Osmunda japonica Extract Suppresses Pro-Inflammatory Cytokines by Downregulating NF-kappaB Activation in Periodontal Ligament Fibroblasts Infected with Oral Pathogenic Bacteria.
Seong J, Lee J, Lim YK, Yoon WJ, Jung S, Kook JK, Lee TH. Seong J, et al. Int J Mol Sci. 2020 Apr 1;21(7):2453. doi: 10.3390/ijms21072453. Int J Mol Sci. 2020. PMID: 32244806 Free PMC article.
P. gingivalis is an obligate anaerobic species that induces gingival inflammation by secreting virulence factors. In this study, we investigated whether Osmunda japonica extract exerted anti-inflammatory effects in primary PDLFs stimulated by oral pathogens. ...

Rheophytic Osmunda lancea (Osmundaceae) exhibits large flexibility in the petiole.
Shiba M, Fukuda T. Shiba M, et al. Sci Rep. 2024 Feb 4;14(1):2866. doi: 10.1038/s41598-024-53406-4. Sci Rep. 2024. PMID: 38311628 Free PMC article.
Our morphological, anatomical, and mechanical analyses on the petioles of Osmunda lancea (Osmundaceae) along the river and an inland sister species of O. japonica revealed that the petioles of O. lancea had a larger cell volume in subepidermal cortex and were more flexible …

Osmunda pulchella sp. nov. from the Jurassic of Sweden--reconciling molecular and fossil evidence in the phylogeny of modern royal ferns (Osmundaceae).
Bomfleur B, Grimm GW, McLoughlin S. Bomfleur B, et al. BMC Evol Biol. 2015 Jun 30;15:126. doi: 10.1186/s12862-015-0400-7. BMC Evol Biol. 2015. PMID: 26123220 Free PMC article.
BACKGROUND: The classification of royal ferns (Osmundaceae) has long remained controversial. Recent molecular phylogenies indicate that Osmunda is paraphyletic and needs to be separated into Osmundastrum and Osmunda s.str. ...CONCLUSIONS: Osmunda pulchella is …

Fern gametophytes of Angiopteris lygodiifolia and Osmunda japonica harbor diverse Mucoromycotina fungi.
Ogura-Tsujita Y, Yamamoto K, Hirayama Y, Ebihara A, Morita N, Imaichi R. Ogura-Tsujita Y, et al. J Plant Res. 2019 Sep;132(5):581-588. doi: 10.1007/s10265-019-01121-x. Epub 2019 Jul 10. J Plant Res. 2019. PMID: 31292767
To explore whether Mucoromycotina colonize fern gametophytes, we subjected fungal associations with gametophytes of two distantly related ferns, Angiopteris lygodiifolia (Marattiales) and Osmunda japonica (Osmundales), to molecular analysis. Direct PCR amplification from i …

Chemical constituents, cytotoxic and antioxidant activities of extract from the rhizomes of Osmunda japonica Thunb.
Bowen L, Li C, Bin L, Ying T, Shijun L, Junxing D. Bowen L, et al. Nat Prod Res. 2020 Mar;34(6):847-850. doi: 10.1080/14786419.2018.1501692. Epub 2018 Nov 16. Nat Prod Res. 2020. PMID: 30445844
Thirty-three compounds (1-33) were isolated from the rhizomes of Osmunda japonica. Their structures were elucidated on the basis of spectral analysis and identified as ent-kaurene terpenoids (1-3), anthraquinones (4-8), flavonoids (9-12), steroids (13-15), and other compou …
