Study on the antioxidant activity of tea flowers (Camellia sinensis).
Major chemical compounds in different extracts from tea flowers (Camellia sinensis) were analyzed. Distilled water or 70% ethanol extracts were then fractionated with chloroform, ethyl acetate and n-butanol, respectively. Each extract fraction was tested its scavenging activities on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl free radicals. The results showed that ethyl acetate fraction o...
متن کاملMetabolomics analysis reveals the compositional differences of shade grown tea (Camellia sinensis L.).
The different cultivation methods affect tea quality by altering the basic metabolite profiles. In this study, the metabolome changes were investigated in green tea and shade cultured green tea (tencha) by liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) coupled with a multivariate data set. The principal component analysis (PCA) and orthogonal pr...
متن کاملStudy on lead levels in infusion time of imported green and black tea (Camellia sinensis L)
Background: Nowadays, tea is the most popular and frequently consumed beverages in the world after water. There are some beneficial trace elements in tea such as fluoride, caffeine and essential minerals, although there may be heavy metals in tea leaves which threat seriously human health. Therefore, the main objective of current study was to determine and monitor lead content in imported black...
متن کاملExpression of caffeine biosynthesis genes in tea (Camellia sinensis).
Using semi-quantitative reverse transcription-PCR, we studied the expression of genes encoding caffeine synthase (TCS1), inosine-5'-monophosphate dehydrogenase (TIDH), S-adenosyl-L-methionine synthase (sAMS), phenylalanine ammonia-lyase (PAL) and alpha-tubulin (Tua1) in young and mature leaves, stems and roots of 4-month-old tea seedlings and young and old tea tissue cultures. The amounts of tr...
متن کاملCharacterization of Armillaria isolates from tea (Camellia sinensis) in Kenya.
Armillaria is a primary root rot pathogen of tea (Camellia sinensis) in Kenya. The main species presently described in this country are A. mellea and A. heimii. A survey covering fourteen districts of Kenya was carried out and forty-seven isolates of Armillaria collected. Cultural morphology, rhizomorph characteristics, somatic incompatibility and features of basidiomata were used to characteri...
