Abstract/OtherAbstract:
Thirty secondary plant substances were detected in various extracts of the leaves, fruits, stem and bark of Caraipadensifolia Mart. Phenolic compounds were preliminarily identified and quantitated by HPLC-ESI-MS and the structures of the compounds, purified by semi-preparative HPLC, were further characterized by nano-ESI-MS-MS. The presence of gallic acid, 3,4-dihydroxybenzoic acid, neochlorogenic acid, chlorogenic acid, methyl gallate, p-coumaric acid quinate, epicatechin, procaynidin dimer B(2), procyanidin trimer C(1), syringic acid, 1,2,3,6-tetragallate glucoside, 1,3,4,6-tetragallate glucoside, corilagin, ellagic acid, methyl ellagic acid rhamnoside, quercetin-3-O-rhamnoside, two apigenin-C-glycosides (vitexin and isovitexin) and two luteolin-C-glycosides (orientin and isoorientin) are reported in this species for the first time. In addition, the previously reported following terpenoids, lupeol, lupenone, betulinic acid, betulin, friedelin and a previously non-characterized terpenoid in this species, friedelinol were identified and quantitated by GC-MS. A previously identified sterol was beta-sitosterol along with stigmasterol in this species for the first time. The vitamins alpha-tocopherol and gamma-tocopherol were also identified in extracts of the leaves of Caraipa species for the first time. The data shows that the botanical parts of C. densifolia Mart. has a much richer spectrum of secondary plant substances than previously reported.
