Phenolic and terpenic chemical composition of 7 Timema host plants

We extracted and quantified compounds in the phenolic and terpene classes of secondary metabolites from leaves of seven Timema stick insects host plant species included in a feeding experiments (i.e., Ceanothus thyrsiflorus (lil), Adenostoma fasciculatum (cha), Quercus agrifolia (oak), Arctostaphylos glauca (mz), Pseudotsuga menziesii (df), Abies concolor (wf), Sequoia sempervirens (rdw); see Table 1 of the related article), for terpenes and phenolics, respectively. For each plant species, we extracted compounds from five independent replicates for both phenols and terpenes (See the related article to know more about the used Methods).
