<strong><em>Flavanoid, steroid, and terpenoid contents of 20 Manokwari medicinal plants were analyzed.  The antioxidant activity, total phenolic contents and antitumor activity of 20 Manokwari medicinal plants were also evaluated. The result shows that 83% positif to flavanoid test, 59% positif to terpenoid test and only 25% positif steroid. Antioxidant activity and total phenolic contents evaluated using Ferric Thiocianate (FTC) and Folin-Ciocalteu methods respectively. Antioxidant activity and total phenolic contents of medicinal plants were extracted by the traditional method, boiling in water and also in 80% methanol. Twenty plants evaluated in both exstracts have significantly varies of antioxidant activities and phenolic contents,  A significant and linier correlation coefficient between the antioxidant activity and the total phenolic content was found in both aqueous (R<sup>2</sup>= 0,77) and methanol (R<sup>2</sup> = 0,85). Antitumor activity was tested using cell maurine P-388 and only 2 of medicinal plants are active to inhibit cell maurine P-388. Comparing extraction efficiency of the two methods, the methanol extracted phenolic compounds more efficiently, and antioxidant activity of the extract was higher.</em></strong>

The study of bioactive molecules of natural origin is a focus of current research. Thymus algeriensis and Artemisia herba-alba are two medicinal plants widely used by the Moroccan population in the traditional treatment of several pathologies linked to inflammation. This study aimed to evaluate the single and combined antioxidant, anti-inflammatory and analgesic effects of the essential oils extracted from these two medicinal plants, and also their potential toxicity. Essential oils were extracted using hydro-distillation in a Clevenger-type apparatus. The antioxidant activity was evaluated by two methods: the scavenging of the free radical DPPH, and the reduction in iron. Anti-inflammatory activity was evaluated by evaluating the edema development induced by carrageenan injecting, while the analgesic power was evaluated according to the number of abdominal contortions induced by the intraperitoneal injection of acetic acid (0.7%). The acute oral toxicity was performed to assess the potential toxicity of the studied EOs, followed by an analysis of the blood biochemical parameters. The results of the two antioxidant tests indicated that our extract mixture exhibits good iron reduction capacity and very interesting DPPH free radical scavenging power, with an IC50 of around 4.38 ± 0.98 μg/mL higher than that of the benchmark antioxidant, BHT. The anti-inflammatory test demonstrated that the mixture administered orally at a dose of 150 mg/kg has a better activity, exceeding that of 1% Diclofenac, with a percentage of maximum inhibition of the edema of 89.99 ± 4.08. The number of cramps in the mice treated with the mixture at a dose of 150 mg/kg is significantly lower (29.80 ± 1.92) than those of the group treated with Tramadol (42.00 ± 2.70), respectively. The toxicity results show no signs of toxicity with an LD50 greater than 150 mg/Kg. These interesting results show that the two plants’ EOs had an important anti-inflammatory, analgesic, and antioxidant activity, and also a powerful synergistic effect, which encourages further in-depth investigations on their pharmacological proprieties.

Objectives: In sub-Saharan Africa, the therapeutic use of medicinal plants is of arousing interest. Reproductive disorders are a public health problem like everywhere else in the world. The population, especially in rural areas, uses medicinal plants for their beneficial effects. In Africa, the population uses these medicinal plants for their healthcare, including solving problems related to childbirth where there is an increase in the number of women known as “traditional birth attendants.” The effects of its medicinal plants relate to the various reproductive processes in women, from pregnancy to induction of labor, elimination of placental retention, and management of postpartum hemorrhage. To contribute to the enhancement of medicinal plants traditionally used in reproductive healthcare in Togo and to make information on their pharmacological effects available to the population, this work focused on the evaluation utero-relaxing and anti-free radical effects of extracts of Desmodium ramosissimum in the female rats of the Wistar strain. Material and Methods: The effects of hydro-ethanolic extracts of leaves, stem barks, and roots of D.ramosissimum were then tested on shreds Myometer of the female rats mounted in an organ vat and the antioxidant activity of these extracts tested was then determined. Results: The results show that hydro-ethanolic extracts from leaves, stem bark, and roots of D.ramosissimum cause a reduction in the frequency of spontaneous contractions of the uterine muscle. This reduction shows that these extracts have relaxing effects on the contraction of this muscle. The leaves extract showed better antioxidant activity compared to other extracts. Conclusion: This antioxidant activity is probably due to the phenolic constituents and its metabolites would be partly responsible for the pharmacological activities of D.ramosissimum. D.ramosissimum could thus be used to reduce uterine contractions in order to avoid Threats of Premature Labor.

Background: There exist natural antioxidants in plants that scavenge harmful free radicals from the body. Free radicals are species of chemical origin with an unpaired electron and play a pivotal role in combating against health-related problems like lung damage, inflammation, and cardiovascular ailments etc. Antioxidants halt the development of these free radicals called the reactive oxygen species either by chelating the trace elements or by enzymes inhibition. Objectives: The aim of present review was to collect information about Pakistani medicinally important plants with the exploration of their antioxidant potential. Methodology: Total 206 papers were looked over, which were obtained from numerous sources like; Google Scholar, Medline, PubMed, Research Gate, Science Direct, Scopus and Web of Science. Results: Overall, 93 plants representing 44 families with potential antioxidant activity reported from Pakistan have been presented in this review. Maximum number of species from Asteracea, Poaceae and Rutaceae familes were scrutinized for their potential antioxidant activity from Pakistan. Conclusion: The present review clearly designates that the presence of phytochemicals and antioxidant activity of medicinal plants from Pakistan vary with the species of the plants and material/extracts used. From this review, it is recommended to perform comprehensive experimental investigations based on toxicology and ethnopharmacology on these precious plants from Pakistan. It will be advantageous in the provision of trustworthy information to patients and determine further innovative compounds for safer and new drugs development with fewer side effects.
