Introduction Volatile oils, also known as essential oils, are concentrated hydrophobic liquids containing volatile aroma compounds extracted from plants. They are termed “volatile” due to their ability to evaporate at room temperature, thus readily releasing their aromatic components into the air. These oils are responsible for the characteristic fragrances of …

Volatile Oils: Definition, Classification, Properties, and Tests for Identification
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 …
 Introduction to Secondary Metabolites: Definition and Classification
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 …
Applications of Plant Tissue Culture in Pharmacognosy
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.
