Chemical Constituents of Muehlenbeckia tamnifolia (Kunth) Meisn (Polygonaceae) and Its In Vitro α-Amilase and α-Glucosidase Inhibitory Activities
Four of the nine isolated compounds exhibited strong inhibitory activity with IC50 values below 8 µM, much higher than acarbose (377 uM).
Antifungal acylcyclopentenediones from fruiting bodies of Hygrophorus chrysodon.
Initial tests indicated interesting antifungal activity of chrysotriones against Fusarium verticillioides, one of the common worldwide pathogens of cultivated plants, and suggest an unprecedented biosynthetic pathway, starting from fatty acid derivatives.
Phytochemical Study of the Ecuadorian Species Lepechinia mutica (Benth.) Epling and High Antifungal Activity of Carnosol against Pyricularia oryzae
The anti-fungal activity of non-volatile secondary metabolites from the leaves and the chemistry of the essential oil distilled from the flowers were tested in vitro, with carnosol resulting in being very active against the “blast disease” caused by the fungus Pyricularia oryzae.
Phytochemical researches and antimicrobial activity of Clinopodium nubigenum Kunth (Kuntze) raw extracts
The essential oil of the species Clinopodium nubigenum (Kunth) Kuntze, Lamiaceae, was analyzed and two nonvolatile compounds, named schizonepetoside A and schiz onepedoside C, have been isolated, which are rare glycosyl terpenoids, which were previously isolated from only one plant, but never found before in the genus Clinicopodium.
Sesquiterpenes of Lactarius and Russula (Mushrooms): An Update[1]
In this review the biogenesis, structures, and bioactivities of all sesquiterpenoids isolated from Russula and Lactarius species in the last decade are critically discussed, and divided into sections
New anthracene derivatives from Coussarea macrophylla.
Five new naturally occurring anthracene derivatives were isolated from Coussarea macrophylla along with three known compounds, 3-hydroxy-1-methoxy-2- methoxymethylanthraquinone, scopoletin, and 3-epi-pomolic acid.
