Fungicidal and molluscicidal saponins from Dolichos kilimandscharicus

  title={Fungicidal and molluscicidal saponins from Dolichos kilimandscharicus},
  author={A. Marston and F. Gafner and S. F. Dossaji and K. Hostettmann},
Abstract Three saponins with molluseicidal and fungicidal activities have been isolated from the roots of Dolichos kilimandscharicus . They were shown to be the 3- O -β- d -glucopyranosides of hederagenin, bayogenin and medicagenic acid. 
Search for molluscicidal and antifungal saponins from tropical plants.
Tropical plants are useful sources of saponins and these are being intensively investigated in order to find new triterpene glycosides which might find application in the management of schistosomiasis and fungal infections. Expand
Growth inhibitory activities of kalopanaxsaponins A and I against human pathogenic fungi
It was found that kalopanaxsaponins A and I were effective in inhibiting the growth of Candida albicans and Cryptococcus neoformans with minimum inhibitory concentration (MIC) of 25 μg/ml. Expand

Oleanane saponins from Bellis sylvestris Cyr. and evaluation of their phytotoxicity on Aegilops geniculata Roth.
Six oleanane saponins were isolated for the first time from leaves of Bellis sylvestris Cyr., the southern daisy. Their structures were established by the extensive use of 2D-NMR experiments,Expand
In vitro anti‐Malassezia activity and potential use in anti‐dandruff formulation of Asparagus racemosus
The study was conducted to evaluate anti‐fungal activities of the extracts obtained from the roots of Asparagus racemosus Willd against Malassezia furfur and M. globosa. Expand
Results to date support the hypothesis that ginsenosides are phytoanticipins and serve as host resistance factors, although different fungi and oomycotan organisms appear to be differentially affected by them in vitro. Expand
Cytotoxic 16-beta-[(D-xylopyranosyl)oxy]oxohexadecanyl triterpene glycosides from a Malagasy plant, Physena sessiliflora.
Brine shrimp lethality assay-guided separation of the MeOH extract of leaves of Physena sessiliflora, which is endemic to Madagascar, afforded eight triterpene glycosides, Physenoside S1-4 andExpand
A saponin isolated from Agapanthus africanus differentially induces apoplastic peroxidase activity in wheat and displays fungicidal properties
In vitro peroxidase enzyme activity increased significantly in wheat seedlings 48 h after treatment with the purified saponin, demonstrating its role as an elicitor to activate a defence reaction in wheat. Expand

Alfalfa (Medicago sativa L) is a valuable source of good quality protein in temperate climates and there has been increasing interest in using lucerne as sprouts for green salad, or in the form of tablets or juice, for its effect on serum cholesterol. Expand
Structure-activity relationships of the saponin α-hederin
The terminal rhamnose is more important for antifungal activity than for hemolytic activity, whereas the free carboxylic acid is moreImportant for the latter than for the former. Expand
