In this study, GC-MS analysis has shown that whole plant butanol fraction of rheum ribes (WBFRR) comprises of 21 compounds which exhibited anticancer (MCF-7) activity having IC50 value of 36.01± 0.26. MTT assay (MCF-7), Oxidative Burst assay using chemiluminescence technique, and B-Hatching techniques were the methods used for anticancer MCF-7, anti-inflammatory, and Brine Shrimp Lethality Assay (BSLA). GC-MS was used for structural elucidation. Whole plant methanol extract of rheum ribes (WMERR), whole plant n-hexane fraction of rheum ribes (WHFRR), and whole plant aqueous fraction of rheum ribes (WAFRR) were inactive against anticancer (MCF-7) cell line. Whole plant methanol extract of rheum ribes (WMERR), whole plant aqueous fraction of rheum ribes (WAFRR) and whole plant butanol fraction of rheum ribes (WBFRR) showed anti-inflammatory activity on ROS having IC50 value of 23.2±1.9, 24.2±2.7 and 12.0±0.6. Whole plant butanol fraction of rheum ribes (WBFRR) showed Brine Shrimp Lethality with LD50 693.302 while whole plant methanol extract of rheum ribes (WMERR) and whole plant aqueous fraction of rheum ribes (WAFRR) showed high lethality at highest concentration. This study revealed that whole plant butanol fraction of rheum ribes (WBFRR) exhibited significant anticancer (MCF-7) activity. In the near future, the constituent of whole plant butanol fraction of rheum ribes (WBFRR) can be the alternative drug against MCF-7 cell line with least toxicity and side effects.

Astragalus Stocksii a local flowering plant found in Hana Valley, Quetta Pakistan, used as home medicinal plant form many years. It is an encouraging source of bioactive compounds and has been conventionally manipulated for the coverage of several diseases. The present study based on the evaluation of phenolics, antioxidants and anti-inflammatory activities of Astragalus Stocksii by using three different solvents, i.e. ;acetone, ethanol and methanol. The results showed that extraction yield depends upon the type of the solvents used for extraction. Among these, extraction in methanol has the highest phenolic contents (10.086±0.08mgCE/g DW),total antioxidant capacity (TAC, IC50=14.50±0.01 μg/mL,phospho-molibdenummethod,IC50=66.62± 0.03 μg/mL by DPPH method)and high anti-inflammatory activity (IC50=75.0 ±2.5 μg/mL, oxidative burst assay). These results indicate that methanol is the best solvent for extraction of phenolic and antioxidants in Astragalus Stocksii. The high results of anti-inflammatory for Astragalus Stocksii suggests its use inpharmaceutical and nutraceutical industries.
