Abstract: Background: Cow urine has been widely used as therapeutic or additive agents in different parts of Nepal, mainly to treat infections, cuts, burns, etc. Cow urine has been considered as sacred and holy water and used in many rituals and worshipping purposes. Apart from therapeutic and rituals ceremony cow urines are also used in purification and disinfecting the houses. Objective: The aim of the study was to investigate the in-vitro antioxidant and antibacterial activity of cow urine from different altitudes across Nepal. Materials and Methods: Antioxidant activity of cow urines was carried out by using 2,2-Diphenyl-1-picrylhydrazyl (DPPH) as free radicals. The antibacterial activity of cow urines was tested by the agar disc diffusion method against Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive). Results: The urine s le from Muktinath (Subalpine region) showed the highest 44.8±0.21% inhibition against DPPH free radicals. The urine s les from Jajarkot and Marpha (Temperate zone) showed 39.70±0.43% and 37.30±0.15% inhibition against DPPH free radicals respectively. The urine s les from Palpa and Shyangja (Subtropical region) showed 30.00±0.24 and 34.4±0.01 percent inhibition of DPPH radicals. The s les from Butwal and Dhangadhi (Tropical region) showed the least percentage inhibition of 23.9±0.08 and 21.12±0.1 respectively. Amongst the entire s le, the subalpine region of cow urine (Muktinath 3710m) made known the highest inhibition zone such as 10.56±0.05mm against S. aureus and 7.46±0.15 against E.coli. Conclusion: Our study has concluded that cow urines have the antibacterial and antioxidant activities and vary in potency according to altitudinal and climatic differences. Hence cow urine from the subalpine zone has better antibacterial and antioxidant activity than that of lower altitudinal climatic zones.

Abstract: Garugapinnata Roxb. (Burseraceae) is a medium-sized tree widely available all over the tropical regions of Asia. Bryophyllum pinnatum (Lam) Oken. (Crassulaceae) is an indigenous and exotic plant grown in tropical regions. Both plants have been used for their anti-inflammatory, antioxidant, anticancer, wound healing, antidiabetic activities, etc. This investigation was designed to explore the result shown by methanolic extract of Garuga pinnata bark and Bryophyllum pinnatum leaves, on cognitive power and retention of the memory in experimental mice along with quantification of phenolic compounds and DPPH radicals neutralizing capacity. The memory-enhancing activity was determined by the elevated plus-maze method in Scopolamine-induced amnesic mice, using Piracetam as allopathic and Shankhpushpi as ayurvedic standard drugs. Two doses (200 and 400 mg/kg p.o.) of both extracts were administered to mice up to 8 consecutive days transfer latency of in idual group was recorded after 45 minutes and memory of the experienced things was examined after 1 day. DPPH assay method and the Folin–Ciocalteu method were employed to determine antioxidant potency and total phenol amount, respectively. 400 mg/kg of the methanolic B. pinnatum bark extract significantly improved memory and learning of mice with transfer latency (TL) of 32.75 s, which is comparable to that of standard Piracetam (21.78 s) and Shankhpushpi (27.83 s). Greater phenolic content was quantified in B. pinnatum bark extract (156.80 ± 0.33 µg GAE/mg dry extract) as well as the antioxidant potency (69.77% of free radical inhibition at the 100 µg/mL concentration). Our study proclaimed the scientific evidence for the memory-boosting effect of both plants.
