Traditional Uses (Table 1)
The Barleria prionitis leaves and flowering tops are reported to rich in potassium salt . Preliminary phytochemical analysis of hydromethanolic extract of B. prionitis whole plant indicated presence of flavonoid, glycoside, saponin, tannins and steroid . Phytochemicals isolated from B. prionitis such as balarenone, pipataline, lupeol, prioniside A and Prioniside B . Glycoside are isolated from the areal plant are barlerinoside, verbascoside, shanzhiside methyl ester, 6-0-trans-p-coumaroyl-8-o-acetylshanzhiside methyl ester, barlerin, acetylbarlerin and 7- methoxy diderroside. Chromatographic examination of the alcoholic extract of the leaves and stems of Barleria prionitis Linn, revealed the presence of iridinoid glycosides such as acetyl barlerin and barlerin [9,21,15]. The leaves were reported to contain scutellarein, melilotic acid, synergic acid and 6-hydroxyflavones . β-sitosterol, scutellarein 7- neohesperidoside and apigenine 7-O-glucoside are present in B. Prionitis. Two new anthraquinones compound isolated from Barleria prionitis and characterized as 1,8, dihydroxy-2,7-dimethyl 3,6-dimethoxy anthraquinone,1,3,6,8-tetra methoxy-2,7-dimethyl anthraquinone.
Preliminary phytochemical analysis of hydro-methanolic extract of B. prionitis whole plant indicated the presence of glycosides, saponins, flavonoids, steroids and tannins . The leaves and flowering tops were reported to rich in potassium salts . Several phytochemicals viz., balarenone (1), pipataline (2), lupeol (3), prioniside A (4), prioniside B (5) and prioniside C (6) has been isolated from the ethanolic extract of B. prionitis . Numbers of glycosides include barlerinoside (7), verbascoside (8), shanzhiside methyl ester (9), 6-O-trans-p-coumaroyl-8-O-acetylshanzhiside methyl ester (10), barlerin (11), acetylbarlerin (12), 7-methoxydiderroside (13), lupulinoside (14) has been also isolated from the aerial parts . Two anthraquinones derivatives has been also identified in this plant and their structures were characterized as 1,8, dihydroxy-2,7-dimethyl 3, 6-dimethoxy anthraquinone and 1,3,6,8-tetra methoxy-2,7-dimethyl anthraquinone . The leaves were reported to contain scutellarein (15), melilotic acid (16), syringic acid (17), vanillic acid (18), p-hydroxybenzoic acid (19), 6-hydroxyflavones (20) . Beside these phytochemicals, luteolin-7-O-β-D-glucoside (21), β-sitosterol (22), scutellarein 7-neohesperidoside (23), apigenin 7-O-glucoside (24), 13, 14-seco-stigmasta-5, 14-diene-3-a-ol (25) were also reported to present in B. prionitis  (Figure 2).
The antidiabetic activity of alcoholic extract of leaf and root of B. prionitis was evaluated by using alloxan monohydrate. B. prionitis leaves showed significant decrease in blood glucose level, glycosylated hemoglobulin and significant increase in serum insulin and liver glycogen level. B. prionitis root showed moderate but non-significant anti-diabetic activity in experimental animals .
Butanol fraction of B. prionitis leaves showed significant anti-diarrheal activity. In vivo study showed that the butanol fraction dose dependently inhibited the castor oil induced diarrhea and PGE2 induced enter pooling in sprague-dawley rats. The butanol fraction also reduced the gastrointestinal motility in response to charcoal-induced gut transit changes .
Diuretic activity of B. prionitis flower extract was investigated using by administration of normal saline solution. Administration of aqueous flower extract was significantly increased the urination and sodium elimination but not potassium in rats. The diuretic effect of flower extract was comparable and significant with the reference drug furosemide .
Alcoholic extract of roots and leaves oft of B. prionitis did not showed any toxic effect in adult albino rats. During the 14 days of study period death was not observed on oral administration of extract . Using different dose of iridoid fraction in the safety evaluation and maximum tolerance dose study the oral LD50 with no signs of abnormalities or any mortality observed .
Maximum protections were found to be 66.26%and 59.42% by iridoid fraction (200 mg/kg) in PL induced ulcer and CRS-induced ulcer rat model. Iridoid fraction from leaves reduced ulcer index . In ethanol induced gastric ulcer rat model, methanolic extract of leaf (500 mg/kg bw) and ranitidine provided 67.7and 75.5% inhibition of ulcer. Same dose of extract and drug displayed 70.3 and 62.2% inhibition in indomethacin induced gastric ulcers model. Extract also showed efficacy against indomethacin induced gastric mucosal damage and increased liver enzymes in ethanol induced ulcer rat model .
It is evident from different studies that B. Prionitis potentially carries medicinal properties and in India it has been traditionally used to cure various ailments. As per the studies of [10,11,14] refer (Table 1) leaves of B. Prionitis can be used to cure skin diseases, scabies, glandular swellings etc. if applied directly as paste or juice given orally (as mentioned specifically in Table 1). Similarly, according to the studies of [11,16] and other authors (Table 1) Stem, root flower and whole plant can be used to treat various diseases like viral fever, rheumatic fever whooping cough, Edema etc. In the present study author has mentioned the case studies of 30 patients getting relief from renal stones when they were advised to take a paste of leaves orally followed by glass of butter milk for 3 days in continuation and more than 70% patients got relief within fortnight. This proves its amazing diuretic property and other medicinal properties makes B. Prionitis a special medicinal plant while it is still merely known to common PR actioners and pharmacists as well.
Besides, the phytochemical analysis of various parts of the plant also indicated the presence of glycosides, saponins, flavonoids, steroids and tannins . The leaves and flowering tops were reported to rich in potassium salts  and other important phytochemicals (Table 2) has been reported by different scientists.
Moreover, anti-diabetic activity, antidiarrheal activity, anti-toxicity and Gastro protective activities has also been mentioned when tested on rats by different workers as mentioned in above paragraphs.
Hence, present review about amazing medicinal properties of B. Prionitis as suggested and reported by various authors will be helpful to disseminate the knowledge among practitioners, pharmacists and other workers and opens a gateway for further studies on the basis of existing scientific reports.
In the present studies it has been found that B. Prionitis has tremendous medicinal properties and can be used as potential drug in various combinations to cure many diseases. Though it is a very commonly found herbal plant in almost every part of Asia but still its significant properties are rarely known and undiscovered. Hence further research is suggested to understand its pharmacological importance against numerous diseases and to identify its phytochemical metabolites. So that it can be used efficiently in pharmaceutical industry.
