An efficient protocol was developed to control excessive phenolic compound secretion during callus culture of cotton. As cotton is naturally rich in phenolic compounds factors influencing the phenolic compound secretion, callus induction and proliferation were optimized for getting high frequency callus culture. Different carbon sources such as fructose, glucose, sucrose and maltose were tested...

Studies have demonstrated that phenolic compounds andcarotenoids are essential for prevention of diseases. On the other hand, endogenous ethylene enhances the ripening of fruits and stimulatesthe biosynthesis of carotenoids as well as chlorophylls destruction. The aim of this study was to evaluate the effect of rootstocks on phenolic compounds andcarotenoids. The contents of individual phenolic...

a pot experiment was conducted to evaluate the extract biochemical variations among 25 spearmint population. the experiment was a randomized complete design (rcd) with 25 treatments (population) and three replications. for this purpose, three rhizomes with 5 cm length were selected and planted in each pot. all pots were kept out side. the plant samples of all treatments were harvested at full f...

In this study, phenolic content of Pinus brutia’s bark was examined using an ultra-performance liquid chromatography tandem mass spectrometry with electrospray ionization source (UPLC-ESI-MS/MS) working in multiple reaction monitoring mode. Ultrasonic extraction method with 50% ethanol solution was used for the extraction of bark. The bark of Pinus brutia consisted of 15 compounds: gallic acid,...

background kelussia odoratissima mozaff. is one of the newest genera of umbelliferae which is represented by only one species. this sweet-smelling, self-growing monotypic medicinal plant is endemic to a restricted area in west of iran and is locally called karafse-koohi. the aerial parts of the plant are commonly used as a popular garnish and a sedative medicinal plant. there are several report...

OBJECTIVES Sweet peppers Capsicum annuum L. (C. annuum) are an excellent source of vitamins A and C as well as phenolic compounds, which are important antioxidant components that may reduce the risk of diseases. The objective of this study was to evaluate their antioxidant activity under various temperatures. MATERIALS AND METHODS To compare the antioxidant activity in various temperatures (2...

Aloe vera gel is widely used as a functional ingredient in food processing. This gel is very unstable due to its high water activity. Drying process can be used to obtain shelf stable products. Response surface methodology was used to assess the effects of solution concentration (30-60% w/w), solution temperature (30-50°C) and immersion time (4-6h) at atmospheric pressure and constant solution ...

Object-space model optimization (OSMO) has been proven to be a simple and high-accuracy approach for additive manufacturing of tomographic reconstructions compared with other approaches. In this paper, an improved OSMO algorithm is proposed in the context OSMO. addition two steps each iteration OSMO, another are introduced: one step enhances target regions’ in-part edges intermediate model, wea...

The essential oil of Pimenta dioica was isolated by hydro distillation and steam distillation. The aqueous extract was also taken. The antioxidant, total phenolic and the antimicrobial studies were conducted. The antimicrobial activity was significant. The IC50 value of extract and essential oil are 390 μg/ml and 2340 μg/ml respectively.
