Moringa oleifera Lam commonly known as “drumstick”,
belongs to Moringaceae family. The derivatives of caffeic, pcoumaric
and ferulic acids are dominant phenolic
constituents which are present in Moringa oleifera leaves
extract. [12]
The different plant extracts will have different modes of
action for curing diseases and in mixture form may exhibit
enhanced activity than that of individual plants, which is
known as ‘synergistic action’. A particular principle in the
pure form may have only a fraction of the pharmacological
activity than it has in its plant matrix. This highlights the
importance of using the plant as a whole or a mixture of
plants for treating a disease. [13] The objectives of the present
study were to quantify total phenolics, flavonoids and
flavonols in the combination of the four medicinal plant
extracts selected; that included leaves of Aloe vera, Bacopa
monniera, Moringa oleifera and rhizome of Zingiber
officinale. It was also aimed to observe the antioxidant
properties in terms of DPPH scavenging activity and
reducing power of the individual plant extracts and their
combinations for existences of any synergistic property of the
four medicinal plant extracts selected.
