Medica Research Center and Department of Traditional Pharmacy, School of Traditional Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.M. ShekarchiFood and Drug Control Laboratories and Food and Drug Laboratory Research Center, MOH & ME, Tehran, Iran.Journal Article20141229Phenolic and flavonoid compounds are secondary metabolites of plants which possess various activities such as anti-inflammatory, analgesic, anti-diabetes and anticancer effects. It has been established that these compounds can scavenge free radicals produced in the body. Because of this ability, not only the plants containing phenolic and flavonoid compounds but also, the pure compounds are used in medicinal products for prevention and treatment of many disorders. Considering that the golden aim of the pharmaceutical industries is using the most effective compounds with lower concentrations, determination of the best combination of the compounds with synergistic effects is important. In the present study, synergistic antioxidant effects of four phenolic compounds including caffeic acid, gallic acid, rosmarinic acid, chlorogenic acid and two flavonoids, rutin and quercetin, have been investigated by FRAP (Ferric Reducing Antioxidant Power) method. The synergistic effect was assessed by comparing the experimental antioxidant activity of the mixtures with calculated theoretical values and the interactions of the compounds were determined. The results showed that combination of gallic acid and caffeic acid demonstrated considerable synergistic effects (137.8%) while other combinations were less potent. Among examined substances, rutin was the only one which had no effect on the other compounds. The results of ternary combinations of compounds demonstrated antagonistic effects in some cases. This was more considerable in mixture of rutin, caffeic acid, rosmarinic acid (-21.8%), chlorogenic acid, caffeic acid, rosmarinic acid (-20%), rutin, rosmarinic acid, gallic acid (-18.5%) and rutin, chlorogenic acid, caffeic acid (-15.8%), while, combination of quercetin, gallic acid, caffeic acid (59.4%) and quercetin, gallic acid, rutin (55.2%) showed the most synergistic effects. It was concluded that binary and ternary combination of quercetin, rutin, caffeic acid, chlorogenic acid, gallic acid and rosmarinic acid could influence the antioxidant ability; therefore, to obtain the best antioxidant effects in products containing these materials, the interactions should be mentioned.https://www.rjpharmacognosy.ir/article_5776_2f1608bf9318a09e55c6c82494f8067e.pdf- The Iranian Society of Pharmacognosy

Evaluating the biological activity of these materials could become possible with the aid of cosolvents/surfactants which obviously should have little or no cytotoxic activity. In the present study, the cytotoxic activity of six cosolvents/surfactants: ethanol, methanol, Tween 20 and 80, propylene glycol (PG) and poly ethylene glycol 400 (PEG) which are usually helpful in dissolving non-soluble herbal extracts, has been evaluated against HepG-2, MCF-7 and HT-29 cells by MTT assay. Among the investigated cosolvents/surfactants, Tween 20 and 80 demonstrated the highest and ethanol and methanol the lowest cytotoxicity to the evaluated cell lines, suggesting the two latter as proper aids for improving solubility in biological experiments.https://www.rjpharmacognosy.ir/article_5777_9dc5c5256a5d2af01f9cf25200e897e9.pdf- The Iranian Society of Pharmacognosy
