In this study, ultrasound-assisted extraction (UAE) and other methods of extracting flavonoid compounds and ferulic acid (FA) from S. sinensis were investigated. Five different extraction methods, including water extraction (W), water extraction using UAE (W+U), 75% ethanol extraction (E), 75% ethanol extraction using UAE (E+U), and supercritical CO2 extraction (SFE) were applied in the extract...

Extracts of Camellia sinensis Linn. leaves, Glycyrrhiza glabra Linn. roots and rhizome and Calendula officinalis Linn. flowers were screened for their in vitro antimicrobial activity using agar disc diffusion method. The antimicrobial activity of petroleum ether, dichloromethane and methanolic extracts of different parts of these plants were studied against acne causing bacteria, namely Staphyl...

Relaxation force properties of single sea buckthorn berries under uni-axial compression were studied. Sea buckthorn berries had a time dependent behavior similar to other viscoelastic materials. The three-term Maxwell model with a maximum relative difference (MRD) of % 5 ≤ was chosen as the best fit equation to the relaxation data. For both Indian Summer and Sinensis cultivars, the firmness (as...

This paper reviews the epidemiological status and characteristics of clonorchiasis at global level and the etiological relationship between Clonorchis sinensis infection and cholangiocarcinoma (CCA). A conservative estimation was made that 15 million people were infected in the world in 2004, of which over 85% distributed in China. The epidemiology of clonorchiasis is characterized by rising tr...

Antllocyanin-rich crops have attracted attention in recent years because of their health benefits, and anthocyanin-rich tea is one of these crops. 'F95181' (Camellia sinensis) was developed for breeding anthosyanin-rich tea cultivars and registered as a new parental line 'Cha Chuukanbohon Nou 6' (C. sinensis) in 2004. 'F95181' was selected from an interspecific cross betweell C. taliensis (a wi...

Characteristic secondary metabolites, including flavonoids, theanine and caffeine, are important components of Camellia sinensis, and their biosynthesis has attracted widespread interest. Previous studies on the biosynthesis of these major secondary metabolites using next-generation sequencing technologies limited the accurately prediction of full-length (FL) splice isoforms. Herein, we applied...

A 35% EtOH extract of the fruits of Chaenomeles sinensis, long utilized as a folk medicine for cough, significantly inhibited the pruritogenic agent compound 48/80 (COM)-induced scratching behavior in mice. Antipruritic activity-guided fractionation and purification yielded active quercetin, apigenin, and catechin derivatives, which exhibited significant inhibitory effects on COM-induced scratc...

In vitro cell proliferation, cell cycle arrest and induction of apoptosis were investigated, using three human head and neck squamous cell carcinoma (HNSCC) cell lines (OSCC-3, SCC-61, and SQ-20B). Aqueous extracts of Camellia sinensis, Ilex paraguariensis, and Ardisia compressa were tested and (-) epigallocatechin-3-gallate (EGCG) was used for comparison. For EGCG the IC50 values were between ...

There have been efforts to overcome the problem in treatment of cancer using medicinal plants. It has been shown that Citrus essential oil of contains different terpens with antitumor activities. In this study we sought to determine the cytotoxicity of essential oils of Iranian Citrus limon (L.), C. medica (L.), C. sinsensis (L.) peels on cancer cell lines. Essential oils were prepared by hydr...

The present study appraised the hepatoprotective activity of aqueous extract of Camellia sinensis leaves and its possible mechanism of action against carbon-tetrachloride-induced liver damage. Liver damage was induced by   intraperitoneal administration of equal mixture of carbon tetrachloride   and olive oil (50 % v/v, 0.5 ml/kg ) in male Wistar rats (150-220g) once daily for...
