“…Its tender leaves are used as edible vegetables in the south of China, and the matured leaves are used for the treatment of the above diseases 4 . It has been reported that the leaves of P. serratifolia contain essential oils, triterpenoids, flavonoids, polyphenols, and other bioactive compounds, which have been demonstrated to have antioxidant and anticancer activities in vitro 4,5 .The boundaries of some species have not been clearly defined in Rosaceae family due to similar morphological features exhibiting among Rosaceae species 1 . Compared with morphological identification, DNA sequences can produce more accurate phylogenetic relationships 1,6 .…”

Plant mitochondrial genomes (mitogenomes) are a valuable source of genetic information for a better understanding of phylogenetic relationships. However, no mitogenome of any species in the genus of Photinia has been reported. In this study, using NGS sequencing, we reported the mitogenome assembly and annotation of Photinia serratifolia, which is 473,579 bp in length, contains 38 protein-coding genes, 23 tRNAs, and 6 rRNAs, with 61 genes have no introns. The rps2 and rps11 genes are missing in the P. serratifolia mitogenome. Although there are more editing sites (488) in the P. serratifolia mitogenome than in most angiosperms, fewer editing types were found in the P. serratifolia mitogenome, showing a clear bias in RNA-editing. Phylogenetic analysis based on the mitogenomes of P. serratifolia and 8 other taxa of the Rosaceae family reflected the exact evolutionary and taxonomic status of P. serratifolia. However, Ka/Ks analysis revealed that 72.69% of the protein-coding genes in the P. serratifolia mitogenome had undergone negative selections, reflecting the importance of those genes in the P. serratifolia mitogenome. Collectively, these results will provide valuable information for the evolution of P. serratifolia and provide insight into the evolutionary relationships within Photinia and the Rosaceae family.

“…Phytochemical research showed that triterpenoids and cyanophoric glycosides, for example, ursane triterpenoids and analogs, ursolic acid, oleanolic acid, prunasin, and saponin, were the main compounds in the leaves of P. serrulata [2][3][4][5][6][7]. Pharmacological investigations showed that the leaves of P. serrulata are toxic, possess antioxidant and antibacterial activity, can kill Tetranychus cinnabarinus and can suppress plant growth [6][7][8][9][10][11]. No research has so far been conducted concerning the chemical constituents of the essential oil of the flowers.…”

547.913Photinia serrulata Lindl. belongs to the Rosaceae family and is distributed in Shanxi, Gansu, Anhui, Jiangsu, Henan, and Hunan Provinces in China [1]. Phytochemical research showed that triterpenoids and cyanophoric glycosides, for example, ursane triterpenoids and analogs, ursolic acid, oleanolic acid, prunasin, and saponin, were the main compounds in the leaves of P. serrulata [2][3][4][5][6][7]. Pharmacological investigations showed that the leaves of P. serrulata are toxic, possess antioxidant and antibacterial activity, can kill Tetranychus cinnabarinus and can suppress plant growth [6][7][8][9][10][11]. No research has so far been conducted concerning the chemical constituents of the essential oil of the flowers.In order to identify the chemical constituents of the essential oil of P. serrulata flowers, we used the HS-SPME technique with subsequent analysis by GC-MS.The flowers of P. serrulata were collected in Kaifeng, Henan, in July 2010. They were identified by Assoc. Prof. Changqian Li. A voucher specimen was deposited in the Institute of Chinese Materia Medica, Henan University.Volatile organic compounds were extracted in a manual SPME holder together with 5 mL vials and PDMS-DVB fibers (65 Pm) purchased from Supelco Inc. (Bellefonte, USA). The powder of P. serrulata flowers (about 0.7 g) was placed in vials (5 mL). PDMS-DVB fiber of the SPME was aged 10 min in the inlet of the GC, with carrier gas flow 1.0 mL per minute; then the SPME fiber was exposed in the upper space of the sealed vial for 30 min at 80qC to adsorb the analytes. After that, the fiber was withdrawn and directly inserted into the GC-MS inlet for desorption of the volatiles for 1 min.HS-SPME-GC-MS analysis was carried out using an Agilent 6890 N gas chromatograph equipped with an HP-5 MS capillary column (5% phenylmethylsiloxane, 30 m u 0.25 mm, film thickness 0.25 Pm, Agilent Technologies, USA) and coupled with a 5975B mass selective detector spectrometer from the same company. The front inlet was kept at 250qC in the splitless mode. The temperature program was as follows: initial column temperature 50qC, held for 2 min, then programmed to 120qC at a rate of 8qC per minute and held for 2 min and finally programmed to 220qC at a rate of 4qC per minute and held at 220qC for 5 min. Flow rate of split injection was 1.0 mL per minute. As a carrier gas, helium at 1.0 mL per minute was used. The MS detector was used in the EI mode with an ionization voltage of 70 eV. The ion source temperature was at 230qC. The transfer line was at 280qC. The spectra were collected over the mass range (m/z) 30-440. Retention indices were calculated by using the retention times of n-alkanes that were injected at the same chromatographic conditions [12]. Compounds were identified by comparison of their relative retention indices and computer matching with the Wiley 275.L library.The volatiles in the flowers of P. serrulata are presented in Table 1. Thirty-three compounds were identified, which comprised 93.8% of the total volatiles. Volatiles in flower...
