Fern constituents: triterpenoids from Adiantum capillus-veneris.
Two new migrated hopane triterpenoids, viz. 4alpha-hydroxyfilican-3-one and fern-9(11)-en-12beta-ol, and olean-18-en-3-one and olean-12-en-3-one as the first example of oleanane compounds from Adiantum ferns were isolated along with many other known triterpenoids from Adiantum capillus-veneris of China and Egypt. Their structures were elucidated by spectroscopic analyses.
متن کاملThe fern Adiantum capillus-veneris lacks stomatal responses to blue light.
We investigated the responses of stomata to light in the fern Adiantum capillus-veneris, a typical species of Leptosporangiopsida. Stomata in the intact leaves of the sporophytes opened in response to red light, but they did not open when blue light was superimposed on the red light. The results were confirmed in the isolated Adiantum epidermis. The red light-induced stomatal response was not a...
متن کاملComplete nucleotide sequence of the chloroplast genome from a leptosporangiate fern, Adiantum capillus-veneris L.
We determined the complete nucleotide sequence of the chloroplast genome of the leptosporangiate fern, Adiantum capillus-veneris L. (Pteridaceae). The circular genome is 150,568 bp, with a large single-copy region (LSC) of 82,282 bp, a small-single copy region (SSC) of 21,392 bp and inverted repeats (IR) of 23,447 bp each. We compared the sequence to other published chloroplast genomes to infer...
متن کاملAdiantum capillus-veneris Linn. (Maidenhair fern) in modern phytotherapy
Background and objectives: Maidenhair fern is an herbal medicine belonging to the family Pteridaceae which is extensively found in Atlantic coast as far as Ireland, America and Iran. The fronds of Adiantum capillus-veneris are prescribed for treatment of different diseases. Different phytochemical compositions such as flavonoids, alkaloids, tannins, terpenoids, etc...
متن کاملCryptochrome nucleocytoplasmic distribution and gene expression are regulated by light quality in the fern Adiantum capillus-veneris.
Numerous cellular responses are reportedly regulated by blue light in gametophytes of lower plants; however, the molecular mechanisms of these responses are not known. Here, we report the isolation of two blue light photoreceptor genes, designated cryptochrome genes 4 and 5 (CRY4 and CRY5), from the fern Adiantum capillus-veneris. Because previously we identified three cryptochrome genes, this ...
