Urban Farm DB summary
Dried leaf bark and freeze-dried gel from Aloe vera grown in community gardens in Palmas, Tocantins, Brazil were analyzed for chemical composition, phytochemistry, and heavy metals. Moisture content ranged from 7.06 to 10.62%, ash from 13.62 to 32.63%, crude protein from 5.58 to 7.47%, lipids from 0.58 to 2.04%, and crude fiber from 16.22 to 16.49%. Phytochemical analysis identified gallic acid, catechin, gallocatechin, ellagic acid, naringin, myricetin, quercetin, and kaempferol. No heavy metals were detected in the samples analyzed. The authors note further research is needed on how seasonality affects these compounds.
