From these results, the diterpenoids
from GF were confirmed to be the toxic components after oral administration at four dosages.
Antifungal activity of neo-clerodane diterpenoids
the most active principle among three major diterpenoids
(borapetosides A, B, and C) isolated from ethanol extract of Tinospora crispa vines.
Vitex rotundifolia), a member of the family Verbenaceae, is known to produce a variety of diterpenoids
(Alam et al.
From fractions 1-3 three known abietane-type diterpenoids
, namely royleanone, 15-deoxyfuerstione and taxodione, were isolated and from fraction 5-a new taxodione derivative was obtained.
are excreted into the growth medium offering easy isolation.
These compounds are the most diverse of the diterpenoids
isolated from species of Plectranthus.
Another plant chemical, called diterpenoids
occurring in Rhododendrons, were found to be poisonous to honeybees and a wild mining bee species.
Inhibition of lipid peroxidation and superoxide generation by diterpenoids
from Rosmarinus officinalis.
from Azorella compacta (Umbelliferae) active on Trypanosoma cruzi.
The pitch contains several other diterpenoids
with very similar properties, so it is not easy to separate and purify.
Through this collaboration, the team successfully identified the large number of novel mystery compounds as ent-kaurane-related diterpenoids
, termed "kauralexins," and modified C15 carboxylic acids of b-macrocarpene, termed "zealexins.
