RESUMEN
The genus Papaver is highly esteemed in the pharmacy industry, in the culinary field, and as ornamental plants. These plants are also valued in traditional medicine. Among all Papaver species, Papaver somniferum L. (opium poppy) is the most important species in supplying phytochemicals for the formulation of drugs, mainly alkaloids like morphine, codeine, rhoeadine, thebaine, and papaverine. In addition, Papaver plants present other types of phytochemicals, which altogether are responsible for its biological activities. Therefore, this review covers the phytochemical composition of Papaver plants, including alkaloids, phenolic compounds, and essential oils. The traditional uses are reviewed along with their pharmacological activities. Moreover, safety aspects are reported to provide a deep overview of the pharmacology potential of this genus. An updated search was carried out in databases such as Google Scholar, ScienceDirect, and PubMed to retrieve the information. Overall, this genus is a rich source of alkaloids of different types and also contains interesting phenolic compounds, such as anthocyanins, flavonols, and the characteristic indole derivatives nudicaulins. Among other pharmacological properties, numerous preclinical studies have been published about the analgesic, anticancer, antimicrobial, antioxidant, and antidiabetic activities of Papaver plants. Although it highlights the significant impact of this genus for the treatment of a variety of diseases and conditions, as a future prospect, characterization works accompanying preclinical studies are required along with clinical and toxicology studies to establish a correlation between the scientific and traditional knowledge.

Nutraceuticals can serve as an alternative supplement to overcome nutritional deficiency for a healthy lifestyle. They can also play a key role in disease management. To develop carrot nutraceutical products, 64 genotypes from four different continents were evaluated for a range of morpho-nutrition variables. Genetic variability, heritability, strength and direction of association among variables, and direct and indirect relationships among physiochemical and nutritional traits with ß-carotene content were evaluated. Core diameter, foliage weight, root weight and shoulder weight showed significant association with ß-carotene accumulation. Principal component analysis for physiochemical and nutritional assessment divided these genotypes into two distinctive groups, Eastern carrots and Western carrots. Caloric and moisture content had high positive associations with ß-carotene content while carbohydrate content was negatively associated. Five genotypes (T-29, PI 634658, PI 288765, PI 164798, and Ames 25043) with the highest ß-carotene contents were selected for making three nutraceutical supplements (carrot-orange juice, carrot jam and carrot candies). These nutraceutical supplements retained high ß-carotene content coupled with antioxidant properties. Carrot jam (6.5 mg/100 g) and carrot candies (4.8 mg/100 g) had greater concentrations of ß-carotene than carrot-orange juice (1.017 mg/100 g). Carrot jam presented high antioxidant activity with the highest values in T-29 (39% inhibition of oxidation) followed by PI 634658 (37%), PI 164798 (36.5%), Ames 25043 (36%) and PI 288765 (35.5%). These nutraceutical products, with 4-6.5 mg/100 g ß-carotene content, had higher values than the USDA recommended dietary intake of 3-6 mg ß-carotene/day can be recommended for daily use to lower the risk of chronic disease.

Nigella sativa is an extensively utilized herbal medicinal plant. Medicinal utilization of seeds and oil of N. sativa was common among all the ancient medicinal systems. Previously, the vegetative part of the plant was not utilized for pharmaceutical purposes. Therefore, the current study was aimed at determining the potential of the vegetative parts (leaves, branches and stem) of the plant to reduce the pressure on the reproductive part (seeds/oil) and to get a potential alternate source of pharmaceutical materials. The experiment was carried out in split block RCD design. The dried plant was extracted through partitioning method in a series of concentrations ranging from 200-1.562mg/ml in different solvents. Phyto-chemical screening, antibacterial and anti-oxidant assays and GC-MS analysis of the potent extracts were done. The green parts of N. sativa were shown to contain saponins, alkaloids, terpenoids, steroids, cardiac glycosides, tannins, and flavonoids, whereas phloba-tannins were absent. Evaluation of anti-aging properties through antioxidant assays yielded significant results in all the assays. Linoleic acid, palmitic acid, stearic acid, oleic acid and glyceryl linoleate were profiled through GC-MS analysis. Based on these results, it was concluded that the vegetative parts of N. sativa are effective alternatives to the reproductive part/seed for anti-aging and other phytochemicals needed to meet the present day requirements of the pharmaceutical industry.

BACKGROUND: The chief aim of this study was to enlist the ethnopharmacological aspect of mushrooms from four Provinces of Pakistan. Due to the seasonal variation and extreme geographical conditions, Pakistan has great mushroom diversity. Mushrooms have been used by the indigenous people for the treatment of different ailments in many regions of Pakistan. They still depend on the mushrooms for treatment of various ailments. Moreover, mushrooms are used as first aid to treat cold, cough, influenza, asthma, cancer, gastric and hepatic disorders. Traditional uses of medicinal mushrooms lead to the discovery of alternative source of synthetic medicines. This is basically the first quantitative ethnopharmcological documentation of medicinal mushrooms from Pakistan. MATERIALS AND METHOD: Ethnopharmacological information was collected from the 950 informants including male and female. The informative data was based on semi-structured interviews, group discussions, and field visits. Data was analyzed by applying different quantitative indices such as informant consent factor (ICF), Use value (UV), Relative Frequency of Citation (RFC), the Fidelity level (FL) and Jaccard Index (JI). RESULT: Almost 50 mushrooms belonging to 24 families were reported. Most-frequently cited families were Agaricaceae (13 species) and Morchellaceae (5 species). Extract was the common mode of preparation reported (63.33%), followed by Powder (36.67%). Mostly these medicinal mushrooms were present as wild (62.90%), followed by cultivated (37.10%). Among all 11.75% mushrooms were toxic and inedible, 75% were nontoxic, whereas the remaining 13.46% may be toxic or nontoxic because of their dual attitude. New medicinal uses of 23 mushrooms were explored in this study. CONCLUSION: This ethnopharmacological documentation revealed that the mushrooms are still used by natives of rural area in their day-to-day lives. This study provides the basis for the conservation of mushrooms. Mushrooms with high ICF, UV and FL were further used for phytochemical and pharmacological studies. This documentation is baseline information which can be used to develop new mushroom-based medicines.

