Potential beverage quality of three wild coffee species (Coffea brevipes, C. congensis and C. stenophylla) and consideration of their agronomic use

Journal of the Science of Food and Agriculture, Volume 103, Issue 7, Page 3602-3612, May 2023., 2023
Abstract BACKGROUND Of the 130 known coffee (Coffea) species, very few have been properly evaluated for their beverage quality. The diversity of wild coffee species is considered critical to the long‐term sustainability of the coffee sector, particularly under climate change.

Comparison of chemical compositions, antioxidant activities, and acetylcholinesterase inhibitory activities between coffee flowers and leaves as potential novel foods

Food Science &Nutrition, Volume 11, Issue 2, Page 917-929, February 2023., 2023
The chemical compositions of coffee flowers and leaves Arabic Coffea from Yunnan province, China were compared with green coffee beans by HPLC–MS and GC–MS. Antioxidant and acetylcholinesterase inhibitory activities were higher than green coffee beans in vitro. Thirty differentially changed chemical compositions were confirmed.

Intraspecific variation in growth response to drought stress across geographic locations and genetic groups in Coffea canephora

Ecology and Evolution, Volume 13, Issue 1, January 2023., 2023
Drought tolerance within C. canephora is negatively linked to growth. Drought tolerance of Uganda's C. canephora is weakly though significantly linked to the local climate. Intraspecific diversity, associated with adaptation to local conditions, can be exploited in breeding for climate‐resilient cultivars.
