Phytochemical investigation of the bark of Guatteria hispida afforded three new alkaloids, 9-methoxy-O-methylmoschatoline (1), 9-methoxyisomoschatoline (2), and isocerasonine (3), along with 10 known alkaloids, 8-oxopseudopalmatine (4), O-methylmoschatoline (5), lysicamine (6), liriodenine (7), 10-methoxyliriodenine (8), nornuciferine (9), anonaine (10), xylopine (11), coreximine (12), and isocoreximine (13). The major compounds, 2, 6, 12, and 13, showed significant antioxidant capacity in the… 

In vitro Antiproliferative and Antibacterial Activities of Essential Oils from Four Species of Guatteria

E evaluation of antiproliferative activity of the EOs showed strong selectivity against the tumor cell line OVCAR‐03 (ovarian cancer), i.e., more active than the positive control doxorubicin (11.7 μg/ml).

Antioxidant and antimicrobial activities of aporphinoids and other alkaloids from the bark of Annona salzmannii A. DC. (Annonaceae)

The antioxidant capacity by oxygen radical absorbance capacity (ORAC)-FL method and antimicrobial activity using the broth microdilution method of aporphinoids and other alkaloids isolated from the bark of Annona salzmannii A. DC were evaluated.

Chemical Composition and Antioxidant, Antimicrobial, and Larvicidal Activities of the Essential Oils of Annona Salzmannii and A. pickelii (Annonaceae)

The essential oils from the leaves of Annona salzmannii and A. pickelii showed significant antioxidant capacity in the ORACFL and DPPH assays and the antimicrobial activity of these essential oils was also evaluated against bacteria and fungi, as well as the larvicidal activity against Aedes aegypti larvae.

Chemical Composition and Antimicrobial Activity of Essential Oil from the Leaves of Cyrtocymura scorpioides

The genus Cyrtocymura (Asteraceae) comprises six species distributed in South and Central America, mainly in Brazil [1]. Chemically the genus contains sesquiterpene lactones [2, 3] and eudesmane

Anti-inflammatory, antinociceptive and antioxidant activities of the hydromethanolic fraction from Annona nutans leaves

It is indicated, for the first time, that FHMeOH has anti-inflammatory, antinociceptive and antioxidant potential, and it is a promising source of studies for new herbal medicines.

Chemical composition and antiparasitic activity of essential oils from leaves of Guatteria friesiana and Guatteria pogonopus (Annonaceae)

The results presented herein reinforce the potential of other members of this family for search of antiparasitic compounds, especially in the cell membrane, Golgi complex, endoplasmatic reticulum and mitochondria.


Flowering plants in West Africa: Annonaceae – soursop family

A pantropical but especially Old World family of woody plants, found in West Africa mainly as shrubs, lower-storey trees and lianes in forest, members of the family may be recognised by their two-ranked, conduplicate, simple, existipulate, entire leaves, aromatic wood and fragrant three-part, often downward-facing flowers.
