The composition of the essential oil hydrodistilled from the aerial parts of the 'resurrection plant' Myrothamnus moschatus (Baillon) Niedenzu endemic to Madagascar was investigated for the first time by gas chromatography (GC/ flame ionization detector and GC/mass spectrometry). Forty components were identified in the oil, representing 98.2-98.6% of the total composition. The oil composition was dominated by oxygenated monoterpenes (73.5-75.0%), with trans-pinocarveol (35.6-36.3%) and pinocarvone (19.8-20.0%) as the most representative. Other components occurring in significant amounts were β-selinene (8.5%) and perillyl acetate (6.0-12.7%). No significant differences were detected in the major volatiles between the two different biological forms (flowering period and dry season) in which the plant naturally occurs.

Vepris macrophylla is an evergreen tree occurring in sub-humid forest of Madagascar and traditionally used in the Island to treat several complaints as well as to prepare aromatic teas and alcoholic drinks. In the present work, the essential oil distilled from the leaves was analyzed for the first time by gas chromatography (GC-FID) and gas chromatography/mass spectrometry (GC/MS). The major compounds were citral (56.3%), i.e., mixture of neral (23.1%) and geranial (33.2%), citronellol (14.5%), and myrcene (8.3%). The essential oil exhibited antimicrobial activity against S. aureus, P. aeruginosa, and C. albicans as determined by vapor-diffusion assay, supporting the traditional use of the plant for preparing steam bath for the treatment of infectious diseases. The essential oil was evaluated for cytotoxic activity on human tumor cell lines by MTT (=3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) assay, showing inhibitory effects comparable to those of cisplatin, notably on MDA-MB 231 (human breast adenocarcinoma) and HCT116 (human colon carcinoma) cell lines. Finally, the essential oil was also subjected to screening for its antioxidant activity and the free radical scavenging capacity.

Gas chromatography/mass spectroscopy analysis (GC/MS) of essential oils obtained from populations of the resurrection plant Myrothamnus moschatus, growing in different areas of Madagascar, allowed identification of three main chemotypes in the species. The first one was provided by plants with a high content of trans-pinocarveol and pinocarvone; the second one involved plants with high percentages of limonene, cis- and trans-p-mentha-1(7),8-dien-2-ol, and β-selinene; and the third chemotype was characterized by plants with high levels of oxygenated sesquiterpenes such as caryophyllene oxide and α- and β-isomers of caryophylla-4(12),8(13)-dien-5-ol. Chemical data were supported by chemometric technique as the principal component analysis. Furthermore, the relationship between the dioecy and phytochemistry within one population was also considered. Finally, correlations between chemical variations and ethnobotanical data were assessed.
