The whole plant of the methanolic extract from Leucas cephalotes was screened for invitro antioxidant (using the DPPH method), invivo analgesic (using hot plate test in mice) and anti-inflammatory (using rat paw edema test) activities. The methanolic extract of Leucas cephalotes (MELC) scavenged the DPPH radicals in a dose-dependent manner. The IC50 value to scavenge DPPH radicals was found to be 421.3µg/ml. A significant (p<0.0005) analgesic activity was observed at 60 min with 200 mg/kg, and 400 mg/kg exhibited maximum activity. The maximum anti-inflammatory response was produced at 3 hr and 2 hr with doses of 200 and 400 mg/kg, respectively. These results suggest that the methanolic extract from Leucas cephalotes exerts significant analgesic and anti-inflammatory effects, which were comparable with standard drugs.

Evaluation of Anti-inflammatory Activity of Alcoholic Extract of Leaves of Leucas Aspera in Albino Rats2014 •
Objective: Alcoholic extract of leaves of Leucas Aspera was tested for anti-inflammatory activity in animal models. Methods: Three doses, 100 mg/kg, 200 mg/kg and 4 00 mg/kg of the plant e xtract prepared as a suspension in 1% tween 80 in normal saline. The control group received only Tween 80 (2%, v/v) orally . Acute and sub - acute inflammatory activities were studied in rats by ca rrageenan induced paw edema and cotton pellet induced granuloma models respectively. In both models, the standard drug used was diclofenac 15 0 mg/kg. Results: All the three test doses (100mg/kg, 200mg/kg,400mg/kg) at different time intervals(0 - 4 hours) did exhibit anti- nflammatory activity in both models ie. Carrageenan model and cotton pellet granuloma model in comparison to control.The test dose of 400mg/kg of leucas aspera produced a percentage inhibition of 60.64%which was comparable to standard drug Diclofenac which produced a percentage inhibition of 60.70% in carrageenan model, whilst the per...
Leptadenia reticulata was reported to be used for several medicinal purposes. The present study was undertaken to evaluate anti-inflammatory, analgesic and lipid peroxidation inhibition activities of L. reticulata. The anti-inflammatory assay was performed by λ-carrageenan and formalin induced paw edema test. Pro inflammatory mediators (IL2, IL6, TNF-α) in serum of treated and control organism were analyzed by quantitative ELISA. Lipid peroxidation inhibition was measured by thiobarbituric acid reactive substances (TBARS) assay. Analysis of the most active fraction revealed the presence of one phenolic compound (p-coumaric acid), two flavonoids (rutin and quercetin) which also determined quantitatively. The ethyl acetate fraction at 600 mg/Kg significantly inhibited λ-carrageenan and formalin induced paw edema by 60.59% and 59.24% respectively. Notable reduction in percentage of writhing (76.25%), induced by acetic acid signifies the potent analgesic activity. Lower level of pro-inflammatory cytokines (IL-2, IL-6, TNF-α) in serum at the 4 th hour of λ-Carrageenan injection indicated the inhibition of cyclooxigenase-2 (Cox-2), Nitric oxide (NO) and release of prostaglandin to prevent inflammation. The study also demonstrated the decrease in malonaldehyde (MDA) concentration which revealed the lipid peroxidation inhibition potential of the plant. Our finding provides evidence for potent biological activities in tested model which is supported by its characterized bioactive compounds and ethnomedicinal relevance.
Medicinal plants are widely used as alternative medicines for the treatment or prevention of many diseases. Traditionally, Leucas cephalotes is used for the treatment of asthma, pain, bronchitis, inflammation, dyspepsia, paralysis, jaundice, diarrhea, wounds and fever. To qualitatively evaluate the profile of phytochemical constituents as well as acute toxicity, analgesic and antidiarrheal activities of ethanol extract of Leucas cephalotes leaves, the present study was designed. Phytochemical constituents, acute toxicity, analgesic and antidiarrheal activities were determined and assessed by various tests such as Molisch's test, Fehling test, Mayer's test, frothing test, FeCl3 test, alkali test, Salkowski's test, Keller-killiani test and CuSO4 test, OECD guidelines, formalin induced paw licking, acetic acid induced writhing, castor oil and MgSO4 induced diarrheal test. This extract figured the presence of carbohydrates, flavonoids, tannins, glycosides, triterpenoids, fat and fixed oils. Behavioral changes, mortality or sign of any toxicity were not observed up to the dose as high as 4000mg/kg. The crude extract was found to have significant (p<0.05, vs. control) analgesic activity at the oral dose of 200 mg/kg and 400 mg/kg (b. wt.) in the tested animals. Moreover, both doses of (200 mg/kg and 400 mg/kg) ethanol extract significantly (p<0.05, vs. control) reduced the gastro-intestinal motility and inhibit the percentage of diarrhea in antidiarrheal models. But 400 mg/kg dose showed better analgesic and antidiarrheal activity than 200 mg/kg dose compared to control. The results indicate that Leucas cephalotes leaves may provide a potential source of analgesic and antidiarrheal activities.
Leucas cephalotes rainy season weed and has been traditionally used as mild stimulant, diaphoretic and used in fever and liver disorder. The present study was carried out to investigate morphological, microscopical, physicochemical and phytochemical screening of whole plant. Morphological studies of leaves, stem, root, flower and seed showed the presence of various diagnostic characters. In the microscopical studies, leaves showed the presence of vascular bundle, sessile glandular trichomes, palisade and anomocytic stomata. Prismatic calcium oxalate, pericycle, bicollateral vascular bundle with non distinct cambium was found in stem. Secondary xylem was abundant in root. Ash value, extractive value, foreign organic matter and moisture content was determined for quality standard of drugs. The powdered drugs were defatted with petroleum ether and successively extract with different polarity solvent. Phytochemical investigation shows the presence of flavanoids, phenol, phytosterol and tannins. The result of the study could be useful for identification and preparation of monograph of the plant.

Leucas aspera commonly known as 'Thumbai' has a wide variety of medical applications. The aqueous extract of Leucas aspera (leaf extract) was assessed for its various in vitro activities such as anti-inflammatory, anti-helminthic, anti-arthritic, anti-oxidant and anti-bacterial activity. The in vitro Anti-inflammatory activity was studied by human red blood cell (HRBC) membrane stabilization method by using various concentration of L. aspera. The results showed that the HRBC Membrane stabilization activity of the aqueous leaf extract of L. aspera at concentration of 100μg/ml showed 73.25% inhibition of denaturation in hypotonic solution while the standard Diclofenac 100μg/ml showed 79.25% inhibition of denaturation. The crude extracts of the leaves of Leucas aspera showed statistically significant anti-inflammatory activity in in vitro assay.The crude aqueous leaves extract of Leucas aspera also showed that significant anti-helmintic effect causing death of the worm at all the concentrations but the time of death was different in each case. Invitro anti-arthritic activity was carried out by bovine serum protein denaturation method and egg albumin denaturation method. The results suggested that the aqueous extract of L. aspera showed a very good anti-arthritic activity. Antioxidant and Antibacterial activity was also evaluated. The present study concluded that the plant can be formulated in broad spectrum antibiotics and also confirms the traditional uses in pathogenic disease.
