Abstract:
Sophora flavescens has anti-inflammatory, analgesic, antibacterial, antiviral, and anti-tumor properties due to its active compounds, including alkaloids and flavonoids. Exploring the biosynthetic regulation mechanism of these compounds is crucial. Here, we identified 227 flavonoids and 55 alkaloids among five tissues (roots, stems, leaves, flowers, and pods) using wide-targeted metabolomics. Flavonoids were predominantly in roots, whereas alkaloids were primarily in roots and flowers. RNA sequencing revealed 18,488 differentially expressed genes (DEGs) in non-root tissues compared to roots. T

Abstract:
Herbs have been an integral part of human life for ages. Modern allopathic drugs had an upper hand over traditional medicine in the past century due to their mounting inefficacy, resistance, cost, and adverse effects that have led to the reclaim of herbs once again. Herbs holistically confer biological activity due to the presence of phytochemicals, which are classified broadly as carbohydrates, lipids, terpenoids, alkaloids, polyphenols, and essential and volatile oils. In this, polyphenols are a vast group further comprising flavonoids, phenolic acid, stilbenoids, tannins, lignans, xanthones, quinones, coumarins, phenylpropanoids, and benzofurans. Of this, flavonoids are hydroxylated phenolic substances with basic C6-C3-C6 rings substitution, which gives rise to a series of compounds namely, flavonols, flavanones, flavones, anthocyanidins, flavanonols, chalcones, isoflavones, and flavanols. They are abundantly found in vegetables and fruits and exhibit antioxidant, free-radical scavenging activity, anti-cancer, cardioprotective, anti-diabetic, anti-inflammatory, anti-allergic, and anti-microbial action. The advent of modern molecular techniques and computational methodologies has thrown light on the molecular mechanism of action of these flavonoids, which was otherwise obscure. Hence this chapter aims to review the types, sources, chemistry, and molecular mechanisms of action of the various phytomolecules of flavonoid groups.

Abstract:
Secondary metabolites (SMs) are natural compounds produced mainly by bacteria, fungi, and plants. They are low molecular weight compounds that have a wide range of chemical structures and biological functions. Secondary metabolites are so named because, unlike primary metabolites such as lipids, amino acids, carbohydrates, and nucleic acids, their synthesis is not required for the organism’s development and reproduction. Today, the production of secondary metabolites is an important area of research for organic chemists, molecular biologists, and bioinformaticians. In this research, two types of secondary metabolites produced by plants, such as alkaloids and flavonoids, were studied and information was collected on the types of compounds, structures, biological activities, and commercial applications of these two types of secondary metabolites.

Abstract:
Semecarpus anacardium is classified in Ayurveda under the category of toxic plants. However, this toxic plant is reported to possess anti-inflammatory activity, anti-arthritic effect, antioxidant activity, antimicrobial activity, anti- carcinogenic activity, hypoglycemic activity, cardioprotective, hepatoprotective, neuroprotective, and hypolipidemic activity etc. All these activities are attributed to its various constituents like phenolic compounds, flavonoids, carbohydrates, alkaloids, steroids, etc. In Ayurveda, a series of pharmaceutical procedures which converts a poisonous drug into a safe and therapeutically effective medicine is termed as Shodhana. Shodhana improves the yield, decreases the phenolic and flavonoid content; and converts toxic urushiol into nontoxic anacardol derivative thereby reducing toxicity of nuts of Semecarpus anacardium. There are reports of alteration in pharmacology and phytochemistry of nuts of Semecarpus anacardium due to Shodhana.

