4. Why Xlaria spp.?
Xylaria is a large and the first described genus of the family Xylariaceae
They may be Lived as a Saprophytes or sometimes Parasitic or
Endophytes.
They may be found mostly on wood, sawdust, leaf, dung or soil.
It is a natural source of bioactive secondary metabolites like
Cytochalsins (Dagne et al., 1994), Xylaramides (Schneider et al., 1996),
Xanthones (Healy et al., 2004) and Griesofulvins (Park et al., 2005). etc.

ethers.
Absorption peak at 396 nm

Abs
The tentatively assigned peak at 3438 cm-1
indicates the presence of hydrogen bonding (OH
or NH).
The band around 2935 cm-1 is due to H-C-H
symmetric stretching.
The broad peak at 1699 cm-1 is due to C=O
stretching and the peaks at 1454, 1390-1228 &
1053 indicate C-C=C asymmetric, N-
H and C-O stretches.

13. CONCLUSION
Present study revealed that the fruiting body extract of Xylaria sp.
(KC405623) had an effective broad spectrum antibacterial and cytotoxic
activity against drug resistant bacterial pathogens and human cancer
cell lines.
Xylaria sp. (KC405623) could be used as pharmaceutical substances
having diverse therapeutic applications once the nature of active
components will be elucidated.
