There is a book about that, so here is the abstract:
The manner in which fungal endophytes activate host stress response systems is unknown; the occurrence of additional mechanisms involved in symbiotically-conferred stress tolerance in mangrove plants (the primary producers of estuarine food chain) is also an unresolved issue. Here, we report antioxidant potentials of four different mangroves and their endophytic fungi. We elucidated the possible roles of antioxidants in symbiotic association between mangroves and their endophytic fungi. Four different mangrove species and the predominant endophytic fungus Aspergillus flavus were analyzed using various in vitro assay systems (such as iron chelating capacity, reducing power, and hydroxyl radicals/hydrogen peroxide/l-diphenyl-2-picrylhydrazyl radical scavenging and inhibition of lipid peroxidation using the β-carotene–linoleate model system). In vitro models clearly established the antioxidant potency of extracts of mangrove plants and their respective endophytic fungi, which aids in understanding the mutualistic associations of plant and endophyte against various biotic and abiotic stresses. Re-infection analysis of endophytic A. flavus in tobacco plants confirmed the endophytic status of the fungus and its enhancement effect on plant growth.

I wouldn't know the answer to your question, but I 'm interested in reading more.
I wouldn't know the mechanisms of action of ingested tropical plants and fruits. But I have a personal healthy rule, that I follow with success:
When I travel abroad, I always eat local food, because it is better adapted to the geographic regions I visit. And at home, I tend to eat seasonal fruit, because local fruits are best edible and better for health, in the right season.
This evening, there were strawberies at the supermarket. I didn't bring any, because this is not the right season. (they must have been frozen and defrost, and lost quality. Strawberies are the richest fruits in Vitamin C, and the best antri-oxidants in Europe, and I will need them next Spring, in April, which is their right season.
Many mangrove systems have become degraded and destroyed. As a result of conversion to development, aquaculture or agriculture, over-harvesting for timber, unsustainable fishing and other extractive uses, the worldwide mangrove area fell.
Not only mangroves and mangrove associates but also many other species of plants have been reported to be a good source of anti-oxidants. I would just say here that the antioxidant activity is related to the chemicals (may be present in any source) which show diverse mechanisms to conquer the free radicals of our body (by the proton transfer to free radical, or donate electrons to some ions like ferric).
