Identification of coffee leaves using FT-NIR spectroscopy and SIMCA [PDF]
Talanta, 2018 Abundant 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.

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.

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 ...

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.