Matricaria is a widespread genus of flowering plants of the family Asteraceae that grow in temperate regions of Europe, Asia, America and Africa. Some of the species are also naturalized in Australia. Some species of this genus such as Chamomiles are recognized medicinal plants and cultivated in several countries for commercial purposes: to obtain its blue essence, as herbal tea, and for pharmaceutical or cosmeceutical uses. The phytochemical composition of Matricaria spp. includes volatile terpenoids (e.g., α-bisabolol, bisabolol oxide A and B, ß-trans-farnesene and chamazulene), sesquiterpene lactones such as matricin, and phenolic compounds (flavonoids, coumarins and phenolic acids). Their essential oil is obtained from the fresh or dried inflorescences by steam distillation, and additionally cohobation of the remaining water. The volatile composition of the essential oil, especially the content of the valuable components α-bisabolol and chamazulene, depends on the plant part, origin and quality of the source, genetic, and environmental factors. Moreover, other parameters, such as season of harvest and methods of extraction, can affect the extraction yield of the essential oils/extracts, their composition and, therefore, their bioactivity. Due to the importance of this genus and particularly M. recutita (M. chamomilla), this review focus on its cultivation, factor affecting essential oils' composition and their role in traditional medicine, as antibacterial agents and finally as food preservatives.

Plants belonging to the genus Taraxacum have been used in traditional healthcare to treat infectious diseases including food-borne infections. This review aims to summarize the available information on Taraxacum spp., focusing on plant cultivation, ethnomedicinal uses, bioactive phytochemicals, and antimicrobial properties. Phytochemicals present in Taraxacum spp. include sesquiterpene lactones, such as taraxacin, mongolicumin B, and taraxinic acid derivatives; triterpenoids, such as taraxasterol, taraxerol, and officinatrione; and phenolic derivatives, such as hydroxycinnamic acids (chlorogenic, chicoric, and caffeoyltartaric acids), coumarins (aesculin and cichoriin), lignans (mongolicumin A), and taraxacosides. Aqueous and organic extracts of different plant parts exhibit promising in vitro antimicrobial activity relevant for controlling fungi and Gram-positive and Gram-negative bacteria. Therefore, this genus represents a potential source of bioactive phytochemicals with broad-spectrum antimicrobial activity. However, so far, preclinical evidence for these activities has not been fully substantiated by clinical studies. Indeed, clinical evidence for the activity of Taraxacum bioactive compounds is still scant, at least for infectious diseases, and there is limited information on oral bioavailability, pharmacological activities, and safety of Taraxacum products in humans, though their traditional uses would suggest that these plants are safe.

Plants of the genus Zingiber (Family Zingiberaceae) are widely used throughout the world as food and medicinal plants. They represent very popular herbal remedies in various traditional healing systems; in particular, rhizome of Zingiber spp. plants has a long history of ethnobotanical uses because of a plethora of curative properties. Antimicrobial activity of rhizome essential oil has been extensively confirmed in vitro and attributed to its chemical components, mainly consisting of monoterpene and sesquiterpene hydrocarbons such as α-zingiberene, ar-curcumene, ß-bisabolene and ß-sesquiphellandrene. In addition, gingerols have been identified as the major active components in the fresh rhizome, whereas shogaols, dehydrated gingerol derivatives, are the predominant pungent constituents in dried rhizome. Zingiber spp. may thus represent a promising and innovative source of natural alternatives to chemical food preservatives. This approach would meet the increasing concern of consumers aware of the potential health risks associated with the conventional antimicrobial agents in food. This narrative review aims at providing a literature overview on Zingiber spp. plants, their cultivation, traditional uses, phytochemical constituents and biological activities.

Allelopathy is an important phenomenon that modifies the ecosystem. A plant can enhance or reduce the growth of other plant due to the presence of a number of allelochemicals in its different parts. Euphorbia helioscopia and Euphorbia pulcherrima are medicinal plant species. Both these species are collected from wild resources for various purposes. To reduce the pressure on wild population, it is important to bring them into cultivation. Therefore, the allelopathic effects of E. helioscopia and E. pulcherrima on the growth of lettuce seeds were studied. Three different concentrations (2%, 4% and 6%) of five different solvents (methanol, acetone, ethyl acetate, n-hexane and distilled water) were used to estimate the allelopathic potential of the above-mentioned Euphorbia species. Results indicated a non-significant growth inhibitory effect of both plants on lettuce seeds. Different extracts reduced the growth of test plant to some extent but this inhibition was not significant. From the observed results, it was concluded that the studied Euphorbia species, being medicinally important crops, can be introduced as intercrop with other cash crops.
