Composition of cutin from coffee leaves
Phytochemistry, 1972Abstract The constituents of the cutin of coffee leaves have been identified using TLC, GLC and GLC-MS. Dihydroxyhexadecanoic acids comprise more than 60% of the total acids. Other compounds identified include C 16 -C 34 monobasic acids, C 14 and C 15 monohydroxymonobasic acids, 16-hydroxyhexadecanoic acid and monohydroxyhexadecane-1,16-dioic ...

Permanence of Free Water on Coffee Leaves
Experimental Agriculture, 1987SummaryThe presence of free water on both surfaces of the leaves of shaded and unshaded coffee trees was evaluated at Cenicafé, Colombia. Rainfall was the main source of humidity and dew was not registered during the experiment. Five mm of rain caused canopy saturation and water began to reach the underside of the leaves. The period of wetness lasted 9.

Beneficial compounds from coffee leaves
2018Leaves are the leading source of carbon for plant growth and reproduction, and possess a wide range of protection systems against environmental stress. The leaves of the coffee plant, characterized by a high antioxidant potential, have a significant impact on fruit quality, and identifying markers in leaves for plant adaptability to environmental ...

Fungal Epiphytes and Endophytes of Coffee Leaves (Coffea arabica)
Microbial Ecology, 2005Plants harbor diverse communities of fungi and other microorganisms. Fungi are known to occur both on plant surfaces (epiphytes) and inside plant tissues (endophytes), but the two communities have rarely been compared. We compared epiphytic and endophytic fungal communities associated with leaves of coffee (Coffea arabica) in Puerto Rico.

Phytochemistry, 2006
In plants, PPO has been related to defense mechanism against pathogens and insects and this role was investigated in coffee trees regarding resistance against a leaf miner and coffee leaf rust disease. PPO activity was evaluated in different genotypes and in relation to methyl-jasmonate (Meja) treatment and mechanical damage.

INFLUENCE DISEASE SPOTS LEAVES ON COFFEE PLANTS AND THEIR CONTROL
Journal of Agriculture, 2022The disease spotting leaf is one disease in coffee plants caused by mold Cercospora caffeicola, also known as brown eyespot. Disease spotting leaf could attack part leaf coffee plant and the fruit (Harni et al., 2015) . The disease this can attack coffee plants during the seedling period until with plant ripens.

Identification of coffee leaves using FT-NIR spectroscopy and SIMCA
Talanta, 2018Abundant literature has been devoted to coffee beans (green or roasted) chemical description but relatively few studies have been devoted to coffee leaves. Given the fact that coffee leaves are used for food and medicinal consumption, it was of interest to develop a rapid screening method in order to identify coffee leaves taxa.

Quantification of cercosporin from coffee leaves infected by Cercospora coffeicola
Australasian Plant Pathology, 2022Cercosporin, a nonspecific toxin produced by Cercospora spp., Pseudocercosporella spp. and Colletotrichum spp., is a photosensitizing compound that rapidly kills plant cells in the presence of light. Although this toxin is a virulence factor, its quantification in coffee leaves has not previously been reported.
