[Molecular characters of Centella asiatica found with RAPD technology]

Area of Science:

• Molecular Biology
• Plant Genetics
• Biotechnology

Context:

• Centella asiatica, a valuable medicinal herb, faces challenges with adulteration by similar-looking species.
• Accurate identification of Centella asiatica is crucial for its medicinal and commercial applications.

Purpose:

• To develop and validate a DNA-based method for identifying Centella asiatica using Random Amplified Polymorphic DNA (RAPD) technology.
• To establish species-specific genetic markers for Centella asiatica.

Summary:

• Genomic DNA from various Centella asiatica samples was analyzed using optimized RAPD PCR.
• Stable and repeatable specific genetic bands were identified, differentiating Centella asiatica from other plant species like Gynostemma pentaphylum and Tobacco.
• These RAPD markers demonstrated high homogeneity across different Centella asiatica populations.

Impact:

• The established RAPD analysis method provides a reliable tool for authenticating Centella asiatica.
• This technique can effectively distinguish genuine Centella asiatica from adulterants, ensuring quality in herbal products.
• The findings contribute to the conservation and sustainable utilization of Centella asiatica resources.
