The tradition of investigating plants and extensively scrutinizing their biologically or pharmacologically active compounds has markedly increased due to their fewer adverse effects compared to synthetic drugs. Through this study, we aim to establish a phytochemical screening and analyze and compare the antioxidant and antimicrobial properties of Artemisia and star anise. The antioxidant characteristics of plant extracts we assessed, the chemical bonds and components composition were analyzed in the sample and further experiments were done to assess the antimicrobial activities. On the results, we found that all the extracts of both the species were very impactful in the inhibition of E. coli, C. Albicans, and S. aureus. However, S. aureus was more sensitive to star anise and E. coli and C. albicans were inhibited better through the alcoholic extracts of Artemisia vulgaris. Star anise has a higher and more effective antioxidant activity against DPPH with a calculated value of 78.3 \% at a concentration of 750 ppm, at a concentration of 500 ppm it was 65.3\% and in the least concentration of 250 ppm, it was 23.3\% compared to Artemisia vulgaris. Additionally, both extracts possessed marked antifungal action.

Objective: Artemisia annua grown in Togo is used as an antimalaria drug. The present study shows a detailed analysis of pharmacognostic evaluation of leaf powder and root that will be used for the purpose of identification, authentication, and consequent standardization. Materials and Methods: Both the leaf and root were evaluated for their macroscopic and microscopic features. The physicochemical parameters of the leaf powder and its phytochemical screening were done based on its total phenols and flavono{\"\i}d content. Artemisinin content was also performed using weigh method after extraction. Results: Physicochemical evaluation yielded water, alcohol, acetone, methanol, chloroform, and petroleum ether soluble extractive values which are 2.25\%, 1.25\%, 4.22\%, 8.12\% and 3.77\% (w/w), respectively. Fluorescence analysis imparted characteristic colors to the leaf powder when observed under visible, UV light 254 and 365 nm. Phytochemical screening of leaf powder showed the presence of alkalo{\"\i}ds, flavono{\"\i}d, and anthracene derivatives. Total phenols and flavono{\"\i}d content were 32.5 {\textpm} 0.67 mEq Gallic Acid/100 mg and 11.3 {\textpm} 1.52. mgEq Quercetin/100 mg, respectively. Artemisinin content value was 0.009\% (w/w). Conclusion: Various pharmacognostic parameters which were evaluated assisted in identification and standardization of A. annua leaf in powder and crude form.
