“…However, cryptic species are known to occur in several species complexes of Bostrychia , such as B. tenella , B. radicans , B. moritziana , B. simpliciuscula , B. calliptera and B. intricata [2,3]. Although the genus Bostrychia has recently received attention regarding its phylogeny and evolution, only a few studies have addressed their chemical composition, including reports on the occurrence of fatty acids, amino acids, carbohydrates, polysaccharides, betaines, phenolics, and mycosporine-like amino acids (MAAs) [4,5,6,7,8,9]. Regarding the latter, Bostrychia species have been reported to produce varying quantities of the UV-absorbing compounds mycosporine-glycine, shinorine, porphyra-334, palythine, asterina-330 and palythinol [9,10], however there are no detailed structural reports on the betaines.…”
