ingredient were developed. Nano-niosomes containing Allium sativa encapsulated with sorbitan
monooleate (0.3%) and PEG400 (1%) has the average particle size of 171 nm and exhibited
excellent stability after heating-cooling 6 cycles, at room temperature, and at 40 °C for 1 month.
Particle size of selected formulation in all tested conditions was changed within the range of ± 7.07
%. Allium sativum extract exhibited the highest lipolysis activity. Therefore, it was selected to be
the active ingredient in nano-niosome for cellulite treatment. Nano-niosomes containing Allium
sativum extract encapsulated with sorbitan monooleate (0.3%) and PEG400 (1%) has the particle
size lower than 200 nm and exhibited excellent stability after heating-cooling 6 cycles and room
temperature of 40 °C for 1 month.
Key words: Cellulite treatment, herbal extracts, lipolysis, nano formulation.

<strong>Abstract</strong>: Like many other plants and herbs, Swertia charata has also been used for treating
different infections and diseases particularly liver disorder. Anti-diseased function of most of the
plants or herbs extracts has been associated with its antioxidant and anti bacterial potential. This
study was performed to explore the antioxidant and antibacterial activity of the Swertia charata
(Bush ham) endemic to the central Punjab of Pakistan. This was done by measuring possible
constituents responsible for its anti-oxidant activity e.g. DPPH radical scavenging potential, total
phenolic contents, reducing power, total flavonoide contents, and antibacterial power against four
different strains of gram positive and gram negative bacteria. The antioxidant activity of methanolic
and ethanolic extract of plant using DPPH model showed 84.32% and 82.54% respectively. Total
phenolic contents of both extracts showed 2.565g (GAE)/100g and 1.612g (GAE)/100g was noted,
respectively. Measured values of all these constituents explain strong anti-oxidant activity of the
plants. HPLC analysis of plant extracts exhibit promising concentration of phenolic contents.
Further the antibacterial activity indicates best possible use of this plant extract against infectious
diseases in addition to diseases associated with oxidation process.
Key Words: Antioxidants, free radical, HPLC, antibacterial activity, total phenolics, swertia
charata.

<strong>Abstract</strong>: The essential oils obtained from aerial parts of Daucu reboudii Coss. (Apiaceae)
which is endemic to north Africa collected from National Park of Gouraya (Bejaïa, Algeria) were
analyzed by GC/MS. 28 compounds were identified accounting for 97.8% of the total oil, the result
