| synergistic antihyperglycemic effects between plant-derived oleanolic acid and insulin in streptozotocin-induced diabetic rats. | studies from our laboratories indicate that syzygium cordatum leaf extract contains triterpene mixtures [oleanolic acid (oa) and ursolic acid (ua)] with hypoglycemic properties. the aims of this study were to investigate the hypoglycemic effects of syzygium aromaticum-derived oa and whether oa influenced the blood glucose lowering effects of insulin in streptozotocin (stz)-induced diabetic rats. we envisaged that oa may provide a strategy with different mechanism of action for effective diabetic ... | 2010 | 20662697 |
| an antimicrobial investigation of plants used traditionally in southern africa to treat sexually transmitted infections. | eighteen plants were assessed for antimicrobial activity against pathogens associated with prevalent urogenital/sexually transmitted infections. plant selection was based on information obtained from the ethnobotanical literature. | 2010 | 20561928 |
| renal effects of plant-derived oleanolic acid in streptozotocin-induced diabetic rats. | previous studies from our laboratories indicate that the anti-diabetic effects of syzygium cordatum (hochst.) [myrtaceae] leaf extract in streptozotocin-induced diabetic rats may be attributed in part to mixtures of triterpenes, oleanolic acid (3ss-hydroxy-olea-12-en-28-oic acid, oa) and ursolic acid (3ss -hydroxyl-urs-12-en-28-oic acid, ua). for the bioactive compounds to have potential in diabetes management, they should alleviate or prevent complications of diabetes mellitus, kidney function, ... | 2009 | 19839826 |
| molecular and phenotypic characterization of three phylogenetic species discovered within the neofisicoccum parvum/n. ribis complex. | neofusicoccum parvum and n. ribis are closely related species whose identities often have been confused. these fungal plant pathogens were identified recently as the most abundant species of botryosphaeriaceae (ascomycetes) isolated from native syzygium cordatum trees in south africa. in another study using multiple gene genealogies from five nuclear loci three undescribed cryptic phylogenetic species as well as n. parvum were identified among 30 of these isolates. the aim of this study was to c ... | 2009 | 19750943 |
