Growth curve, biochemical profile and phytochemical analyses in calli obtained from the procambium segments of Bacupari

ABSTRACT

Garcinia brasiliensis, popularly known as Bacupari, is native to the Amazon and commonly used in folk medicine for its therapeutic properties. This plant is rich in bioactive compounds like benzophenones. However, there are no works about the in vitro establishment and achievement of secondary metabolites in this plant. Thus, the aim of this work was to determine the growth curve and to perform the biochemical and phytochemical analyses in calli obtained from the procambium segments of Bacupari. The growth curve of calli followed a sigmoidal pattern, with four distinct phases (lag, exponential, linear, deceleration). Total soluble sugars were higher on the inoculation day and the reducing sugars on the 20 th day. Amino acids increased from the 60 th day up to the stabilization on the 120 th day. The protein content varied, but it seemed to be related to the amino acids metabolism. The phytochemical screening showed the presence of phenolic and flavonoid compounds in the calli and the HPLC analysis allowed the identification of Fukugetin, Guttiferone A and 7-epiclusianone.
