[Pharmacology and toxicology of Guatteria gaumeri and alpha-asarone].

Guatteria gaumeri Greenman (Annonacease) has been used as bark infusion in the traditional mexican medicine for the treatment of hypercholesterolemia and cholelithiasis. The main component is alpha-asarone which has been isolated by different extraction procedures and subsequently synthetized, as well as 16 analogs, derivatives of 4-propenyl-1,2-dimethoxybenzenes 5-substituted. After daily dosing per os of 80 mg/kg of alpha-asarone and the amino and metoxi analogs for seven days to hypercholesterolemic male rats, cholesterol decreased 57.3, 37.5 and 46.9% and triglycerides diminished 42.5, 67.…

Bioactivity and chemical composition of the essential oil from the leaves of Guatteria australis A.St.-Hil.

Essential oil from the leaves of Guatteria australis was obtained by hydrodistillation, analyzed by Gas Chromatography coupled to Mass Spectromery (GC-MS) and their antiproliferative, antileishmanial, antibacterial, antifungal and antioxidant activities were also evaluated. Twenty-three compounds were identified among which germacrene B (50.66%), germacrene D (22.22%) and (E)-caryophyllene (8.99%) were the main compounds. The highest antiproliferative activity was observed against NCI-ADR/RES (TGI = 31.08 μg/ml) and HT-29 (TGI = 32.81 μg/ml) cell lines. It also showed good antileishmanial acti…

A search for natural bioactive compounds in Bolivia through a multidisciplinary approach. Part I. Evaluation of the antimalarial activity of plants used by the Chacobo Indians.

Thirty extracts of plants traditionally used by the Chacobos, a native community living in the Amazonian part of Bolivia, were screened in v … amazonica) used as a piscicide displayed good in vitro activity, in the same way as one Annonaceae, Guatteria aff. schomburgkiana, used for construction purposes.

In Vitro Trypanocidal and Antibacterial Activities of Essential Oils from Four Species of the Family Annonaceae.

The objective of this study was to evaluate the chemical composition, and the trypanocidal and antibacterial activities of the essential oils from four species of Annonaceae: Bocageopsis multiflora (Mart.) R.E.Fr., Duguetia quitarensis Benth., Fusaea longifolia (Aubl.) Saff., and Guatteria punctata (Aubl.) R.A.Howard. The chemical composition of the essential oils from the aerial parts yielded 23, 20, 21 and 23 constituents, respectively, which were identified by GC/MS. The trypanocidal activity was evaluated against the amastigote and trypomastigote forms of T. cruzi. The antibacterial activi…

Essential oils and their constituents as anticancer agents: a mechanistic view.

Exploring natural plant products as an option to find new chemical entities as anticancer agents is one of the fastest growing areas of research. Recently, in the last decade, essential oils (EOs) have been under study for their use in cancer therapy and the present review is an attempt to collect and document the available studies indicating EOs and their constituents as anticancer agents. This review enlists nearly 130 studies of EOs from various plant species and their constituents that have been studied so far for their anticancer potential and these studies have been classified as in vitr

Кровавая добавка и болезни человека: обзор клинических испытаний.

Медицинальные свойства турмеров (Curcuma longa L.) — растения, использовавшегося на протяжении веков в качестве противовоспалительного средства, объясняются его полифеноловыми каркуминоидами, где преобладает кёркумин. Хотя «куркуминовые» добавки являются топ-продаваемыми ботаническими с перспективными доклиническими эффектами, остаются вопросы о биологической активности у человека. Для решения этой проблемы был проведен обзор аналитического исследования с целью оценки клинических испытаний человека, в ходе которых сообщалось о пероральном воздействии каркумина на результаты лечения.
