The effects of water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower on serum lipid concentrations were evaluated in rats. Forty-eight male Sprague-Dawley rats weighing l00±l0 g were divided into six groups and fed high fat diets for six weeks. Experimental groups were administered with following diets; Control diet, animal, plant high fat diet and control and high fat diets with 2% water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower. Tissue weights of liver, lung, stomach, heart, kidney and spleen of high fat diet exposed rats were reduced by water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups. The concentrations of serum triglyceride in rats fed the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower were lower than those in other groups. The concentrations of total cholesterol in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower group were lower than those in high fat diet groups. The concentrations of HDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were significantly higher than those of other groups. The levels of LDL-cholesterol in serum of the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups were tended to be lower than those of other groups. GPT and GOT activities were decreased in water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups and than in the high fat group. LDH activity was lower in the water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups than in the high fat group. These results suggest that water extracts of green tea scented with lotus Nelumbo nucifera Gaertner flower groups may reduce elevated levels of serum lipid concentrations in rats fed high fat diets.

The objective of this study is to propose an export strategy due to an analysis of USA and Japan consumer's perception and willingness-to-pay for flower tea. For that, we conducted a survey on the consumer's perception on flower tea compared with leaf tea such as green tea. We also analyzed the willingness to purchase and pay for it. The reasons of drinking of flower tea for USA consumer are 'flavor'-followed by 'taste', and for Japanese consumer 'relaxation'-followed by 'flavor' in order. Both of them consider 'quality', 'safety'- and 'origin' in order when they purchase flower tea. USA consumers have a willingness-to-pay of about 8.3% and Japanese consumers have a willingness-to-pay of about 29.1%. Based on those results, it is necessary to differentiate the process and marketing strategies for the export of flower tea.

The present study has been undertaken to characterize availability of camellia(Camellia japonica L.) as a medicinal plant with antineoplastic and chemosensitizing activities. The crude extracts from fresn camellia flower, young leaves and nutraceutical tea of camellia leaf and flower buds were evaluated on their potential activities against various human cancer cells and multidrug resistance to cancer cells in vitro. The range of cytotoxicity displayed from 120$\mu\textrm{g}$/mL to 200$\mu\textrm{g}$/mL. Catemix 1(CT-1) mixed with camellia and green tea showed high toxicity(respectively IC$\sub$50/=l16$\mu\textrm{g}$/mL, 129$\mu\textrm{g}$/mL) against AML-2/WT, acute myelogenous leukemia cell and MCF-7, brest adenocarcinoma pleual effusion cell. Generally camellia tea mixed with green tea showed higher cytotoxicity than the other camellia teas mixed with some herbs(CH). Methanol extract of steamed camellia tea and roasted camellia tea had a chemosensitizing effect to reverse Pgp-mediated MDR. In addition, camellia flower tea of insignificant cytotoxicity, chemosensitizing effect were increased remarkably chemosensitizing effect in mixed flower tea with some herbs.

Most of leaf teas, except flower tea, were considered as good materials with basic conditions for tea manufacture because water content was below 6 %, Crude protein was the greatest component in roasted young leaf tea, crude fats in roasted mature leaf tea and ashes in fermented young leaf tea. Caffein were present as the highest amount(5.18%) in steamed mature leaf tea, showing less amount than greenp teas. Catechin were contained as the highest amount in all kinds of teas, especially fermented young leaf tea. was the highest(9.57%). Tannin, which highly related with tea quality including astringent taste, color and perfume, were present as the highest amount in fermented young leaf tea.(중략)

The objective of this study is to propose the motivation of the analysis on consumer's purchase behavior and willingness-to-pay for flower tea. Therefore, we survey the purchase behaviors on flower teas as compared with leaf teas such as green teas. We also analyze the willingness to purchase and pay for such teas. The reasons for consuming flower teas are 'flavor', 'beauty/diet', 'health', consecutively. Consumers prioritize 'safety', 'quality', 'price', and 'design' when purchasing flower teas. Nevertheless, it is also essential to consider 'flavor' as a quality factor. It is necessary to differentiate the process and marketing strategies for the development of flower teas.

In this study, to develop balloon flower (Platycodon grandiflorum) leaves, which are not used as tea, a method of making green tea was referred to, and several physiological activities were analyzed using the balloon flower leaf tea with different times of roasting and rubbing. The highest total polyphenol and tannin contents were 33.02 mg GAE/g and 5.03 mg/g at two times of roasting and one time of rubbing, respectively. In the case of the total flavonoids, the RO3 + RU2, subjected to three times of roasting and two times of rubbing, showed the highest value, whereas there was no significant difference between the control and the other samples. Except for the green tea as a control, the RO2 + RU1 samples reported the highest antioxidant activity whereas it decreased with increasing number of times of roasting and rubbing. The color, lightness, and yellowness tended to decrease slightly as the number of increasing roasting and rubbing among the samples with no significant difference. All of these things together, to develop tea using the balloon flower leaves would be suitable with two times of roasting and one time of rubbing.
