TL;DR: High efficiency of large scale sampling from distribution range of species in identifying novel compounds is suggested and the unique pattern of geographic structuring also provides novel information to unravel cryptic variation in Heracleum.

Abstract: Conspecific populations of plants in their native range are expected to show considerable variation due to long-term ecological and evolutionary factors. We investigated the levels of secondary metabolites in Heracleum including H. persicum a valuable medicinal plant to depict the magnitude of cryptic variation and the potential significance of novel chemical traits. The essential oil volatiles from fruits of 34 populations from different species of Heracleum in Iranian distribution range and a native of H. sphondylium and an invasive population of H. persicum from Norway were analyzed with GC/MS. Out of 48 compounds identified, a contrasting pattern in the level of two major compounds, octyl acetate and hexyl butyrate was found among all studied species. Interestingly, a significant geographic pattern was observed; the hexyl butyrate/octyl acetate ratio was high (range 1.8 - 3.2) in the northwestern Iranian populations of H. persicum compared to that in northern and central populations (range 0.3 - 0.9). Four populations from Zagros mountains also exhibited a unique composition. Anethole was found in two populations of H. persicum from central Zagros, which has not been previously reported for essential oil of fruits of Heracleum so far. The results suggest high efficiency of large scale sampling from distribution range of species in identifying novel compounds. The unique pattern of geographic structuring also provides novel information to unravel cryptic variation in Heracleum.

Chemosystematic Significance of Essential Oil Constituents and Furanocoumarins of Underground Parts and Fruits of Nine Heracleum L. Taxa from Southeastern Europe.
TL;DR: Multivariate statistics (PCA, nMDS, UPGMA), of analyzed metabolites showed that the investigated taxa were grouped according to their taxonomic classification, and the significance of some monoterpenes and (Z)‐falcarinol of the underground parts oils, octyl esters of the fruit oils, and most of the total of 12 identified furanocoumarins.

Disentangling the genetic origin of Heracleum persicum (Apiaceae) in Europe: multiple introductions from multiple source populations
Mohsen Falahati-Anbaran,Mohsen Falahati-Anbaran,Dilli Prasad Rijal,Sverre Lundemo,Inger Greve Alsos,Hans K. Stenøien +5 more
TL;DR: The extent of genetic structuring in the native range is determined, and the origin and the invasion history of Persian hogweed, Heracleum persicum, into Europe is reconstructed, supporting contribution from multiple genetic lineages in recent ancestry of introduced populations and suggesting the potential for ecological diversification within the introduced range.

TL;DR: Both Bayesian and distance-based clustering, and principal coordinate analyses clearly separated these into two groups, and high genetic similarity was found between H. persicum and H. rechingeri populations, questioning taxonomic separation at the species level between these taxa.

Evolution of secondary metabolites from an ecological and molecular phylogenetic perspective.
TL;DR: The distribution of secondary metabolite profiles mean that the systematic value of chemical characters becomes a matter of interpretation in the same way as traditional morphological markers and their occurrence apparently reflects adaptations and particular life strategies embedded in a given phylogenetic framework.

Factors affecting secondary metabolite production in plants: volatile components and essential oils
TL;DR: The presence, yield and composition of secondary metabolites in plants, viz. the volatile components and those occurring in essential oils, can be affected in a number of ways, from their formation in the plant to their final isolation.
