Natural α, β-amyrins were isolated from endemic Brazilian Esenbeckia grandiflora Mart., and
eight synthetic derivatives were obtained by esterification reactions with bromo acetate …

Four derivatives of an α, β-amyrin mixture were synthesized by acylation with appropriate
anhydrides. The structures of the compounds were confirmed by means of IR and 1H and …

Pentacyclic triterpenes are ubiquitously distributed throughout the plant kingdom, in a free
form as aglycones or in combined forms, and have long been known to have a number of …

The isomeric mixture of alpha and beta amyrin (AMY), present in the resin of Protium
heptaphyllum, is popularly used as anti-inflammatory and anti-ulcer. The literature has been …

α-Amyrenone and β-amyrenone are triterpenoid isomers that occur naturally in very low
concentrations in several oleoresins from Brazilian Amazon species of Protium …

Abstract α‐and β‐Amyrins are naturally occurring triterpenes with a wide range of biological
activities. In this study, a reliable GC‐MS method was developed and validated for the …

Three new O-prenylated flavonoids, amyrisins A–C (1–3), were isolated from the leaves and
twigs of Amyris madrensis, along with the known compound polygamain (4). The structures …

α, β Amyrin (ABAM) is a natural mixture of pentacyclic triterpenes that has shown a variety of
pharmacological properties, including anti-inflammatory effect. ABAM is isolated from …

Fifteen different derivatives of an α-and β-amyrin mixture were synthesized by acylation with
appropriate anhydride or acid chlorides and oxidation in the presence of tert-butyl chromate …

The purpose of this research work was to design and synthesize triazolylnapthyl derivative
of β-amyrin (TNB) using click chemistry approach. The cytotoxic activity of TNB was …
