Background Herbal medicinal material and product need is increasing, and with this increase in the need, it is very much an essential requirement to maintain the quality of them. Main body The quality of the herbals is altered by various physical, chemical, and geographical aspects which contribute to the quality of these materials. Apart from that, adulteration is also an increasing concern when it comes to herbal material quality. Various chemical and phytochemical test, analytical techniques, and hyphenated analytical techniques are used for determining the quality aspects of the herbal materials in the herbal pharmaceuticals. Conclusion These techniques can be used as quality control tool in assessing the quality of herbal materials and herbal pharmaceuticals.

In spite of tremendous advances in the field of medicine, there is no truly satisfactory drug for the treatment of renal calculi. In the present study, the efficacy of the root bark of Moringa oleifera Lam. (Moringaceae) as an antiurolithiatic agent was investigated using an experimentally induced urolithiatic rat model. Hyperoxaluria was induced in rats using 0.75% ethylene glycol in water. Aqueous (AqE) (200 mg kg −1 body weight) and alcoholic extracts (AlcE) (200 mg kg −1 body weight) of the root bark of M. oleifera were given orally in curative and preventive regimens over a period of 28 days. Both the extracts significantly (P < 0.001) lowered the urinary excretion and kidney retention levels of oxalate, calcium and phosphate. Moreover, elevated serum levels of urea nitrogen, creatinine and uric acid were significantly (P < 0.001) reduced by the extracts. The results were comparable with the standard drug, cystone (750 mg kg −1 body weight). The reduction of stone forming constituents in urine and their decreased kidney retention reduces the solubility product of crystallizing salts such as calcium oxalate and calcium phosphate, which could contribute to the antiurolithiatic property of root bark of M. oleifera.

Background:Āmalaki (Embelica officinalis Gaertn.) is one of the most celebrated herbs in the Indian system of traditional medicine. It is one of the best Rasāyana-s (health promoting) drug. In Dugdhāmalakyādi yoga, Āmalaki (Embelica officinalis Gaertn.) powder is administered along with milk in case of svarabhaṅga (hoarseness of voice). Here an attempt is made to convert this formulation into chewable tablet without altering its property to improve its palatability, shelf life and fixation of proper therapeutic dose.Methodology:Chewable tablets were prepared by wet granulation method. Here, Āmalaki powder was prepared initially and it was mixed with additives and preservatives. Granules were prepared from this mixture by adding binding agent, finally compressed in to tablets.Results and Conclusion:The physico-chemical analysis of Āmalaki standard are: Foreign Matter-Nil, Acid insoluble Ash-0.51%w/w, Water soluble Ash-2.01% w/w, Alcoholic Extractives-44.48%, Aqueous Extractives 67.52%, pH-3.1, Moisture content-8.19%. Quality control test for chewable tablet was carried out and found satisfactory with general characteristics of tablet viz. hardness 1.8, disintegration time 15-20 min, friability 0.5%, weight variation +/- 3%. The TLC of Āmalaki powder showed 3 spots with Rf value 0.14, 0.4, and 0.73 and the chewable tablets showed 2 spots with Rf value 0.31 and 0.89 under 254 nm. The adaptation of modern techniques or methods to convert the Ayurvedic formulations without altering its therapeutic property is necessary to made them suitable for the present trends of newer drug delivery dosage forms.

Development and modification of Ayurvedic classical formulations into widely acceptable dosage forms is an important area to be focused in the present era. The designing of liquid dosage form has generally been emphasized on the basis of ease of administration to those individuals who have difficulty in swallowing solid dosage forms, specially in pediatric and geriatric group. Churna (powders) are the preferentially administered Ayurvedic formulations by oral route. Most of these powders are hygroscopic, bitter to taste and should be administered with suitable vehicle. Avipattikara Churna is one of the unique formulation widely practiced in the management of common ailments like Amlapitta (hyperacidity), Vibandha (constipation), Agnimandya (loss of appetite), Arsha (hemorrhoids). Modification of the classical Churna (solid dosage form) into a more acceptable and convenient syrup (liquid dosage form) with modern pharmaceutical methods and its physico-chemical analysis is the main aim of the study. In the present study Avipattikara syrup was developed with 66.7 % w/V of Khandasharkara (sugar candy powder) without any pharmaceutical additives. Physicochemical analysis, microbial limit test, and physical quality tests for Avipattikara Churna and syrup were carried out respectively. Results suggest that, the developed syrup had a quality of ideal syrup.
