| dc.description.abstract | Eleven species of the genus polygonum
(family: Polygonaceae) are found in Kenya. They
appear in the "key to species" in,the following
order: P.baldschuriacum Regel, P.convolvulus L,
P.nepalense Meisn, P.capitatum Han, P.afromantanum
Greenway, P.aviculare L, P.strigosum R.Br.,
P.salicifolium wild, P.senegalense Meisn,
P,pulchrum Blume and P.setosulum A. Rich.
Chemical screening by a process of sequential
non-polar and polar solvent extraction (petroleum
ether, chloroform and methanol along with acid
hydrolysis), chromatographic separation followed
by spectroscopic (lH and l3C NMR, UV,. IR and MS)
analysis was performed on the latter four species..... | |
