文摘

Computer program for proanthocyanidins (PAs) data processing was developed. Isotope patterns of A-, B-type, and multi-charged PAs ions by ESI HRMS are deconvoluted. The program can provide identification and quantitation results for PAs from UHPLC-HRAM-MS data. The entire execution time is about 1 min for data processing after data format conversion.
