DNA barcoding of ITS and psbA-trnH regions, histochemistry as well as thin layer chromatography (TLC) of Morinda brevipes S.Y. Hu were analyzed. Transverse section of root revealed the presence of cortex, xylem, cork cell, stone cells, and calcium oxalate sandy crystal. The lower epidermis cells showed many stoma in paracytic or inequality type. Spiral vessel and tiny calcium oxalate needle crystal usually appeared in the powder. TLC showed the presence of emodin in M. brevipes. Phytochemical studies revealed the existence of carbohydrates, saponins, tannins, flavones, anthraquinones, alkaloids and volatile oils. The ITS and psbAtrnH sequences were found for the first time which were submitted to NCBI to obtain the GenBank registration number. This study might play an important role in the identification, and utilization of M. brevipes for various purposes.

Chromatographic Profile

The study describes the composition of volatile oils obtained by steam distillation of water fir (Abies alba), pine (Pinus sylvestris), juniper (Juniperus communis), rosemary (Rosmarinus officinalis), sage (Salvia officinalis), and coriander (Coriandrum sativum) using the gas chromatography technique coupled with mass spectrometry (GC-MS). Chromatographic profile revealed the presence of specific components for each studied volatile oil. It noted the presence of a and b- pinene in all volatile oils studied at different concentrations. Volatile oils studied, from green sources and rich in a, b-pinene will be used as raw materials for creating products with anti-inflammatory, antiseptic, bronchodilators properties.
