Volatile oils, also known as essential oils, are complex mixtures of volatile, aromatic compounds derived from plants. These oils evaporate readily at room temperature and are responsible for the fragrance and flavor of many plants. They are typically extracted by distillation, expression, or solvent extraction. Classification of Volatile Oils Volatile oils can be classified based … Read more
Definition Secondary metabolites are organic compounds produced by plants, bacteria, fungi, and animals that are not directly involved in the normal growth, development, or reproduction of the organism. Unlike primary metabolites (such as amino acids, nucleotides, and carbohydrates), which are essential for the basic metabolic processes of life, secondary metabolites often play crucial roles in … Read more
Pharmacognosy is the study of medicinal drugs derived from plants and other natural sources. Plant tissue culture has become a vital tool in pharmacognosy, offering numerous applications in the discovery, production, and study of medicinal compounds. Here is a detailed note on the various applications of plant tissue culture in pharmacognosy: Â 1. Production of Secondary … Read more
Introduction to Chemical Classification in Pharmacognosy: Chemical classification in pharmacognosy categorizes drugs based on their chemical composition, particularly focusing on compounds derived from natural sources such as plants, animals, and minerals. This classification system is crucial for understanding the bioactive constituents of medicinal substances and their pharmacological effects. Key Criteria for Chemical Classification: Chemical classification … Read more
Terpenoids, also known as isoprenoids, constitute a diverse and extensive class of natural compounds derived from isoprene units consisting of five carbon atoms each. These organic compounds are essential in various living organisms, including plants, microorganisms, and animals. Terpenoids are characterized by their structural diversity, with numerous variations resulting from the arrangement of isoprene building … Read more
