RESUMEN

Chirabilvadi Yoga is a combination of four drugs Chirabilva, Arjuna, Jyotishmati and Kakanasa in powder form, each of these ingredients has solid base of previous experimental studies for their individual analgesic activity. Bhavana (trituration) is an important Samskara (process) mentioned in Ayurvedic classics by which drug may be made very potent to produce a positive results. Till date no data available on this combination Bhavita Chirabilvadi Yoga triturated seven times with Chirabilva Patra Swarasa and made dried powder. Present study is to screen the differences in pharmacognostical and pharmaceutical profile of the Chirabilvadi Yoga before and after Bhavana. After Bhavana significant changes were found in the pharmacognostical parameters like deformated rosette crystals and cluster crystal of Arjuna and broken stone cells of Arjuna, which are rarely found before Bhavana of the drug and also evaluate the differences in the pharmaceutical profile before and after Bhavana like loss on drying, ash value, acid insoluble ash, water soluble extract, methanol soluble extract, pH and HPTLC.

RESUMEN

Os indicadores convencionais de fertilidade de solo, mais comumente utilizados, enfatizam o balanço ácido-base e o conteúdo de elementos químicos, mas não consideram adequadamente as propriedades biológicas do solo, responsáveis por grande parte do seu funcionamento. Os indicadores biológicos, ainda pouco difundidos, levam em consideração a atividade microbiana do solo que é mais sensível à dinâmica do solo. Em Marapanim-PA, e utilizando um desenho experimental inteiramente casualizado, com quatro repetições, avaliou-se o comportamento dos indicadores do solo carbono e nitrogênio da biomassa microbiana, fosfatase ácida, matéria orgânica, carbono orgânico e fósforo disponível, em um solo com cultivo sequencial de mandioca e milho, preparo com corte-e-trituração da capoeira original. Os fatores corte-e-trituração, fosfato natural e adubação verde foram arranjados nos seguintes tratamentos: capoeira; testemunha; fosfato natural (FN); feijão-de-porco [Canavalia ensiformis (L.) DC] (FP); FN + FP; FN + guandu [Cajanus cajan (L.) Millspaugh]. (G); FN + titônia [Tithonia diversifolia (Hemsley) A. Gray] (T); FP + G; FP + T. Em quatro épocas de amostragens, foram tiradas amostras compostas do solo (0 - 10 cm) de cada parcela para análise dos indicadores. Os indicadores estudados foram influenciados pela época de amostragem do solo. Os indicadores fosfatase ácida, nitrogênio da biomassa microbiana e carbono da biomassa microbiana foram capazes de detectar os efeitos de maior número de tratamentos de recuperação do solo testados, enquanto a matéria orgânica do solo foi o menos capaz. Ao longo do tempo, a resposta dos indicadores variou em função dos fatores estudados.


The more commonly used traditional soil fertility indicators emphasize the acid-basic balance and the content of chemical elements, but do not consider adequately the biologic soil properties, largely responsible for soil functioning. The biologic indicators, not yet sufficiently used, take into consideration the microbial activity that is more sensible to soil dynamics. This study was carried out in Marapanim-PA and using a completely randomized plot design, with four replications, to evaluate the behavior of some indicators such as microbial biomass, acid phosphatase, soil organic matter, organic carbon and available phosphorus - in a soil cultivated with cassava and corn, and in which the secondary vegetation was prepared by slash-and-trituration practice. The slash-and-trituration, rock phosphate and green manure factors were arranged in the following treatments: secondary vegetation; control; rock phosphate (RP); wonderbean Canavalia ensiformis (L.) DC (W); RP + W; RP + pigeonpea Cajanus cajan (L.) Millspaugh (P); RP + tithonia Tithonia diversifolia (Hemsley) A. Gray (T); W + P; W + T. In four season of sampling, soil samples were taken from the 0 - 10 cm layer of each parcel to measure the indicator values. The indicators studied were influenced by the time of soil sampling. The acid phosphatase, microbial biomass nitrogen and microbial biomass carbon soil indicators were capable of detecting the effects of a higher number of soil reclamation treatments, while soil organic matter was the least capable. With the passing of time, the response of the indicators varied according to the factors studied.
