“…The compound exhibited larvicidal activity against the fourth-instar larvae of Aedes aegypti , Anopheles sinensis , and Culex pipiens pallens , and it also possessed nematocidal activity against Bursaphelenchus xylophilus and Meloidogynein congnita . Choe et al [ 9 ] reported that the leaf extract of O. japonica showed significant antimicrobial activity against Bacillus cereus , Pseudomonas aeruginosa , Staphylococcus aureus , and Streptococcus mutans . Huang et al [ 10 ] isolated eighteen quinoline alkaloids from the roots of O. japonica , and some of the compounds showed significant anti-pathogenic fungal activity, with one compound demonstrating superior efficacy to that of the positive control hymexazol.…”

“…A. orixae is the first endophytic fungus of Amphisphaeria that forms a hyphomycetous asexual morph and is unique in undergoing thallic or blastic conidiogenesis and having polymorphic conidia. Thirteen secondary metabolites were identified from the rice fermentation product of A. orixae, including a new isocoumarin, (R)-4,6,8-trihydroxy-5-methylisochroman-1-one (1), and 12 known compounds (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). Their chemical structures are depicted in Figure 4 and were established using 1D-and 2D-NMR, mass spectrometry, and chemical computations.…”

Endophytic fungi are a remarkably diverse group of microorganisms that have imperceptible associations with their hosts for at least a part of their life cycle. The enormous biological diversity and the capability of producing bioactive secondary metabolites such as alkaloids, terpenoids, and polyketides have attracted the attention of different scientific communities, resulting in numerous investigations on these fungal endophytes. During our surveys of plant-root-based fungi in the mountain areas of Qingzhen, Guizhou Province, several isolates of endophytic fungi were identified. In this study, a novel endophytic fungus was discovered in the roots of a medicinal plant (Orixa japonica) in Southern China and introduced as a new species (Amphisphaeria orixae) based on morphological evidence and molecular phylogenetic analysis (combined ITS and LSU sequence data). To the best of our knowledge, A. orixae is the first reported endophyte as well as the first hyphomycetous asexual morph in Amphisphaeria. A new isocoumarin, (R)-4,6,8-trihydroxy-5-methylisochroman-1-one (1), and 12 known compounds (2–13) were isolated from the rice fermentation products of this fungus. Using 1D- and 2D-NMR, mass spectrometry, and ECD studies, their structures were identified. The antitumor activity of these compounds was tested. Unfortunately, none of the compounds tested showed significant antitumor activity.

Asparagus Cochinchinensis is known to ameliorate respiratory disease. We evaluated the antimicrobial activity of non-fermented and fermented A. cochinchinensis using lactic acid bacteria and investigated the physicochemical characteristics of the fermented A.cochinchinensis. Non-fermented A.cochinchinensis showed lower levels of antimicrobial activity than the fermented A.cochinchinensis. Ethyl acetate (EtOAc) extracts of the fermented A. cochinchinensis showed antimicrobial activities against the indicator strains at lower minimum inhibitory concentration (MIC). The MIC of the EtOAc extract of non-fermented A. cochinchinensis against Escherichia coli, Staphylococcus epidermidis, and Stphylococcus aureus were 100, 75, and 100 mg/ml. In contrast, the MIC of the EtOAc extract of ACLM was 25 mg/mL against E. coli. The MIC of the EtOAc extract of ACLS was 12.5 mg/mL against S.epidermidis, and the MIC of the EtOAc extract ofACLP was 12.5 mg/mL against S.aureus. The viable cell number, pH, and acidity of A. cochinchinensis fermented by Lactobacillussakei 383 were similar to those of A. cochinchinensis fermented by Leuconostocmesenteroides 4395, but were different from those of A. cochinchinensis fermented by Lactobacillus.plantarum KCCM 11322. These results suggested that the fermented A. cochinchinensis by lactic acid bacteria may be a good candidate for application to ameliorate respiratory disease.

This study was carried out to investigate antimicrobial activity and characteristics of Asparagus cochinchinenesis which was steamed and fermented with lactic acid bacteria. A. cochinchinensis was prepared to steaming process which was washed and freeze dried. A. cochinchinensis was steamed at 95°C for 12 h and dried by hot air at 50°C for 24 h. After steaming process, A. cochinchinensis was fermented with lactic acid bacteria (Leuconostoc mesenteroides 4395, Lactobacillus sakei 383 and Lactobacillus plantarum KCCM 11322). Ethyl acetate extracts of fermented A. cochinchinensis had antimicrobial activities for the respiratory disease bacteria (Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa and Escherichia coli). A. cochinchinensis had highest antimicrobial activity for the P. aeruginosa which fermented with L. mesenteroides 4395. The minimum inhibition concentration (MIC) of A. cochinchinensis fermented with L. mesenteroides 4395 was 10 mg/mL for S. aureus, S. epidermidis, E. coli and 5 mg/mL for P. aeruginosa. The MIC of A. cochinchinensis fermented with L. sakei 383 and A. cochinchinensis fermented with L. plantarum KCCM 11322 were the same. Total sugar was decreased from 863.33±17.47 mg/mL to 722.67±5.51 mg/mL during the steaming process. But reducing sugar was increased from 99.36±1.32 mg/mL to 109.29±2.71 mg/mL during the steaming process. Total sugar was decreased to 301.50-361.42 mg/mL and reducing sugar was decreased to 27.39-62.20 mg/mL during the fermentation process.
