Ampelozizyphus amazonicus Ducke (Rhamnaceae) is an Amazonian medicinal plant
popularly known as “saracuramirá” or “cervejade-índio” that is found in the Amazon
forest territories, occurring in Brazil in the States of Amazonas, Pará, and Roraima [1].
An aqueous drink with reported tonic and antimalarial properties can be prepared from
the bark and roots of the plant [1]. Ethnopharmacological studies indicate both
stimulatory and energetic properties for
A. amazonicus . Due to the growing interest in
dietary supplements with adaptogen properties, our research group engaged in the study
of its immunomodulatory properties, its chemistry and its biotechnological applications.
The water extract from the barks was spray dried without drying adjuvants, resulting in
a powder (SARF), which was characterized by its physicochemical properties and
proximate, mineral and saponin contents [2,3]. The effect of SARF on the immune
response was investigated which confirmed that SARF possesses immunomodulatory
properties, inducing an in vivo modification of the B lymphocyte response and an
increase in the basal levels of anti-ovalbumin, anti-LPS and anti-dextran IgM antibodies
[2,3]. The SARF saponins were isolated into different groups by countercurrent
chromatography (CCC) and characterized by off-line ultra-high-performance liquid
chromatography/high resolution accurate mass spectrometry (HPLC-HRMS
n
) analysis
[4]. More recently, we initiated the study of a water extract from the woods, which are
discarded in the traditional process of beverage preparation, but generate saponin-rich
extracts as well. A methodology developed to dereplicate aqueous extracts from both
bark and wood by high resolution (HRMS) precursor and tandem mass spectrometry
(MS/MS) will be discussed. Taken together, these results suggest that SARF could be
an interesting new functional ingredient for food applications or pharmaceutical
products.
