Abstract
Two intergeneric hybrids between Ligularia nelumbifolia and Cremanthodium stenoglossum were examined with respect to the chemical composition of root extracts and the sequences of neutral DNA regions. The DNA data showed that the direction of hybridization was different between the individuals. Eremophilane sesquiterpenes were found in both hybrids and deduced to have come from their Cremanthodium parents, because sesquiterpenes were detected in C. stenoglossum but not in L. nelumbifolia.

Abstract
Chemical constituents of Cremanthodium angustifolium, C. brunneopilosum, C. campanulatum, C. daochengense, C. discoideum, C. ellisii, C. helianthus, C. lineare, C. nobile, C. potaninii, C. principis, C. pulchrum, C. rhodocephalum, C. stenactinium, C. pleurocaule, and C. stenoglossum were reviewed. They produced mainly sesquiterpenoids–bicyclic and/or tricyclic eremophilanes, bisabolanes, bakkanes–and related compounds. Cremanthodium was shown to be close to Ligularia in chemical constituents.

Abstract
The chemical constituents in the roots of 3 Cremanthodium campanulatum Diels (Asteraceae) samples collected in Yunnan and Sichuan Provinces, China, were chemically investigated. A total of 8 bisabolane-type sesquiterpenoids, 2 of which were new, and a new oplopane-type sesquiterpenoid, along with a new lignan were isolated and their structures elucidated based on spectroscopic analyses. This is the first report on the chemical study of C. campanulatum.

Abstract
The genus Phlomis is represented in the island of Crete (Greece, Eastern Mediterranean) by three species Phlomis cretica C. Presl., Phlomis fruticosa L., the island endemic Phlomis lanata Willd. and three hybrids Phlomis x cytherea Rech.f. (P. cretica x P. fruticosa), Phlomis x commixta Rech.f. (P. cretica x P. lanata) and Phlomis x sieberi Vierh. (P. fruticosa x P. lanata). This work describes (a) the profile of hybrids and parental species concerning their volatile compounds, (b) the suitability of ribosomal nuclear (ITS region), chloroplast (trnH-psbA), and AFLP markers to identify hybrids and (c) their competence to characterize the different chemotypes of both hybrids and their parental species. The cluster analysis and PCA constructed from chemical data (volatile oils) suggest that there are three groups of taxa. Group IA includes P. cretica and P. fruticosa, group IB includes P. x cytherea, whereas group II consists of P. x commixta, P. x sieberi and P. lanata. Volatile compounds detected only in the hybrids P. x sieberi and P. x commixta correspond to the 3% of the total compounds, value that is much higher in P. x cytherea (21%). Neighbor-joining, statistical parsimony analysis and the observations drawn from ribotypes spectrum of ITS markers divided Phlomis species in two groups, P. lanata and the complex P. cretica/P. fruticosa. In contrast to the ITS region, the plastid DNA marker follows a geographically related pattern. Neighbor-Net, PCA and Bayesian assignment analysis performed for AFLP markers separated the genotypes into three groups corresponding to populations of P. cretica, P. fruticosa, and P. lanata, respectively, while populations of P. x commixta, P. x cytherea, and P. x sieberi presented admixed ancestry. Most of the P. x cytherea samples were identified as F1 hybrids by Bayesian assignment test, while those of P. x commixta and P. x sieberi were identified as F2 hybrids. Overall, high chemical differentiation is revealed in one of the three hybrids, which is likely related with niche variation. Moreover, molecular markers show potential to identify Phlomis taxa.

Abstract
Different geographical plant populations within a single species can exhibit variation, in the production of secondary metabolites. Genetic and environmental variations both contribute to differences between populations; however, the relative importance of these factors is unclear. Here, the extent of variation in the production of four flavonoid glycosides (epimedin A, B, C and icariin) were investigated in eleven wild populations of Epimedium sagittatum used in traditional Chinese medicine. Secondary metabolite profiles were classified into five chemotypes. A common garden experiment indicated this chemotype variation has a significant genetic basis. Extensive genetic variation among intraspecific populations was shown using a retrotransposon-based molecular marker system. These results will assist in development of strategies for conservation, utilization and domestication of E. sagittatum.
