“…26 In this method, DPPH solution (0.004% w/v, 0.1 mM) was prepared in methanol, 0.1 mL of sample solution was added to 3.9 mL of DPPH solution and then incubated at room temperature for 30 min, the absorbance was read at 517 nm and the experiment was carried out in triplicate. 27 Methanol was used as blank, ascorbic acid and BHT as positive controls. The percentage of radical scavenging activity was calculated from Equation (1):…”

A B S T R A C TBackground: The genus of Stachys with 300 species belongs to Lamiaceae family and this genus has 34 species in Iran. Stachys turcomanica Trautv is native to Iran and it used for treatment of infectious, rheumatic and inflammatory diseases in traditional medicine. The effect of solvent (methanol in water: 0, 20, 50, 80 and 100 %) on the extraction of antioxidant compounds from S. turcomanica were investigated using various in vitro assays. Methods: The antioxidant activities of extracts were studied via three methods: FRAP (ferric reducing antioxidant power), DPPH (2, 2-diphenyl-1picrylhydrazyl) and beta-carotene linoleic acid bleaching. Results:The results of present work revealed that the solvent combinations have effects on the extraction of phenolic compounds and antioxidant properties. The relative methanol/water ratio of 80:20 v/v was effective solvent in the extracting of phenolic compounds. Also, there was a good correlation between antioxidant activity and total phenolic content S. turcomanica extracts. Conclusion:The results demonstrated methanol/water (80:20) ratio was the best solvent to release of many secondary metabolites from S. turcomanica for future studies, which could provide natural sources of antioxidant compounds.

Background: Ultrasonic extraction is one method for optimization of effective compounds from plants. Objectives: The aim of this study was optimization of the extraction conditions of Myristica fragrans seeds using ethanol as a food grade solvent and by ultrasonic-assisted extraction using response surface method (RSM). Methods: Ultrasonic-assisted extraction was used for extraction of M. fragrans seeds. Response surface methodology (RSM) was used to optimize three parameters: time and of temperature extraction (min,°C), and solvent to material ratio. Antioxidant activity and phenolic contents were determined. Results: The results showed that optimal ultrasonic-assisted extraction (UAE) conditions were 29.57 minutes extraction time, 374.61 mL/g ratio of solvent to material and 41.89ºC extraction temperatures. The yield of extraction, amount of total phenolic content, IC50 (in DPPH method) and FRAP in M. fragrans seeds in optimum conditions were 18.14%, 63.41 mg gallic acid/g of extract, 43.66 mg/mL and 99.38 mmol/g of extract, respectively. Conclusions: The results indicated of the ultrasonic-assisted extraction having power for optimization of the extraction condition and it is appropriate for extraction of antioxidant and phenolic compounds.

Scutellaria (Lamiaceae), which contains over 350 species, usually known as skullcaps, is found throughout Europe, the United States, and East Asia. In traditional Chinese medicine, several species are used to wipe out heat-evil and remove surface ills (TCM). The current study examines the ethnopharmacology, biological activity, and chemical substances associated with Scutellaria species. More than 295 chemicals, including flavonoids and diterpenes, have been identified. Scutellaria and its active principles have been shown in studies to have a wide range of pharmacological activities, including antioxidant, antimicrobial, antifeedant, phytotoxic, acaricidal toxicity, antibacterial, anti-inflammatory, and antianalgesic activities. Currently, effective monomeric compounds or active components from Scutellaria have been evaluated for pharmacological action in vivo and in vitro. More data facilitates applications and exploitation of novel medication development.
