cup of tea was brewed by the emperor Shen Nung. He was the second emperor of China and is known to have invented agriculture‚ the plow‚ and discovery of medicinal herbs. Tea was accidently discovered when Shen Nung was carrying wild tea brush to use as firewood when a gust of wind blew some tea leaves into his pot of boiling water. He found the mixture a delicate and refreshing drink. Tea evolved into an everyday drink in China. The Chinese used tea to heal the sick and to quench thirst. Tea was also

INTRODUCTION: Lipton was created at the end of the 19th century by Sir Thomas Lipton. Under the slogan “Direct from the tea gardens to the tea pot” this entrepreneurial businessman wanted to make tea a popular and approachable drink for everyone - with a high quality but reasonably priced product. The Lipton business was acquired by consumer goods company Unilever in a number of separate transactions‚ starting with the purchase of the US and Canadian Lipton business in 1938 and completed in 1972

Extraction of Caffeine from Tea Leaves Department of Biological Sciences‚ College of Science University of Santo Tomas España‚ Manila‚ 1028 ABSTRACT: Caffeine is a white crystalline xanthine alkaloid that acts as a stimulant drug. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants. It is most commonly consumed by humans in infusions extracted from the seed of the coffee plant and the leaves of the tea bush‚ as well as from various foods and drinks containing

This drug is found in a number of things ingested by people. It belongs to a group of nitrogen bases called purines. Because caffeine possesses these base-like properties‚ it is described as an alkaloid. They usually taste bitter and often are physiologically

Differed ways to consume tea resulted in different ways of using tea wares. Compared to the typical way of tea drinking in the late-Ming period‚ the process of tea-tasting in the Tang and Song dynasties were much more complicated. The complication implied that tea connoisseurs in the Ming era had drastically simplified the tea vessels they often used‚ as well as the whole procedure of tea tasting. The understandings of Tang-style tea drinking have been significantly transformed by the re-apparition

In this lab‚ caffeine was extracted from black tea‚ and green tea through a vacuum filtration‚ and a rotovap. The melting point of the sample of black tea was 219.12-236.05 ˚c‚ and for the green tea it was 176.22-227.6 ˚c. The % error of the melting point indicates how much error there was from the melting point taken experimentally. The % error of the melting point for black tea was 0.44%‚ and for green tea it is 3.15%.Since the theoretical melting point of caffeine is between 235-237 ˚c‚ we can

Abstract This work describes the extraction of caffeine from tea leaves to determine its % caffeine. The extraction process selectively dissolves one or more compounds in a mixture into an appropriate solvent. In this experiment‚ it was visible in the process wherein the components of the tea leaves were dissolved in two solvents‚ water and dichloromethane (DCM)‚ with DCM used for multiple extractions. The organic layer was evaporated and the determined % caffeine was 0.12%. Furthermore‚ the purified