Abstract:
Objective: An essential first step in discovering the bioactive elements present in medicinal plants that can then result in the discovery and creation of novel medications is the preliminary screening of phytochemicals. The principal phytoconstituents of five medicinal plants from different families were chosen for the current study, and their presence was connected to the bioactivities of the plants. Methods: Using standard techniques, a phytochemical screening of five chosen medicinal plants was performed to check for the presence of flavonoids, alkaloids, carbohydrates, phenols, glycosides, proteins, saponins, phenols. Result: As a result, phenols were present in every leaf extract from the chosen five medicinal plants. Furthermore, all of the selected plants with the exception of Ruellia prostrata contained flavonoids. All plants, with the exception of Pongamia pinnata, contained saponins. Alkaloids, cardiac glycosides, carbohydrates and steroids were present in all the selected plants except Ruellia prostrata, Erythrina indica and Hygrophila auriculata. However, none of the five medicinal plants we chose contained any proteins and terpenoids. Conclusion: According to the study, Ruellia prostrata has the least number of phytochemical components, whereas Pongamia pinnata and Aegle marmelos leaf extract have the most. Secondary metabolites like phenols, saponins and flavonoids which are virtually present in all five medicinal plants, have been shown to act as a capping, reducing, and bio-reducers for the formation of metal and metal oxide nanoparticles.

Abstract:
Given the potential adverse effects of chemical drugs, utilizing natural products with diverse therapeutic and antimicrobial compounds is advisable. Countries can use indigenous flora from their regions in vegetation for medicinal purposes. Several nations exhibit distinctive indigenous flora owing to their geographic positioning and climatic conditions. These plants have been the subject of our research, which has explored their antimicrobial properties against fungi, parasites, bacteria, and viruses. Studies have investigated the therapeutic and antimicrobial effects of plants and their bioactive compounds, such as alkaloids, flavonoids, and terpenoids. Among them are alkaloids, a diverse class of naturally occurring chemicals, such as tropanes, terpenoids, and steroids. Some of these medicinal plants have been found to possess antioxidant and anti-inflammatory properties in addition to their antimicrobial effects. This chapter explores the antimicrobial potential of alkaloids found in medicinal plants.

Abstract:
Influenza is an acute viral infection of the respiratory tract caused by the Alphainfluenzavirus whose subtypes were responsible for historical pandemics. Recently, the coronavirus SARS-CoV-2 has also affected the world, causing acute respiratory syndrome, thus rendering the search for anti-influenza and anti-SARS-CoV-2 compounds an urgent task. Plants of the genus Siparuna are used in Brazilian folk medicine for treating colds, fever, headaches, and rheumatic pain as well as gastrointestinal disorders. S. apiosyce (“Limão Bravo”) is mentioned in the first Brazilian Pharmacopeia due to its importance as an ingredient in syrup and cough drops. Alkaloids, methylated and glycosylated flavonoids stand out as secondary metabolites described for these species, being also well described in the literature for their antiviral activity. During our investigation of Brazilian plants active against viral infections, the anti-influenza activity of five Amazonian Siparuna (S. cristata, S. decipiens, S. glycycarpa, S. reginae and S. sarmentosa) were investigated, showing the n-butanol extracts of S. glycycarpa and S. sarmentosa as the most active. Dereplication of these extracts pointed alkaloids, O- and C-glycosylated flavonoids as well as dihydrochalcones and a procyanidin dimer as potential active metabolites. On the other hand, the dichloromethane extract from S. cristata containing methylated flavonoids was able to inhibit the in vitro replication of SARS-CoV-2, where it was shown that retusin and kumatakenin presented a higher selectivity index than lopinavir/ritonavir and chloroquine controls. Further in-silico studies showed the potential interaction between these flavonoids and the virus proteases 3CLpro and PLpro. Here we highlight the possible application of compounds isolated from Siparuna species as antiviral agents.

Abstract:
The Cordiaceae family consists of a fascinating group of flowering plants native to tropical and subtropical regions around the world. Although they were once classified as a subfamily within the larger Boraginaceae family, recent phylogenetic studies have recognized them as a distinct family with unique characteristics. This family includes around 350 species, spread across two recognized genera: Cordia and Varronia (Miller and Gottschling 2007). Some members contain phenolic compounds, flavonoids, triterpenoids, alkaloids, and essential oils.
