The volatile oils from Marchantia convoluta were obtained by microwave extraction (ME) and phytosol extraction (PE) methods. The attained extracts were analyzed by gas chromatography with mass spectrometric detector (GC-MS). The compounds were identified according to their retention indices and mass spectra (EI, 70 eV). A total of fourteen compounds were identified in ME extract accounting for 80.72% of total peak area. Isolongifolene (24.588%), 1, 2-benzenedicarboxylic acid, butyl cyclohexyl ester (10.768%), pyrene (9.328%) and hexadecanoic acid, ethyl ester (8.570%) were the major compounds identified from ME extract. The analytical results of ME extract were compared with PE method. The ME extract was found to be markedly different from that of PE extract. A total of seven compounds in PE extract were identified accounting for 74.275% total peak area. 1-Phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10, 10a-octahydro-1, 4a-dimethyl-7-(1-methylethyl) methyl ester were the major compounds.

“…About 65% of the studied species have sporophytic self-incompatibility, a prezygotic system that ensures high genetic variability in the offspring (Ferrer & Good-Avila 2007;Jeffrey 2009). At the same time, there are partially self-compatible or self-compatible species (Torres Díaz et al 2007;Torres & Galetto 2008;Ferrer et al 2009). Few data are available on the reproductive system of the genus: Flourensia campestris was reported as self-incompatible (Torres & Galetto 2008) and F. cernua as partially self-incompatible (Ferrer et al 2009).…”

Reproductive biology, seed germination and regeneration ofFlourensiaDC. species endemic to Central Argentina (Asteraceae)

Our objective was to study reproductive biology, seed germination and regeneration, through morphoanatomical and field observations and controlled experiments, to assess reproductive strategies in six rare Flourensia endemic to Central Argentina (F. campestris, F. hirta, F. leptopoda, F. niederleinii, F. oolepis, F. tortuosa). Structure of capitula, flowers, and achenes was described. Capitula were visited by a variety of insects. Achenes required 30-45 days to mature. Fruit set varied significantly among species. Flourensia campestris and F. oolepis were self-incompatible. Seed viability decreased after 19 months and was lost after 32 months. Flourensia oolepis and F. campestris had the highest germination percentages (>60%); the addition of gibberellic acid in 2-months old seeds did not influence germination. The remaining species had lower germination percentages (<30%). All species had xylopodia that were root and stem modifications. Burned individuals of F. campestris actively regenerated from underground buds of xylopodia, being suitable for restoration of degraded or burned areas. Flourensia campestris and F. oolepis had better reproductive success, but the remainder species can be considered at risk. Strategies should be implemented to protect them, such as to preserve its habitat together with attempts to increase their population sizes and maintain their pollinators.

“…Preliminary identifications were confirmed by the observation of peak enhancements upon co-injection of standards: linalool, 1,8-cineol, α-cubebene, α-humulene, and alloaromadendrene, obtained from Aldrich-Sigma USA, and β-elemene, βcaryophyllene, α-himachalene, and ∆ 1(10) -aristolene, all previously identified compounds in roots of A. chilensis 8 . When standards were not available, mass spectra were compared with published spectrometric data 8,[15][16][17] . Also, Kovats index of the peaks were compared with values from the literature [15][16][17] .…”

In this communication we report the essential oil composition of Aristolochia chilensis Bridges ex Lindl. fresh leaves. This species is one of the larval food-plants of Battus polydamas Boisd., the only butterfly of the family Papilionidae (Lepidoptera) occurring in Chile. In order to determine possible chemical similarities among several of its host species distributed throughout the continent, we compared these results with data obtained from literature on the composition of other representative Aristolochia species occurring in Argentina, Paraguay, and Brazil. Instead of the expected, it was found that the essential oil of each species considered in this work exhibits a particular characteristic profile.
