A suitable emulgel formulation of piroxicam was prepared and its percutaneous permeation was investigated using Wistar rat skin and diffusion cell technique. The concentrations of the drug in receptor phase of diffusion cells were measured using HPLC method. The effect of three types of penetration enhancers (Myrj 52, cineol and Transcutol P) with different concentrations on transdermal permeat...

The composition of leaf and rhizome essential oils of Alpinia smithiae that grow wild in the Western Ghats of Kerala (South India) was analysed by gas chromatography. The major components were beta-caryophyllene, sabinene, myrcene and 1,8-cineole in both samples, but variation in the yield of oil as well as the major components between the two plant parts was observed.

Immature Litsea mollis fruits (ILMFs) are widely used as cold appetizers and seasonings in China. The free bound volatile components of ILMFs from five distinct regions China were determined by gas chromatography-mass spectrometry (GC-MS) combined with headspace solid phase microextraction (SPME) the present work. results reveal sixty six free-form volatiles fifty two bound-form terpene hydroca...

Conamomum vietnamense , a new species of Zingiberaceae family, has been discovered and described from Tay Nguyen (Central Highlands, Vietnam) in 2022. The present study the preparation essential oil leaves rhizomes plant by hydrodistillation process. Then, chemical composition these oils was analyzed Gas Chromatography-Mass Spectrometry (GC-MS), which indicated that limonene (18.74 26.20%) euca...

The change of essential oil ratios and components five different basil genotypes harvested at times (00:00, 06:00, 12:00, 18:00) in day was investigated. Plants were grown under the field conditions oils plants extracted by hydro-distillation method. Identification performed GC-MS. It G5 genotype that had highest content all plant parts, regardless time day. (2.8%) obtained from dry leaves samp...

Background & Aim: The genus Tanacetum L. belongs to the family Asteraceae and tribe Anthemideae. According to the recent findings the number of Tanacetum species in Iran is 36, of which 12 are endemic. In this study the essential oil composition of Tanacetum chiliophyllum var. oligocephalum was investigated for the first time.   Experimental: The plant was c...

Terpenes and terpenoids encompass one of the most extensive valuable classes secondary metabolites. Their ten-carbon-containing oxygenated representatives, monoterpenoids, are main components plant essential oils, being widely exploited in cosmetic, pharmaceutical, food industrial areas. Due to its widespread use, it is crucial investigate their environmental distribution. Thus, new water solub...
