“…p-Cymene was the only phenolic compound identified, while oxygenated aliphatic hydrocarbons and sequiterpene hydrocarbons were present in trace amounts. Components such as limonene, octyl acetate, bornyl acetate were also reported from the oils of H. candolleanum and H. siamicum [5,6]. Further octyl acetate was a prominent component in H. persicum, H. rechingeri, H. transcaucasicum, H. crenatifolium, H. platytanium and H. sphondylium L. subsp.…”

“…The seed oil of H. candicans, H. lehmannianum, H. ponticum and H. aconitifolium have been evaluated for various ailments [3,4]. The extraction of the seed oils and their chemical compositions were reported for H. condolleanum and H. siamicum [5,6]. Due to the absence of any such studies in H. rigens, the present study was undertaken to evaluate the chemical composition of the essential oil and its antimicrobial activity on selected pathogenic bacterial strains.…”

The essential oil was extracted from the seeds of Heracleum rigens by hydrodistillation and a total of twenty compounds accounting for 98.5% of the total oil composition were identified. Physicochemical properties and chemical composition of the oil was determined by a combination GC/FID and GC/MS analysis. The major compounds identified were bornyl acetate (51.2%), α-pinene (22.6%), limonene (9.62%), octyl acetate (3.94%), p-cymene (2.85%) and γ-terpinene (1.93%). The antimicrobial activity of the oil was screened by the disc diffusion method against nine pathogenic bacterial strains. Maximum antimicrobial activity was noted against Klebsiella pneumonia and Bacillus subtillis. This investigation corroborates the traditional claim of H. rigens as an effective antimicrobial agent.

Chemical composition, antibacterial and antifungal activities of essential oil from Heracleum Siamicum Craib

2011

View full text Add to dashboard Cite

Heracleum siamicum Craib (Apiaceae), is an important herbal species having wide application in food flavoring processes. The flat-oval shaped fruit of H. siamicum Craib from North Thailand was hydrodistilled, and the chemical composition of the essential oil was analyzed by GC and GC-MS. The essential oil yield based on dried plant material was 1.25%, and twenty-five compounds (corresponding to 97.69% of the total weight) were identified. The main components were: n-octyl acetate (65.30%), o-cymene (10.35%), limonene (7.52%), d-2-carene (6.87%), cis-thujone (1.92%), isobornyl acetate (0.94%), n-octanol (0.73%), 1,8-cineol (0.62%), n-tridecanol (0.44%), and safrole (0.37%). H. siamicum essential oil demonstrated bactericidal and fungicidal activity against five bacterial strains and two fungal strains, as evaluated using agar diffusion in terms of the minimum inhibitory concentration.

“…They are reported to be effective in indigestion, sunburn, skin diseases, and external tumours (Heywood, 1971). Many studies reported on the biological activities and essential oil composition of the genus Heracleum (Ergene et al, 2006;John et al, 2007). As part of our on-going studies on the genus Heracleum from Western Ghats of India, we now report on the composition of the volatile oils of the fruits of H. aquilegifolium for the fi rst time, together with their antioxidant properties.…”

The fruits of Heracleum aquilegifolium Wight (Apiaceae) were collected from Western Ghats of the Indian Peninsula. The essential oils were extracted by hydrodistillation. The chemical composition of the essential oils was analysed by gas chromatography and gas chromatography-mass spectrometry (GC-MS). -Pinene (22.3%), 1,8-cineole (20.3%), and -phellandrene (12.4%) were the main components of H. aquilegifolium fruit oils. The antioxidant properties of essential oils of H. aquilegifolium were examined by different procedures namely reducing power ability, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, nitric oxide radical scavenging activity, hydrogen peroxide scavenging activity, hydroxyl radical scavenging activity, superoxide anion scavenging activity, and metal chelating activity. The antioxidant activities were compared with those of synthetic antioxidants and standard drugs such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), ascorbic acid, -tocopherol, curcumin, and quercetin. The study confi rmed the possible antioxidant potential of essential oils tested with various in vitro antioxidant methods. The presence of monoterpenes in combination with other components in the oils could be responsible for the activity.
