Abstract
Objective: Herbal medicine usage is increasing nowadays because their usage is acceptable by most
people to be safe and produce fewer side effects than synthetic drugs. This present study has been
undertaken with the aim to formulate and evaluate herbal gel containing Brassica oleracea ver. italica
methanolic extract. Method: The gel formulation was designed by using methanolic extract of Brassica
oleracea var. italica, Carbopol 940, propylene glycol, methyl paraben, propyl paraben and required
amount of distilled water. PH of skin was maintained by adding tri-ethanolamine drop wise. The
prepared herbal gel formulation was subjected to preliminary evaluation such as pH, total phenolic
content and total flavonoid content, viscosity, drug diffusion study and anti-inflammatory study. Result:
The result of anti-inflammatory study showed that the gels with extract concentration of 1000 µg/ml
have comparable anti-inflammatory activity with the Diclofenac sodium (100 µg/ml).Conclusion:
Formulation of gel containing B. oleracea var. italica extract is a good attempt as herbal formulation has
high demand in the market.
Keywords: Brassica oleracea var. italica, Carbopol 940, Hydrogel.
Introduction
Natural substances have gained major
interest in design and development of drug
delivery system. The use of metals, fungi,
alginates, polysaccharides as formulation or
formulation additives have invited a lot of
research in health industry [1-9]. The advent of
micro and nanotechnology has added an
increased potency in application of natural
substances for treatment of diseases or as
pharmaceutical additives [10, 11]. Family
Brassicaceae consists of 350 genera and 3500
species. One of the most important genus in this
family is Brassica which include crops and
economically important species such as
Brassica oleracea L., Brassica napus L and
Brassica rapa L. Brassica oleracea which
include vegetables and forage forms is the main
vegetables species. It includes vegetables such
as kale, cabbage, broccoli, Brussel sprouts,
cauliflower and others [12].
Broccoli is an edible green plant in the
cabbage family whose large flowering head is
eaten as a vegetable. The word broccoli comes
from the Italian plural of broccoli, which means
“the flowering crest of a cabbage” and is the
diminutive form of broco, meaning “small nail”
or “sprout” [13]. The sprouts refer to the
branching habit of broccoli and young edible
inflorescences. They are introduced from
eastern Mediterranean to the Italy where
diversity of broccoli-like vegetables was
developed [14]. Broccoli provides many health-
promoting properties which attributes to its
antioxidant and anti-carcinogenic compounds. It
is composed of polyphenols, glucosinolates,
sulforaphane and selenium [15]. They are also
known to contain a high content of flavonoids,
vitamins, and mineral nutrients [16-18]. The
pharmacokinetics of broccoli explains that
when hydrolysis takes place, glucoraphanin
produces many products that include the
bioactive isothiocyanate sulforaphane. The
percentage of isothiocyanate sulforaphane
present in these vegetables varies depending
upon the conditions of hydrolysis, food
