Macrocarpane, a New Sesquiterpene Skeleton from the Leaves of Porcelia macrocarpa
O óleo volátil e o extrato hexânico das folhas de Porcelia macrocarpa (Warm.) R.E. Fries, Annonaceae, foram submetidos a fracionamentos cromatográficos. Nove sesquiterpenos (α-cubebeno, α-copaeno, germacreno-D, biciclogermacreno, γ-cadineno, δ-cadineno, espatulenol, globulol e cis-cubenol) além de um diterpeno (fitol) foram identificados no óleo volátil, correspondendo a 83.1% (em massa) do tot...
متن کاملAntitrypanosomal Acetylene Fatty Acid Derivatives from the Seeds of Porcelia macrocarpa (Annonaceae).
Chagas' disease is caused by a parasitic protozoan and affects the poorest population in the world, causing high mortality and morbidity. As a result of the toxicity and long duration of current treatments, the discovery of novel and more efficacious drugs is crucial. In this work, the hexane extract from seeds of Porcelia macrocarpa R.E. Fries (Annonaceae) displayed in vitro antitrypanosomal a...
متن کاملThe seasonal variation of the chemical composition of essential oils from Porcelia macrocarpa R.E. Fries (Annonaceae) and their antimicrobial activity.
This study investigates the impact of seasonal variation on the chemical composition of essential oils from the leaves of Porcelia macrocarpa (Annonaceae) obtained over the course of one year (January-December 2011) and the chemical composition of the essential oils obtained from the ripe fruits of the same plant. Furthermore, the essential oils of the leaves were investigated with respect to t...
متن کاملDevelopment of Phaleria macrocarpa (Scheff.) Boerl Fruits Using Response Surface Methodology Focused on Phenolics, Flavonoids and Antioxidant Properties.
In this study, the optimal conditions for the extraction of antioxidants from the Buah Mahkota Dewa fruit (Phaleria macrocarpa) was determined by using Response Surface Methodology (RSM). The optimisation was applied using a Central Composite Design (CCD) to investigate the effect of three independent variables, namely extraction temperature (°C), extraction time (minutes) and extraction solven...
متن کاملIn vitro study of flavonoids, fatty acids, and steroids on proliferation of rat hepatic stellate cells.
There is a wealth of evidence that hepatic stellate cells (HSCs) orchestrate most of the important events in liver fibrogenesis. After liver injury, HSCs become activated to a profibrogenic myofibroblastic phenotype and can regulate net deposition of collagens and other matrix proteins in the liver. The proliferation of HSCs is mainly stimulated by the platelet-derived growth factor (PDGF). In ...
