ABSTRACT
Background: The current research was undertaken on dried fruits of Capparis moonii to screen its potential for immunomodulatory and cancer indications with identification of phytoconstituents by chromatographic techniques.Methods: Methanolic (MECN), hydro-methanolic (HMECN) and aqueous extracts (AQCN) of Capparis moonii were subjected to high performance thin layer chromatography (HPTLC) and high-performance liquid chromatography (HPLC) after studying the total phenolic and flavonoid content by using rutin and gallic acid as standards respectively as well as undertaking powder characteristics and preliminary phytochemical screening. Immunomodulatory activities covered were hemagglutination antibody titre and delayed-type hypersensitivity reaction with the aid of sheep red blood cells (0.5×109) as antigens. The extracts were studied for antioxidant potential. Anticancer prospects were focusing on in vitro cell lines screening (MCF 7 and HCT 15) by Sulforhodamine B assay method and potato disc assay.Results: The total phenolic and flavonoid content of MECM, HMECM and AQCM fruits extracts were found to be 0.20, 0.11 and 0.47 mg of gallic acid/g and 78.3, 18.8 and 64.4 mg of rutin/g respectively. Rutin and quercetin were confirmed by HPTLC and HPLC showing well resolved peaks. IC50 values in antioxidant studies were found to be significant with all the extracts. Significant immunomodulatory effect was noticed at 200mg/kg in both models (high antibody titre levels and decrease paw volume after 48 h). Unsatisfactory results were observed with selected cell lines and disc assay.Conclusions: Thus, selected fruits may probably have immunomodulatory potential due to presence of flavonols (rutin and quercetin).

ABSTRACT
Objective: To examine the cytotoxic properties of both the kenaf (Hibiscus cannabinus L.) seed extract and kenaf seed oil on human cervical cancer, human breast cancer, human colon cancer and human lung cancer cell lines.Methods:kenaf seed oil on human cancer cell lines was evaluated by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and sulforhodamine B assays. Cell morphological changes were observed by using an inverted light microscope.Results:The in vitro cytotoxic activity of the kenaf (Hibiscus cannabinus L.) seed extract and cancer cell lines. Morphological alterations in the cell lines after KSE and KSO treatment were observed. KSE and KSO possessed effective cytotoxic activities against all the cell lines been selected.Conclusions:KSE and KSO could be potential sources of natural anti-cancer agents. Further The kenaf seed extract (KSE) exhibited a lower IC50 than kenaf seed oil (KSO) in all of the investigations on using kenaf seeds for anti-proliferative properties are warranted.
