Examination of nasal and vaginal swabs collected from 12 diseased buffaloes led to the isolation of three paramyxovirus isolates from two animals.
Substantial efforts over the last years led to the isolation of cell sublines with increased susceptibility24, 35,36,37.
Bioassay-driven purification of B. fragilis supernatant led to the isolation of the growth factor, which, surprisingly, is the major inhibitory neurotransmitter GABA (γ-aminobutyric acid).
& Zucc (Aristolochiaceae) led to the isolation of major compound (1) as light brown grainy crystals.
Therefore further chemical investigation was focused on this fraction, which led to the isolation of compounds 1 3.
Chemical studies using mangrove plants have led to the isolation of over 200 bioactive compounds [8, 9].
Previous investigation on the fruiting bodies of E. goetzii has led to the isolation of neoengleromycin, cytochalasin D and 19,20-epoxycytochalasin 19,20-epoxycytochalasin
Further separation and purification of this fraction led to the isolation of two new steroids, mekongsterols A (1) and B (2), together with seven known compounds (3 9).
Then, bioassay-guided chemical investigation of the crude extract led to the isolation of 22 phenolic compounds, and they showed striking radical-scavenging activities.
The present phytochemical investigation of the wood of AH led to the isolation of two new flavonoids (1, 2) and five known compounds (3−7).
T. conoides is rich in polyphenolic substances [36, 37] and phytochemical investigation led to the isolation of sulfated polysaccharides [30, 38].
