In soybean, triterpenoid saponin is one of the major secondary metabolites and is further classified into group A and DDMP saponins. Although they have known health benefits for humans and animals, acetylation of group A saponins causes bitterness and gives an astringent taste to soy products. Therefore, several studies are being conducted to eliminate acetylated group A saponins. Previous stud...

Centella asiatica (L.) Urb. is one of the important medicinal and nutraceutical herbs being used by ethnic people since prehistoric times. It accumulates large amount of pentacyclic triterpenoid saponins which forms the major store house of secondary metabolites providing active compounds stimulating cell rejuvenation, improving physical and mental health. C. asiatica also serves dietetic purpo...

Duas novas e duas conhecidas saponinas triterpênicas foram isoladas da casca do caule de Pentaclethra macroloba. As estruturas foram determinadas usando uma combinação de técnicas de RMN homo(1D: RMNH, RMNC-{H}, RMNC-DEPT135; 2D: H-H-COSY, H-HTOCSY, H-H-NOESY) and heteronuclear 2D (HMQC and HMBC), espectros de massas obtidos com ionização por pulverização eletrônica (ESIMS) e métodos químicos. ...

There is growing interest in development of natural products as anti-cancer and chemopreventive agents. Many triterpenoids have been proved as potential agents for chemoprevention and therapy of breast cancer. Ginsenosides from ginseng, which mostly belong to dammarane-type triterpenoids, have gained great attention for their anti-breast cancer activity with diverse mechanisms. However, studies...

Endophytes of medicinal plants have the capacity to synthesis same or similar active substances with their hosts. To investigate the diversity and capacity to produce saponins of endophytic fungi of Panax ginseng, thirty-eight strains of were isolated. Polymerase chain reaction (PCR) and sequencing were used to identify the isolates, and saponins concentrations in the cultures were measured. Ag...
