Chemical composition in two species of Verbascum collected from natural habitats, southern Iran

Journal of herbal Drugs, Vol. 4, No, 3: 127-132


Background & Aim: In the present research, we investigated phytochemical characteristics of two important species of Verbascum genus. Enormous reconnaissance and field surveys were conducted to identify the most
important natural habitats of Verbascum species in Kohgiluyeh va Buyerahmad province, southern Iran.

Experimental: The aerial parts of Verbascum songaricum and V. cheirantifolium were collected at flowering stage in July 2011. The extraction was conducted by digestion method, and then to analysis and identify extracts used by GC-MS. Totally, the number of 60 and 52 compositions from different V. songaricum and V. cheirantifolium extracts identified, respectively. In order to compare different compositions present in parts between both species, first compositions were classified into six functional groups (alcohol, amin, ester, hydrocarbon, ketone, and acid), then these groups were analyzed.
Results & Discussion: Results indicated that there were significant differences among various parts of flowers, leaves, and stems in both species in terms of alcohol, amin, ester, hydrocarbon, and ketone. Given that enhancement of medicinal qualitative and quantitative yields not only depends on ecological conditions, but also varies in respect to various extractions methods, etc. In addition, this is associated o plant genetically
architecture. Results obtained from V. songaricum and V. cheirantifolium showed that although both species grow close together.
Recommended applications/industries: The leaves of species of Verbascum have the higher chemical variation than other plant organs such as flower and stem.
