Plants have been an important source of medicine for thousands of
years. Plants are rich source of natural antioxidant i.e.
tocopherols, vitamin C, flavonoids and phenolic compounds. Whole
plant samples of Swertia chirata were purchased from the local
market of Faisalabad, Pakistan. The dried and ground sample
subjected for extraction by shaking method with different solvents
i.e. 75% methanol and ethanol. In the present study antioxidant
activity of plant Swertia chirata was investigated by measuring
total phenolics (TPC), total flavonoids (TFC), DPPH (2,
2-Diphenyl-1-picrylhydrazyl) and Percent inhibition of linoleic
acid peroxidation. The total phenolics (TPC) obtained from methanol
2.565g / 100g from ethanol 1.612g / 100g gallic acid equivalents.
TFC obtained from methanol 13.247g / 100g from ethanol 10.948g /
100g catechin equivalents, inhibition of linoleic acid peroxidation
obtained from methanol 94.04% from ethanol 93.05% and Percentages
scavenging of plant Swertia chirata obtained from methanol extract
84.32% from ethanol extract 82.54%.
Until now more than one hundred forms of cancer and variety of
infection have been recognised and almost every second tissue in
the body can become a source of one type of malignancies or even of
several types. The chance of recovery of tumour depends upon the
stage and the type of the tumour that is primary or secondary
(metastatic). The selection of treatment technique in tumour
therapy is critical in giving the patient the best possible
prognosis. Today commonly known strategies to treat cancer patients
are surgery, external radiation therapy and chemotherapy,
regardless of its limited effectiveness in metastasis stage of
cancer. Surgery can often prove very effective in removing primary
tumours but can do little in terms of micro-metastasis and
discovering small or inconspicuous neoplasms. This is being the
primary focus of target specific radionuclide therapy. Selective
delivery of the radionuclide at the site of malignancies would make
therapeutic radiopharmaceuticals a suitable addition to other
existing strategies. The study should help nuclear medicine
students/researchers in accessing the newly developed
radiopharmaceuticals for diagnosis.
