 Plants are an excellent source of phenolic compounds, which are among the most important antioxidant substances. The antioxidant properties of medicinal plants have prompted researchers to use them in the food, health and pharmaceutical industries.

 The purpose of the present study is to investigate the antioxidant properties of the methanol extract of the medicinal plants of Salsola rigida (Salsola orientalis) and wheat. The aerial parts of these plants were dried and ground. Then plant samples were prepared using homogenized methanol. Finally, the total antioxidant capacity of the mentioned plants was evaluated using ferric iron reducing antioxidant power (FRAP).

 The results showed that the total antioxidant capacity for Salsola rigida and wheat was 0.77 and 2.20 Fe2+ mmol L-1, respectively. Based on our findings, wheat showed strong antioxidant activity and S. rigida showed little antioxidant capacity.

 It is recommended to use the medicinal plants of S.rigida and wheat due to antioxidant effects against free radicals. Antioxidant medicines or supplements can be produced from the mentioned plants.

In many countries, cancer is the second leading cause of fatality after cardiovascular disease. Cancer is a growing problem worldwide and is one of the most important reasons for fatality in human societies. The problems of chemotherapy and radiation therapy and the many side effects that result from their use for the patient, as well as the resistance of cancer cells to common treatments, have led researchers to new drugs with greater effectiveness and less toxicity. One of the best ways to reduce the risk of cancer is to use natural materials. The purpose of this study is the effect of medicinal herbs on cancer in Iran. This study aims to search the types of herbs that are beneficial for the health of body tissues concerning cancer, in order to be able to provide a suitable way to prevent the types of cancer that are more common in humans which has become a major problem in the medical world. In the treatment of cancers from medicinal plants such as Trachyspermum ammi, Crocus sativus, Silybum marianum, Nigella sativa, Cornus mas, Aloe vera, Zingiber officinale, Urtica dioica, Allium cepa, Glycyrrhiza glabra, Peganum harmala, Plantago ovate, Thymus vulgaris, and Elkhorn fern. Some of the most important traditional natural anti-cancer substances include Catharanthus roseus, Podophyllum peltatum, Combreturn cafrum, Campetotheca acuminate, and Brucea antidysenterica. The use of herbal medicines with anti-cancer properties can be used as a substitute or supplement to chemical drugs in treating cancers. Many unique plant species need to be further studied to find anti-cancer compounds.

Medicinal plants are useful in perfumery, pharmaceutical, and food industries. Recognition of compounds and functional groups of these plants helps to more understand their structure, medicinal and therapeutic applications. Essential oils and extracts are used to recognition structure. One of these spectroscopic methods for identifying functional groups in medicinal plants is Fourier-transform infrared spectroscopy (FTIR) spectroscopy. This study aimed to identify the functional groups of medicinal plants of Oliveria decumbent native to Ilam by the FTIR method. Based on the results obtained, it was determined that this plant includes 15 spectra including groups O-H, C-H, C = O, C = C, N-O, C-O, C-N, and C-I. So, the present study concluded that the Oliveria decumbens possessed strong functional groups.
