In order to determine the free radical scavenging power of Camellia varieties by DPPH and ABTS, five different solvents were used at 50 mg/ml concentration. The better results were found in ethanol, methanol and DMSO extracts as compared to chloroform and pet ether extracts. Both DPPH and ABTS showed similar results (Figure 1).
In current research two tea varieties such as China tea plant (Camellia sinensis) and Assam tea plant (Camellia assamica) were used. China tea plant is a big shrub with hard, thick and leathery leaves; and generally flowers white sometimes with pink pigmentation. Whereas Assam tea plant is a small tree with thin and glossy leaves; and white flowers, occasionally with pale yellow pigmentation. It has been shown that C. sinensis cultivated in China, Japan and Turkish whereas C. assamica cultivated in Indonechia and Sri lanka, respectively. P3 clone is the hybrid of Chinese tea varieties. Green tea is currently considered a source of dietary constituents capable with biological and pharmacological activities for human health. The extracts prepared from leaves to be used as medicine. The present study provides the information on the antibacterial and antioxidant importance of green tea varieties. Many therapeutic values of green tea has been explored including lowering body temperature, blood purification, aiding digestion, strengthening teeth and boons, boost immune system, suppress aging, lower the blood sugar levels and enhance the heart functions[22].
Essential and non essential trace metals in fruits and vegetables may decrease the chronic diseases such as cancer and cardiovascular diseases [23]. The higher concentrations of potassium, sodium, magnesium and calcium were found in the dry leaves of C. sin...

...ram-negative bacteria. Antibacterial, antifungal and antioxidant activities of green tea have also been reported [31, 32]. Ethanol, methanol and DMSO extracts of green tea varieties showed the inhibition of all tested bacteria. These extracts have chemical compounds which are responsible for the inhibition of S. aureus, S. epidermidis, K. pneumonia, S. marcescens, S. pyogene and P. aeruginosa. Turkmen et al. [32] reported the antibacterial, antioxidant and phytochemical screening of black tea.
Data presented in this study revealed potential in vitro antibacterial and antioxidant activities of Camellia varieties having both essential and non essential trace metals, and bioactive compounds. Further studies may require optimizing the extraction of bioactive compounds from green plants, chemical portrayal of such compounds and further testing of their effects in vivo.
This year, I learned a lot in College Writing 112. This class is different from any other classes. You cannot learn to write by only going to class and listening to the lectures. It is something that you can only learn it by yourself; the professors can only guide you through the difficulties. The only way to improve writing is to practice. The more you write, the better you will become. Once you learn it, it will become part of you—you will never forget writing.
Phenolic acids are secondary plant metabolites widely distributed in foods, especially fruits and vegetables. In recent years, phenolic acids have attracted a lot of attention because they exist ubiquitously in plants and play protective roles. Phenolic acids possess interesting biological properties, (Beilin, Stocker, & Croft, 1997) that render them interesting to study. They are widespread in crops such as fruits, vegetables, herbs, grains, and seeds and derived foods such as juices, wines, and oils, (Graf, Ameho, Dolnokowski, Milbuty, Chen, & Blumberg, 2006). Phenolic compounds play a key role in thwarting the negative impacts of oxygen and nitrogen reactive species (ROS/RNS), maintaining the redox homeostasis of biological fluids and preventing conditions such as cardiovascular diseases, atherosclerosis, and other degenerative pathologies, such as cancer, diabetes, Alzheimer’s and Parkinson’s diseases, (Shahrzad & Bitsch, 1998).
Microbial pigments have antioxidant activity because of their biological functions.and these pigments are Carotenoid ,naphthaquinone,and Violacein.
Green tea is known as one of the highest polyphenols, an antioxidant that has an anti inflammatory effect and can help in rheumatoid arthritis prevention. These anti inflammatory chemicals can also be found in decaffeinated green tea, so it can be an option if you d...

