Triterpenes from the resin of Protium heptaphyllum

Fitoterapia, 2001
From the neutral fraction of the resin of Protium heptaphyllum, a mixture of alpha- and beta-amyrin, a mixture of maniladiol and brein have been isolated as main components, and the novel 3 beta,24-dihydroxy-urs-12-ene (1), 3-oxo-20S-hydroxytaraxastane (2) and 3 beta,20S-dihydroxytaraxastane (3) as minor components. NMR data of the last three compounds

Oxidation of monoterpenes in Protium heptaphyllum oleoresins

Phytochemistry, 2017
Protium heptaphyllum (Burseraceae) oleoresins are rich in volatile monoterpenes, exhibiting a chemical composition that can be strongly altered with time. The present work aimed to discuss the temporal change of the volatile composition of these oleoresins, and search for related supporting evidence. Samples of P.

Evaluation of supercritical fluid extraction of tacamahaco (Protium heptaphyllum) resin

Journal of Essential Oil Research, 2017
AbstractAn experimental design 23 was developed to investigate the effect of operating pressure (80–100 bar), operating temperature (40–60 °C) and static extraction time (30–35 min) on extraction yield and on its quality during supercritical carbon dioxide extraction from the resin of Protium heptaphyllum (Aubl.) March.

Volatile Constituents from Oleoresin ofProtium heptaphyllum(Aubl.) March

Journal of Essential Oil Research, 1999
Abstract The composition of essential oils from two sources of oleoresins of Protium heptaphyllum were analyzed by GC/MS and Retention Index. The composition of the oils varied according to fresh or aged resin. The oil of fresh resin was rich in α-terpinene (18.0%), p-cymene (36.0%) and γ-terpinene (12.0%), whereas the aged resin oil contained p-cymene

Volatile Constituents from Leaves and Stems ofProtium heptaphyllum(Aubl.) March.

Journal of Essential Oil Research, 1995
ABSTRACT The essential oils from the leaves and stems of Protium heptaphyllum were analyzed by GC/MS. The major volatile constituents obtained from the leaves were terpinolene (15.45%), β-elemene (22.09%) and β-caryophyllene (11.11%), while the main component of the stem oil was terpinolene (40.28%).

A possible mechanism for anxiolytic and antidepressant effects of alpha- and beta-amyrin from Protium heptaphyllum (Aubl.) March

Pharmacology Biochemistry and Behavior, 2006
In the present study, we examined the anxiolytic and antidepressant effects of the mixture of alpha- and beta-amyrin (AMY), pentacyclic triterpenes isolated from the stem bark resin of Protium heptaphyllum. These effects of AMY were demonstrated by the open-field, elevated-plus-maze, rota rod, forced swimming, and pentobarbital-induced sleeping time ...
