One of the most ancient human medical techniques is the use of plants to treat, prevent, and cure diseases. These plants can manufacture a wide variety of natural chemicals. The present study aimed to evaluate the antibacterial activity and antioxidant capacity of ethanolic extract of four plant species (Zizyphus lotus, Lavandula dentata, Ruta graveolens, and Dodonaea viscosa). Using disc diffusion and serial dilution procedures, the antibacterial abilities of these EtPEs were evaluated. The antioxidant properties were evaluated by the FRAP method and the Folin-Ciocalteu technique was used to measure the total phenolic content. Different plant extracts showed different inhibitory effects on the tested bacteria in a dose-dependent manner. Among the tested plant extracts, D. viscose exhibited the highest antibacterial activity against P. vulgaris and S. aureus, with a minimum inhibitory concentration (MIC) value of 0.5 mg/ml. On the other hand, R. graveolens displayed the highest quantity of phenolic compounds and demonstrated the highest antioxidant activity. Notably, there was a positive correlation observed between the antioxidant activity of the plant extracts and their total phenolic content. In conclusion, the findings of this study suggest that the tested plant extracts hold potential as promising sources of natural antibacterial and antioxidant agents.

Background: Tanacetum parthenium (L.) Sch Bip known as {\textquotedblleft}santa mar{\'\i}a{\textquotedblright} (Asteraceae family) is used in Peru for inflammatory diseases and also in colic, stomachache, headaches, diarrhea, among other. Objective: The aim was to determine the antioxidant profile, and analgesic effect of ethanolic extract of flowers and leaves of T. parthenium Material and Methods: Leaves and flowers of T. parthenium were soaked in 96\% ethanol and the obtained extract was analyzed using chemical reactions for identifying each secondary metabolite, 2,2-Diphenyl-1-picrylhydrazyl (DPPH) was used to determine the antioxidant capacity, and the antinociceptive effect was determined by using tail flick method. Results: Qualitative phytochemical study indicates the presence phenolic compounds, alkaloids, flavonoids, saponins and steroids in both extracts. In DPPH assay IC50 showed in leaves and flowers extract 452.10 {\textpm} 10.2 μg/mL and 270.70 {\textpm} 20.6 μg/mL respectively. The antinociceptive effect was better in leaves at doses 300 mg/ Kg than flower extract. Conclusions: The ethanolic extract of flowers of T. parthenium showed a high antioxidant activity and antinociceptive effect in mice.

Objective: This work aims to find a new treatment based on the development of safe natural anti-diabetic mixtures. It assesses the hypoglycemic activity of natural mixtures and determines whether there are any negative side effects from the interaction of the herbs and the herbs. Methods: Six natural mixtures were tested for anti-diabetic activity, which was confirmed by a pathological histological examination. We performed a GC-MS analysis on active mixtures 1 and 2, yielding 54 and 38 compounds, respectively. The major compounds were Gingerol, Butan-2-one and 4-(3-hydroxy-2-methoxyphenyl) (97 and 64.02 per cent). Results: Among the six samples, the organic extract of mixture 1 and 2 showed a significant reduction in BGL compared to the standard drug glimepiride at a dose of 10 mg/kg ip and demonstrated a beneficial effect on renal function in alloxan-induced diabetic mice. These results were confirmed by a histopathological study which revealed that both mixture 1 and mixture 2 had decreased morphological and ultrastructural changes in the triggered liver. Docking of cuminaldehyde, Gingerol and α-Copaenin at the active site of human pancreatic enzymes α-amylase and aldol reductase revealed that these compounds had binding affinity at the active site of the enzymes. Conclusion: Our results revealed the anti-diabetic activity of non-polar mixtures consisting of long chain hydrocarbons, oils and non-polar components, thus suggesting that the herbal formulation is safe and effective for the treatment and complication of type 2 diabetes.

Cancer is actually a group of many related diseases that all have to do with cells. Cancer cells are characterized by unregulated growth, as well as insufficient and inappropriate vascular supply. Moreover, a core of cells was subjected to micro environmental stress conditions, and has decreased apoptotic potential through genetic alterations, thereby resulting in resistance to apoptosis. Cancer is one of the major causes of death worldwide where the number of cancer patients is in continuous rise. Cancer is a major public problem whose estimated worldwide new incidence is about 6 million cases per year. It is the second major cause of deaths after cardiovascular diseases. Chemotherapy remains the principal mode of treatment for various cancers. A number of synthetic anticancer drugs are available in practice, but the side effects and the drug interactions are major drawbacks in its clinical utility. Most of the currently used chemotherapy drugs for cancers are known to develop resistance, exhibit non-selective toxicity against normal cells and restrict by dose-limiting side effects. Hence, cancer treatment and development of drugs for this disease remains a major clinical challenge. On the other hand, plants are an exceptionally viable source of biologically active natural products which may serve as commercially significant entities in themselves or which may provide lead structures for the development of modified derivatives possessing enhanced activity and/or reduced toxicity in traeatment of cancer. Herbal medicines are now attracting attention as potential sources of anticancer agents and are widely used due to availability of the materials, affordability, relatively cheap and little or no side effects, wide applicability and therapeutic efficacy which in turn has accelerated the scientific research. For these reasons, World Health Organization (WHO) supports the use of traditional medicines which are efficacious and non toxic. In this review we have summarized few plants having anticancer activity.
