ABSTRACT
Anaphalis neelgerriana DC. and Cnicus wallichii DC. belonging to the family Asteraceae [Compositae] were selected to evaluate antimicrobial and wound healing activity. These two valuable medicinal plants are indigenous to Nilgiris, Tamilnadu, South India. These plants are used by the tribals of Nilgiris in skin infections, cuts, wounds and abscesses. Seven different extracts were obtained from the aerial parts of each plant and screened for in vitro antimicrobial and in vivo wound healing activity studies by excision method. Significant antimicrobial activity was found in aqueous, 50% methanol, and methanolic extracts of both the plants. Ethyl acetate extract of Anaphalis neelgerriana DC. produced significant antimicrobial activity. The extracts were prepared as 0.2% w/w emulsifying ointment and subjected to wound healing activity studies and compared with the standard 0.2% w/w Nitrofurazone ointment. The ethyl acetate extract of Anaphalis neelgerriana DC produced a significant wound healing activity. The animal groups which exhibited wound healing activity were subjected to histopathological studies

The leaves and stems of Cnicus wallchii DC family Asteraceae [Compositae] were studied to determine the pharmacognostical standards. The investigation was carried out on macro and microscopical characters of leaf and stem, powder microscopy, fluorescence analysis, leaf constants like vein islet number, vein termination number, stomatal number, stomatal index and study of physical constants like ash values, extractive values and preliminary phytochemical evaluation

Anaphalis neelgerriana DC belonging to the family Asteraceae [Compositae] commonly known as Helichrysum. It is an important medicinal plant indigenous to Nilgiris, Tamilnadu, South India. Different extracts were obtained from the aerial parts of the whole plant and subjected to pharmacological investigations. Since the related species Anaphalis morisannicola was reported for its anti-cancer activities, In vitro screening studies for anti-tumour and antioxidant activities were carried out. Preliminary phytochemical evaluation, fluorescence analysis of the different extracts and aerial parts powder, physical constants like ash values, extractive values were also determined

The cones of Cupressus sempervirens Linn, belong to the family Cupressaceae were collected from Government Botanical Garden, Ootacamund and dried under shade. The dried cones were powdered and used for physico-chemical constants determination. The macroscopical and microscopical characters were also evaluated [by using fresh cones] and reported. The anatomical parameters of the cones were studied first time on this plant

The methanol extracts of Mahonia leschenaultii Takeda [Berberidaceae] root and root bark were tested for antibacterial potential against Escherichia coli [NCIM 2068], Pseudomonas aeruginosa [NCIM 2053], Staphylococcus aureus [NCIM 2492] and Staphylococcus epidermidis [NCIM 2493], on nutrient agar medium and nutrient broth using ampicillin trihydrate as standard drug. For antifungal study strains used were Trichophyton lignorum [NCIM 1195] and Candida crusei [NCIM 3129], on Sabourauds dextrose agar [SDA] and Sabourauds dextrose broth [SDB] by cup plate method using amphotericin B as standard drug. The results showed that all extracts exhibited significant activity against all the selected strains of bacteria and relatively more against Staphylococcus epidermidis. The antifungal activity was less significant when compared with antibacterial activity
