Underutilized Annona Species from the Brazilian Cerrado and Amazon Rainforest: A Study on Fatty Acids Profile and Yield of Seed Oils

Annona (Annonaceae) is an important source of fruits in the Brazilian Cerrado and the Amazon Rainforest. Some Annona species are widely commercialized as fresh fruit or as frozen pulp. Seeds are accustomedly discarded. Our main goal was to analyze fatty acids profile from seeds of A. crassiflora and A. coriacea from Cerrado, A. montana from Amazon Forest, and three cultivars (A. cherimola cv. Madeira, A. cherimola x A. squamosa cv. Pink`s Mammonth and A. cherimola x A. squamosa cv. Gefner). The total oil yield ranged between 20 and 42% by weight of dry mass. The A cherimola x A. squamosa cv. Gefner has significantly higher total lipid yield than all other samples. 100 g of fruit of this species present 6-8 g of seeds. Considering the fruit production of Chile (over 221 ton of fruits/year), more than 1300 ton of seed/year could be obtained, which could provide at least 200 ton of seed oil. Oleic acid was predominant for most samples, but for A. montana linoleic acid was the most abundant FA. Phenotypic variation on FAME profile was observed. These new data are an urgent requirement for supporting conservation programs, mainly for Cerrado areas in Brazil.
