Ranarivelo, 2017 1 ABSTRACT Psorospermum belongs to the tribe Vismieae (Hypericaceae). Morphologically, Psorospermum is very similar to Harungana, which also belongs to Vismieae along with another genus, Vismia. Interestingly, Harungana occurs in both Madagascar and mainland Africa, as does Psorospermum; Vismia occurs in both Africa and the New World. However, the phylogeny of the tribe and the relationship between the three genera are uncertain.

Global and state rank: G5/S3 Recognition: H. gentianoides is an annual species Other common names: orange-grass, orange-grass St. ranging from 1-2 dm in height or more, with an erect, John’s-wort central stem that terminates in a number of slender, strongly ascending branches. When crushed, the plant Family: Clusiaceae (St. John’s-wort family); also produces a faint, citrus-like fragrance (which has known as the Guttiferae, and sometimes placed in the also been described as a peach-like odor), as indicated separate family Hypericaceae, similarly long known as by some of the common names for this species.

We examined the possible antigenotoxic/genotoxic properties of methanolic extract of H. olympicum subsp. olympicum (HOE) on human lymphocytes by employing sister chromatid exchange, micronucleus and comet assay and analyzed its chemical composition by GCxGC-TOF/MS. The anti-growth activity against MCF-7 and MDA-MB-231 cell lines was assessed by using the ATP viability assay. Cell death mode was investigated with fluorescence staining and ELISA assays. The major components of the flower and trunk were determined as eicosane, heptacosane, 2-propen-1-ol, hexahydrofarnesyl acetone and α-muurolene. HOE caused significant DNA damage at selected doses (250–750 µg/ml) while chromosomal damage was observed at higher concentrations (500 and 750 µg/ml). HOE demonstrated anti-growth activity in a dose-dependent manner between 3.13–100 µg/ml.
