Phytomedicine refers to the use of any plant part for
medicinal purposes. Estimates of 25% of currently used prescribed drugs are
chemically altered natural products and another 25% comes directly from the
arena of herbal medicine. In addition, evidences drawn from the studies of
Arvigo et al (1993) showed an estimate of 119 chemical substances were obtained
from 90 different plant species. In 74% cases, an active substance was isolated
from a plant which had been used in the traditional system of medicine,
revealing the primary importance medicinal plants in the healthcare system.
This is due to the fact that, plants contain various secondary metabolites
serving as the source of novel therapeutic compound conferring improvement of
human health with controlled adverse effects. Various medicinal products likeanti-microbial agents, cardiotonic agents, Central nervous system (CNS)stimulants, nutraceuticals, sweeteners, animal feed, etc, are derived from the
natural source, natural product can also have the potentiality of anticancer
agent.Thus the present study aims at the preliminary phytochemical screening
and the evaluation of diverse pharmacological activities of the methanol
extract of Murdannianudiflora, Tradescantiapallida and Piper nigrum as well as
their organic soluble partitionates.
The plants employed for the study had some notable
compound that have elucidated significant therapeutic activity such asanthrocyanidins isolated from Tradescantia pallid was investigated as potential
food pigment as well as various flavonoid compound isolated from the seeds of
Piper nigrum such as piperine, Limonen, Sabinene in abundance as well as
b-cryophyllene, Piperolein B, Dehydropipernonaline, Piperlongumininehas been
investigated for its therapeutic role as major antioxidant compounds.
