Helichrysum excisum

Lourens et al. (2004) evaluated the in vitro biological activity and chemical composition of the EOs of four indigenous South African Helichrysum species (Asteraceae), such as Helichrysum dasyanthum, Helichrysum felinum (strawberry everlasting), Helichrysum excisum, and. Helichrysum petiolare (licorice plant). An interesting anti-inflammatory effect could be observed in the lipooxy-genase-5 assay at doses between 25 and 32 pg/mL. Analysis of the chemical composition showed that the EOs comprise mainly monoterpenes such as a-pinene, 1,8-cineole, andp-cymene, only the oil of Helichrysum felinum was dominated by sesquiterpenes in low concentrations with P-caryo-phyllene as main compound on top. 

Helichrysum (strawflower, Asteraceae) species are traditionally used for the treatment of wounds, infections, and respiratory conditions (Lourens et al., 2004). In the inflammatory process free radicals adsorb on the phagocyte cells, so the antioxidative activity of the extract and the EOs of different Helichrysum species were examined. Therefore, the plant material of Helichrysum dasyanthum, Helichrysum excisum, and Helichrysum petiolare were collected and the EO obtained by hydrodistillation. The GC-MS analysis showed that 1,8-cineole (20-34%), p-cymene (6-10%), and a-pinene (3-17%) are principal components of the EO. The EOs of all three different species show an antioxidative activity in the DPPH assay, bnt it has to be noticed that the extract, which was obtained by a cold...
