Forensic application of DNA barcoding in the identification of commonly occurring poisonous plants.

Exposure to poisonous plants is hazardous to health; thus, reliable species identification is required to decide the most appropriate treatment. Since ingested plants are too much degraded for visual observation, DNA barcoding can be used as a molecular tool for species identification. Considering the universal primers, PCR and sequencing success rate, and diversity of the poisonous plants, the rbcL DNA marker was selected for molecular identification.

Identification of species adulteration in traded medicinal plant raw drugs using DNA barcoding.

Plants are the major source of therapeutic ingredients in complementary and alternative medicine (CAM). However, species adulteration in traded medicinal plant raw drugs threatens the reliability and safety of CAM. Since morphological features of medicinal plants are often not intact in the raw drugs, DNA barcoding was employed for species identification.

Multi-locus DNA barcoding identifies matK as a suitable marker for species identification in Hibiscus L.

The genus Hibiscus L. includes several taxa of medicinal value and species used for the extraction of natural dyes. These applications require the use of authentic plant materials.

Creation of reference DNA barcode library and authentication of medicinal plant raw drugs used in Ayurvedic medicine.

Background: Ayurveda is a system of traditional medicine that originated in ancient India, and it is still in practice. Medicinal plants are the backbone of Ayurveda, which heavily relies on the plant-derived therapeutics. While Ayurveda is becoming more popular in several countries throughout the World, lack of authenticated medicinal plant raw drugs is a growing concern.

DNA barcode authentication of wood samples of threatened and commercial timber trees within the tropical dry evergreen forest of India.

Background: India is rich with biodiversity, which includes a large number of endemic, rare and threatened plant species. Previous studies have used DNA barcoding to inventory species for applications in biodiversity monitoring, conservation impact assessment, monitoring of illegal trading, authentication of traded medicinal plants etc. This is the first tropical dry evergreen forest (TDEF) barcode study in the World and the first attempt to assemble a reference barcode library for the trees of India as part of a larger project initiated by this research group.
