Arrabidaea chica (Humb. & Bompl.) Verl. is an herb popularly used in the treatment of anemia in the Brazilian Amazon region, and little is known about its mineral content. Therefore, the elemental contents of Cu, Fe, Mn, and Zn were determined in the dried leaves and tea obtained by decoction and infusion of the three varieties of the medicinal plant using flame atomic absorption spectrometry after acid wet digestion of the samples. In general, the levels of the minerals are in good agreement with other studies involving medicinal plants, and the variety AC2 had the highest concentrations of all elements both in dried leaves and tea. Iron was found to be the most abundant in dried leaves (38.4-115.5 μg g(-1)), whereas manganese had the highest extraction efficiencies both in decoction (56.1-62.7%) and infusion (45.6-63.6%). Additionally, the decoction was more efficient in the extraction of almost all elements. The consumption of the decoction of variety AC2 may contribute to a small proportion to the daily requirements of Mn.

Foliar calcium application reduces fluorine accumulation in tea plant by regulating cell wall structure and gene expression.
Front Plant Sci
January 2025
Xinyang Agriculture and Forestry University, Henan Key Laboratory of Tea Plant Comprehensive Utilization in South Henan, Xinyang, Henan, China.
Tea plant can enrich a large amount of fluorine (F) in the cell wall of its mature leaves, thus posing the risk of excessive intake of F for tea consumers. This study investigated the effect of foliar calcium (Ca) application (0.05-1 mM) on F accumulation in tea plant leaves by analyzing the association of F with cell wall materials, pectin methylesterification structure, and cell wall genes.

The mycotoxin tenuazonic acid (TeA) inhibits photosynthesis and is expected to be developed as a bioherbicide to control Ageratina adenophora that is one of the most serious invasive alien plants in China. New leaves sprouting from A. adenophora at low temperatures (LT) in early spring are less sensitive to TeA compared to those growing in summer.

Background: Today, customers pay more attention to the feed composition and carcasses of poultry, and the interest in using natural and safe compounds such as medicinal plants and their extracts in animal feed is increasing.
Objectives: The present experiment was conducted to assess the effect of green tea (Camellia sinensis) and mulberry (Morus alba) leaves powder on the meat quality, intestinal microbiology and serum biochemical parameters in broilers.
Methods: The experiment was conducted with 648 one-day-old Ross 308 broiler male chicks with a factorial arrangement including three levels of green tea powder (GTP) and three levels of mulberry leaf powder (MLP), with nine treatments and six replications in a completely randomized design for 42 days.
Dynamics of linalool and its derivatives enantiomers in var. "Hainan dayezhong".
Food Chem X

Hainan Institute, Zhejiang University, Sanya 572025, China.
We here analyzed changes in the proportion and content of chiral isomers of linalool and its derivatives in "Hainan dayezhong" throughout its life cycle from tea tree growth and tea manufacturing to brewing. The chiral isomers of aromatic compounds present in fresh tea leaves were found to undergo substantial diurnal and seasonal changes during tea tree growth, and their proportions varied slightly across different leaf positions. The chiral isomer content of linalool and its derivatives was consistently higher in stems than in leaves.
