Cardamom is an important spice, condiment and medicine, and international commodity. DNA-based molecular profiling will be aid in protecting the intellectual property rights of those who trade cardamom on the world market. Commercial cardamom has so far proven recalcitrant to traditional DNA extraction methods. In this paper we report a protocol for the isolation of amplifiable genomic DNA from traded cardamom. The method involves a modified CTAB (hexadecyltrimethylammonium bromide) extraction step, followed by a purification step to remove polysaccharides, proteins, and polyphenols, which are abundant in storage tissue such as cardamom capsules. The yield of DNA was 6–7 μg g−1 tissue. Spectrophotometric and electrophoretic analysis indicated that the isolated DNA was highly pure and of high molecular weight. The isolated DNA could be amplified using different random decamer primers. The protocol has trade implications as it will help in the PCR-based characterisation of traded cardamom. This protocol can be further extended to develop Sequence Characterised Amplified Regions (SCAR) markers for profiling cardamoms. Not Available |