Although chemotherapy is an effective treatment for cancer, patients still suffer from side effects such as hair loss. Thus, more studies need to be done to find alternative medications that do not have side effects. Folk medicine is one option used to treat many diseases such as hepatitis B, bacterial infection and parasitic infection (Ahmad et al., 2013). For instance, black seeds (black cumin) showed effects on cardiovascular disease because of the presence of the Thymoquinone component (Ahmad et al., 2013, Khan et al., 2011). Thymoquinone (TQ) has anti-inflammatory, anti-bacterial and anti-cancer properties (Ahmad et al., 2013). Therefore, black seeds limit the replication of the abnormal WBCs that contain the leukemia. In previous studies, derivatives of black seeds were used against myeloid leukemia (Khan et al., 2011), but this study is focusing on the effects of black seeds themselves.
The major catechins found in tea are EGCG, EGC, ECG, and EC. Previous studies have shown that they inhibit expressions of carcinogen activating enzymes and increase enzyme levels that detoxify carcinogens. In addition, studies have shown that tea polyphenols inhibit carcinogen-induced DNA damage in some cell lines. Other studies have shown that tea constituents inhibit cancer development and reduce the risk in animal models of stomach, colon, liver, skin, breast, and prostate cancer. In a study, extracts from tea exhibited a dose-dependent protection of Chang liver cells. In a co-treatment consisting of EGCG and bleomycin there was 50% decrease in comparison to the treatment of bleomycin alone. (Yang, et al,
This study is based on trends observed in terms of changing Indian people lifestyles, improving health and awareness and consumers of tea. It looks like lately when you go to the convenience store or grocery store, you can see displays which are offering green tea beverages. Even though green tea has been used for years and years, but it seems as if there is a recent push for persons to start drinking green tea, but why? The fact is that nutritionists are started to notice it known to the public that green tea has some healing properties that we cannot be ignored. We are a health conscious people and nation, and green tea contributes greatly toward a person’s health and can promote healing for certain pretty serious diseases.
Epigallocatechin-3-gallate (EGCG) is the most abundant and most biologically active catechin found in green tea. It is believed that EGCG possesses much of the health promoting properties of green tea, including anti-inflammatory, immunomodulatory and antioxidant effects. In 1999, Haqqi and colleagues first reported the disease modulating effects of green tea polyphenols (GTPs) on RA in a murine collagen-induced arthritis (CIA) model. They found the GTPs administration would significantly reduce the incidence and lower the disease severity of arthritis, associated with a marked reduction in the expression of IFN-γ, TNF-α, and cyclooxygenase(COX)-2, as well as total IgG and type II collagen-specific IgG (Ab) in arthritic joints. Later on, the therapeutic effects of green tea or EGCG have been consistently reported in series of experiments using either CIA or Adjuvant-induced arthritis (AIA) disease models. Interestingly, in a prospective cohort study with 31,336 subjects, Mikuls et al. reported that consuming tea >3 cups per day could significantly reduce the risk of RA

So from last many thousands years the medicinal plant being used by humans for different therapeutic purpose and are changed to modern medicine like many modern drugs originated from plant source. Many of the life saving drug are isolated/extract from medicinal plant examples include Vincristine (Vinca), digoxin (Digitalis), quinine (cinchona bark), Atropine (Datura), Artimicine (Artimisia annua), morphine (from the opium poppy) (Vickers and Zollman, 1999). As per WHO the uses of herbal drug was increased day by day to two- three time more as compared to conventional drug in different form like nutraceuticals, ayurvedic drugs, traditional chinse medicine, Functional food etc (Evans, 1994).
Green tea is made from the plant Camellia Sinensis’s leaves without fermentation (Suzuki, Miyoshi & Isemura, 2012) and is regarded as a popular and healthy drink in Asian countries because of its health-promoting potentials such as protecting against cancer and cardiovascular disease (Harvard Health Publications, 2012; Iwasaki et al., 2014). Lots of the positive effects are due to the antioxidative activity of (-)-epigallocatechin gallate (EGCG) which is a major component of green tea (Suzuki et al., 2012). And it draws researchers’ interests and attentions to further investigate. According to Suzuki et al., one example of the health advantages is that catechins in green tea bring an anti-obesity effect by stimulating lipid metabolism in liver (2012).
Herbal remedies’ qualities are widespread availability, lower cost, effective for chronic conditions. Herbal remedies are the use of plants or plant extract to treat a person’ overall health. Herbal treatments are prominent for developing countries for instance, “in Africa up to 90% and in India 70% of the population depend on traditional medicine to help meet their health care needs” (Wachtel-Galor & Benzie, 2011), due to their low cost and availability. Herbal remedies have gained attention in the past decades, and expanding their uses due to the increased interest of natural therapies (Wachtel-Galor & Benzie, 2011). Herbs used on the remedies grow in the wild throughout the world, therefore making it easy to
