Volatile compounds of five mangrove species and parts

Mangrove plants contain a variety of secondary metabolites, which are important for their survival and adaptation to the coastal environment, as well as for producing bioactive compounds. To reveal differences in mangrove volatiles, a GC-MS method was built up and used to analyze and identify five mangrove species' leaf, root, and stem. The relative content and type of volatile compounds were counted and compared, and their pathway enrichment analysis was performed. The results showed that 532 compounds were detected in the leaf, root, and stem parts of five mangrove species, which were grouped into 18 classes including alcohols, aldehydes, alkaloids, alkanes, etc. The number of compounds found was from 41 to 86 in each part of five mangrove species, A. corniculatum leaves and A. marina roots contained a maximum of 86 compounds. 247 compounds were found in A. corniculatum, 245 in K. candel, and 240 in A. marina. Roots, stems, and leaves each had 399, 342, and 339 compounds. There were 4..., Plant Material
The seedlings of five mangroves, A. ilicifolius, B. gymnorrhiza, A. corniculatum, K. candel, and A. marina were collected from Tongming river, which is located in Zhanjiang Mangrove National Nature Reserve, Guangdong (E110.1667°, N 20.9765°). The seedlings were 1.5 years old and 25–50 cm high. The morphological characteristics of the seedlings of the five mangrove species used in this study species were shown in Figure 1. Three plants were taken from each mangrove species' leaves, roots, and stems for biological duplication, and the combinations of species and organ parts from the leaves, roots, and stems were coded and named species_part. Leaves, roots, and stems of A. ilicifolius (AI), B. gymnorrhiza (BG), A. corniculatum (AC), K. candel (KC), and A. marina (AM) were simplified as AI_leaf, AI_root, AI_stem, BG_leaf, BG_root, BG_stem, AC_leaf, AC_root, AC_stem; KC_leaf, KC_root, KC_stem, AM_leaf, AM_root, AM_stem, respectively.
