Research conducted by Kasetsart University, Thailand, and Massey University, New Zealand, examines the anthocyanin levels present in mangosteen (Garcinia mangostana L.), a widely favored tropical fruit in Southeast Asia. The research highlights the high anthocyanin content in the pericarp, which contrasts with the white edible aril that lacks these compounds. Anthocyanins are the major pigments responsible for the red-to-purple coloration of the pericarp, serving as an indicator of fruit maturity.
The primary anthocyanins identified are cyanidin-sophoroside and cyanidin-glucoside. The synthesis of these pigments involves the coordinated expression of multiple genes, including at least eight encoding enzymes and three transcription factors. The study found that ripening-induced anthocyanin accumulation is regulated by endogenous ethylene, which controls the expression of key genes.
The research also compares anthocyanin synthesis in mangosteen with other fruit species under various conditions such as light, temperature, and the influence of plant growth regulators. This comprehensive examination provides valuable insights into the genetic and biochemical pathways of anthocyanin synthesis in mangosteen, contributing to a better understanding of its medicinal and pharmaceutical properties.
