Folate metabolism is important for the transfer of a methyl methylene or formyl group and in the transformation of certain amino acids as well as in the synthesis of purines and pyrimidine needed for the synthesis of dioxyribonucleic acid (DNA).
The aglycone of saponin 13 is a triterpenic acid with MM 472 u known as hederagenin, while for saponin 12, the aglycone is a triterpenoid known as aglycone B (3-hydroxy-23-oxoolean-12-en-28-oic acid) with MM 470 u, which contains a C-23 formyl group in the aglycone core.
The quaternary salts on acidic hydrolysis removed the formyl group and led to the formation of diammonium HCl salts 7a and 7b.
