In the original version of this article published on 12 July 2023, Fig. 4 contained an error due to a mistake while typesetting. The number labels in Fig. 4 1), which shows the chemical structure of olean-12-en-28-oic acid 3-O-monodesmoside, are incorrect. The incorrect “oleanolic acid 3-O-glucuronide (18)” has now been replaced with the correct “oleanolic acid 3-O-glucuronide (16)”, and the incorrect “momordin lc (16)” has now been replaced with the correct “momordin lc (14)”.
