Plant Secondary Metabolites


Plant Secondary Metabolites

Plant secondary metabolites are organic compounds that are not directly involved in the growth, development, or reproduction of plants. They are produced by plants for various purposes, such as defense against herbivores, attraction of pollinators, and communication with other organisms.

Methods in Molecular Biology

The study of plant secondary metabolites is an important field in molecular biology. It involves the use of various methods and techniques to isolate, identify, and analyze these compounds. The book “Plant Secondary Metabolites” by Harinder P.S. Makkar provides a comprehensive overview of the methods used in this field.

Isolation and Extraction

One of the first steps in studying plant secondary metabolites is the isolation and extraction of these compounds from plant tissues. This can be done using different techniques, such as solvent extraction, steam distillation, and solid-phase extraction.

Identification and Characterization

Once the secondary metabolites are isolated, they need to be identified and characterized. This can be done using various analytical techniques, such as chromatography (e.g., HPLC, GC), spectroscopy (e.g., NMR, mass spectrometry), and bioassays.

Quantification and Analysis

Quantifying the amount of secondary metabolites present in plant samples is also important. This can be done using techniques like spectrophotometry, titration, and enzyme-linked immunosorbent assay (ELISA).

Biological Activities and Applications

Understanding the biological activities and potential applications of plant secondary metabolites is another aspect of their study. These compounds have been found to possess various pharmacological properties, such as antioxidant, antimicrobial, and anticancer activities.
