A biflavanone from Cycas beddomei

Phytochemistry, 2000
A new biflavanone, 7,7"-di-O-methyltetrahydrohinokiflavone together with tetrahydrohinokiflavone were isolated from the stems of Cycas beddomei. The structures were established on the basis of spectral and chemical studies.

Cycasin Content of Cycas circinalis

Nature, 1965
RECENTLY, scientific interest in the toxicity of cycads has been stimulated by recognition of the high incidence of amyotrophic lateral sclerosis in Guam and the Mariana islands1. In the course of the search for possible aetiological agents and toxic substances responsible for amyotrophic lateral sclerosis, it was found that nuts of Cycas circinalis ...

Eco-evolutionary evidence for the global diversity pattern of Cycas (Cycadaceae).

Journal of Integrative Plant Biology
The evolution of the latitudinal diversity gradient (LDG), characterized by a peak in diversity toward the tropics, has captured significant attention in evolutionary biology and ecology.

Polyphasic approach identifies two new species of Desmonostoc (Nostocales, Cyanobacteria) in the coralloid roots of Cycas fairylakea (Cycadales)

Phycologia, 2021
Endogenously formed coralloid roots in living cycads are known to be infected and maintained by a mutual partnership with photosynthetic cyanobacteria. In this study, two strains of filamentous, nitrogen-fixing endosymbiotic cyanobacteria from the green ...

Lectotypification of Cycas beddomei (Cycadaceae)

Phytotaxa, 2018
During the revision of Indian cycads, we attempted to consult type specimens of the endangered species, Cycas beddomei(1883: 85) and in the process realized there has been a great deal of confusion in previous literature regarding the syntypes of this species.

Nonprotein amino acids from Cycas revoluta

Phytochemistry, 1997
Two nonprotein amino acids, cycasindene and cycasthioamide, along with eight known nonprotein amino acids, were isolated from the seeds of Cycas revoluta Thunb. The structures of cycasindene and cycasthioamide were elucidated as 3-[3'-amino-indenyl-2]-alanine (1) and N-[glycinyl-alaninyl-11-thio]-5-one-pipecolic acid (2) by chemical and spectral ...

Species delimitation with distinct methods based on molecular data to elucidate species boundaries in the Cycas taiwaniana complex (Cycadaceae)

Taxon, 2021
Accurately delimiting species boundaries is of critical importance in many areas of biology including population genetics, conservation biology, biogeography, and evolutionary biology because inaccurate species delimitation may significantly affect ...
