Evaluation of Iraqi medicinal plants is very crucial to help people avoid the use of herbs without prior knowledge which results in many side effects and sometimes even leads to death. The plant constituents vary according to season, weather and type of soil, therefore it is necessary to evaluate the chemical constituents and determine the time of collection of medicinal plants. In this research evaluation of the medicinal plant Calendula officinal grown in Iraq was performed by measuring the quantity of hyperoside found in the plant together with macroscopical and microscopical evaluation of the plant.

The objective of this work was to collect information on the curative use of plants in the municipality of Teziutlán, Puebla through semi-structured interviews. Thus, 78 plants used for medicinal purposes were identified, of which 40 are native to Mexico and 38 introduced; The value of use (UV) of each one and the Informant's Consensus Factor (FCI) of 10 categories of diseases were calculated. The five most frequently used plants are Ruta chalepensisL., Rosmarinus officinalis, Arnica montana, Loeselia mexicana(Lam.) Brandegee and Sambucus ceruleavar., Neomexicana, which underwent a chemical and pharmacological review. On the other hand, the most frequent preparations are infusion and decoction, using mainly leaves (49.34%) and flowers (19.51%). It is concluded that the inhabitants of Teziutlán have a fairly homogeneous ethnomedical knowledge, setting the standard for research on its pharmacological properties.

Cancer is an abnormal and uncontrolled growth of cells that spreads through cell division. There are different types of medicines available to treat cancers, but no drug is found to be fully effective and safe for humans. The major problem involved in the cancer treatments is the toxicity of the established drug and their side effects. Medicinal plants are used as folk medicines in Asian and African populations for thousands of years. 60% of the drugs for treating cancer are derived from plants. More than 3000 plants have anticancer activity. The present review aims at the study of a broad spectrum survey of plants having anticancer components for different type of cancers. This article consists of 364 medicinal plants and their different parts as potential Source of Anticancer Agents.

Barleria terminalis Nees and Calacanthus grandiflorus (Dalzell) Radlk. are endemic medicinal plants of the Western Ghats of India. The aim of the present research work was to investigate phytochemical profile, potent bioactives using RP-HPLC, LC-MS and GC-MS and to evaluate their bioactivities. Acetone was found to be the best extraction medium for separating phytochemicals. Similarly, acetone and methanol extracts exhibited potential antioxidant properties. Ethanol extract of B. terminalis stem showed potent acetylcholinesterase (AChE) (89.10 ± 0.26%) inhibitory activity. Inhibition of α-amylase (36.96 ± 2.96%) activity was observed the best in ethanol extract of B. terminalis leaves and α-glucosidase inhibitory activity (94.33 ± 0.73%) in ethanol extract of C. grandiflorus stem. RP-HPLC analysis confirmed the presence of several phenolic compounds (gallic acid, hydroxybenzoic acid, vanillic acid, chlorogenic acid and coumaric acid) and phenylethanoid glycoside (verbascoside). The highest phenolics content were observed in B. terminalis (GA (4.17 ± 0.002), HBA (3.88 ± 0.001), VA (4.54 ± 0.001), CHLA (0.55 ± 0.004) mg/g DW, respectively). Similarly, LC-MS and GC-MS revealed the presence of phenolics, glycosides, terpenes, steroids, fatty acids, etc. Moreover, positive correlation between studied phytochemicals and antioxidants was observed in principal component analysis. Based on the present investigation, we conclude that B. terminalis and C. grandiflorus can be further explored for their active principles particularly, phenylethanoid glycosides and iridoids and their use in drug industry for pharmaceutical purposes.
