In-Depth Information
Compounds and activities: The bioactive compound, muscoride A, isolated
from this species has antibacterial properties (Rao, 2004), and nostopeptin
A and B (cyclic depsipeptides) of this species are elastase and chymotrypin
inhibitors. Other compounds present in this species are microviridins B and
H (cyclic peptides). The extract of this species has also shown antibacterial
and antifungal activities, and the values of inhibition zone diameter (mm)
recorded for the bacterial species,
S. epidermidis
,
S. aureus
,
S. haemo-
lyticus
,
P. vulgaris
,
and
S. sonnei
, were found to be 22, 24, 16, 18, and
15, respectively. Similarly, the values for the antifungal species,
C. krusei
,
C. albicans
,
A. niger
,
A. fumigatus
,
and
C. neoformans
, were 9, 8, 9, 7, and
10 mm, respectively (Ramamurthy et al.,
2012).
