The structures were further supported by co-TLC with authentic compound samples or hydrolysis followed by co-TLC with authentic compound samples (see supplementary data).…”

Antioxidant and Hepatoprotective Activities of Thai Mango Seed Kernel Extract

“…The isolated compounds (1-3)(l " Fig. 2) were characterized by spectroscopic analysis, including UV, MS, IR, 1 H-NMR, and 13 C-NMR techniques, and comparison of these data with those in the literature [10][11][12][13][14]. The purities of these isolated MG, GA, and PGG (101.1, 95.9 and 86.1 %, respectively) were analyzed by high performance liquid chromatography (HPLC).…”
