“…On the southern and western edge of its range, this group overlaps a yellow-green race which is found near the Rio Grande River in Texas and in Coahuila and Chihuahua, Mex-only twice prior to this report, and then only as the glycoside. An "uncharacterized glycoside" was found in pollen in Camellia sinensis (Sakamoto, 1969) and the 3-0-rhamnoside in leaves of Atraphaxis pyrifolia (reported as Artaphaxis) (Polygonaceae) (Chumbalov, Mukhamad'yarova and Omurkamzinova, 1974). The aglycone is identical to the aglycone derived by hydrolysis of 8-acetyl and 8-butyryl-7-O-methylherbacetin which was previously isolated from the farinose exudate of Notholaena affinis (Wollenweber et al, 1978).7,4'-Di-O-methylherbacetin has not been previously found in nature, but is identical to the hydrolysis products of 8-butryl-7,4'-di-0methylherbacetin which was also isolated from N. affinis.…”

In Notholaena standleyi (Pteridaceae), differences in geographic range, aspect, height, edaphic requirements, and the color and chemistry of the ceraceous exudate on the abaxial side of the frond suggest at least three distinct subgroups ofthis taxon. One race, with a light yellow exudate consisting mostly ofkaempferol, 3-0-methylkaempferol and 4'-0-methylkaempferol occurs in the eastern portion of the range. A yellow-green race and a gold race possess mostly 7-0methylkaempferol and 4' -O-methylkaempferol but also the uncommon compounds 7-O-methylherbacetin and 7,4'-di-0-methylherbacetin. Plants of the yellow-green race produce minor constituents with methyl substituents in the 3-position whereas those ofthe gold race lack them. Plants of this last group produce only traces of kaempferol.Principal Components Analysis based on nine flavonoid constituents and 59 samples was carried out. Plants ofthe three groups clustered in plots of Principal Components I vs. 2, I vs. 3, and 2 vs. 3 and were separated from each other.These plants reproduce ameiotically and thus there is little or no gene fk, among them and they are geographically distinct. We prefer to maintain them as informally recognized taxa pending further studies.

Antioxidant Flavonols and Phenolic Compounds from Atraphaxis frutescens and Their Inhibitory Activities against Insect Phenoloxidase and Mushroom Tyrosinase

et al. 2016

Chemical investigation of the aerial parts of Atraphaxis frutescens resulted in the isolation of five 7-methoxyflavonols with pyrogallol B-ring moieties (1-5), a fisetinidol glucoside (13), and a benzyl glycoside (18), together with 26 known compounds including flavonoids, phenylpropanoid amides, anthraquinone glycosides, lignans, and a benzyl derivative. The principal chemical structural feature of the isolated compounds was either a pyrogallol or catechol B-ring moiety, and they showed potent 1,1-diphenyl-2-picrylhydrazyl radical scavenging activities. To assess the effects of these antioxidants on biological enzymes, their inhibitory effects against an insect phenoloxidase and a mushroom tyrosinase were evaluated. This study indicated that insect phenoloxidase was inhibited by phenylpropanoid amides and that mushroom tyrosinase was inhibited by the characteristic 7-methoxyflavonol 3-O-rhamnopyranosides.

“…These compounds exhibit anti-inflammatory and antioxidant attributes, which can be invaluable for addressing inflammatory disorders and promoting overall health and wellness. The anti-inflammatory properties make them particularly attractive for conditions involving excessive inflammation, such as arthritis [ 105 , 106 ]. In addition to polyphenols and triterpenoids, Atraphaxis species may also contain alkaloids with diverse pharmacological actions.…”

Atraphaxis is a genus of flowering plants in the family Polygonaceae, with approximately 60 species. Species of Atraphaxis are much-branched woody plants, forming shrubs or shrubby tufts, primarily inhabiting arid zones across the temperate steppe and desert regions of Central Asia, America, and Australia. Atraphaxis species have been used by diverse groups of people all over the world for the treatment of various diseases. However, their biologically active compounds with therapeutic properties have not been investigated well. Studying the biologically active components of Atraphaxis laetevirens, Atraphaxis frutescens, Atraphaxis spinosa L., and Atraphaxis pyrifolia is crucial for several reasons. Firstly, it can unveil the therapeutic potential of these plants, aiding in the development of novel medicines or natural remedies for various health conditions. Understanding their bioactive compounds enables scientists to explore their pharmacological properties, potentially leading to the discovery of new drugs or treatments. Additionally, investigating these components contributes to preserving traditional knowledge and validating the historical uses of these plants in ethnomedicine, thus supporting their conservation and sustainable utilization. These herbs have been used as an anti-inflammatory and hypertension remedies since the dawn of time. Moreover, they have been used to treat a variety of gastrointestinal disorders and problems related to skin in traditional Kazakh medicine. Hence, the genus Atraphaxis can be considered as a potential medicinal plant source that is very rich in biologically active compounds that may exhibit great pharmacological properties, such as antioxidant, antibacterial, antiulcer, hypoglycemic, wound healing, neuroprotective, antidiabetic, and so on. This study aims to provide a collection of publications on the species of Atraphaxis, along with a critical review of the literature data. This review will constitute support for further investigations on the pharmacological activity of these medicinal plant species.
