Their fragmentation patterns were consistent with those of heteroside
derivatives of kaempferol, whose main fragment consists of m/z 285 [[[C.
The genus Escallonia itself contains asperuloside, a heteroside
of limited distribution but commonly occurring in the Rubiaceae (Takhtajan, 1983).
2012) showed that the presence of abundant heteroside
flavonoids and phenolic compounds in the Copaifera langsdorffli extract (Brancalion et al.
Inheritance of caffeine and heteroside
contents in an interspecific cross between a cultivated coffee species Coffea liberica and a wild species caffeine free C.
Our studies show that heteroside
2 is more active than its aglyeon 3 with respective percentages of inhibition of 78.

They provide the majority of alkaloids, heterosides
and essential oils content.
Besides the alkaloids, the triterpenic heterosides
(derived from the quinovic acid) and polyphenols (especially tannin) are also highlighted (PAVEI et al.
Phytochemical tests were conducted to investigate the presence of alkaloids, saponins, tannins, quinones, flavonoids, triterpenes, steroids, heterosides
These compounds, such as alkaloids, flavonoids, tannins, quinones, essential oils, saponins, and cardioactive heterosides
are produced by the plants for their survival (Cardoso et al.
Some of the chemical compounds isolated from the leaves include flavonoids, heterosides
, sulphated derivates, diterpenes, gallic acid, pyrogallol and essential oils (Schneider et al.
Most of the studies in which ginkgo was effective used 120 mg per day of an extract standardized to contain 24% ginkgo heterosides
or 24% ginkgoflavone glycosides and 6% terpenes.
