Evaluation of the antioxidant activity of the Ephedra alata species
Ephedra alata is an endemic Algerian plant with pharmacological potential, used for centuries in traditional medicine. Herein the antioxidant activity of E. alata was assessed in order to validate its traditional use in Algerian folk medicine for the treatment of different aliments. The antioxidant activity of its aqueous extract was evaluated by different assays including, DPPH, reducing capacity, and β-Carotene Bleaching Assays. E. alata aqueous extract seems to have moderate reducing capacity with EC50 of 578,16 μg/mL, and an average scavenging effects with respect to the DPPH radical with IC50 of the order of 276 μg/mL. However, we found that aqueous extract of E. alata possess a remarkable antioxidant activity against the bleaching of β carotene (77%). These results suggest that the extract of E. alata has a considerable capacity to react with free radicals to convert them into non-reactive species and to interrupt the chain of radical reactions. It also reflects the solubility of the antioxidant compounds of the extract in water. Compounds that possess this characteristic can be used in food systems. Obtained results suggest that aqueous extract of Ephedra alata could provide powerful natural; antioxidant, agents, to be used in the management.
Isolation identification and histopathological examination of Pasteurella infection in Respiratory tract of slaughtered Buffalo in Unnao and Barabanki District of Uttar Pradesh
In order to investigate the bacteriological infection in the respiratory tract, lung lesions were examined in 34 patients (37.77%) from Unnao and 26 cases (28.88%) from Barabanki districts. The identification of thirty-four isolates as Pasteurella spp. was based on their morphology, cultural/colony characteristics, and biochemical properties, such as the production of catalase, urea hydrolysis, citrate consumption, and indole. In Unnao and Barabanki district, emphysematous lung was found in 8 cases (8.88%) and 6 cases (6.66%) of lung lesions, respectively, and congestion with hemorrhagic lesions in 14 cases (15.55%) and 11 cases (12.22%). The lung slaughtered in Unnao and Barabanki district showed two cases (2.22%) of hard nodular growth/granulomatous lesions and one case (1.11%) of nodular lesions. The percentage of cases in each district that had pulmonary oedema was 6 (6.66%) and 5 (5.55%). In both districts during the study period, the highest number of cases of lung congestion and hemorrhages were followed by emphysematous conditions and pulmonary oedema in the slaughtered animal. Microscopic views show that significant emphysema can occasionally be observed in addition to vascular and bronchiolar congestion. The lungs grossly characterized as having pulmonary emphysema upon histopathological investigation showed blood vessel congestion, ruptured alveoli resulting in the creation of giant alveoli. Tissue sections were also stained using the MacCallum-Goodpasture staining procedure in order to demonstrate the organisms, and twenty lung tissues were found to have red coccobaccilli organisms. In pneumonic lungs, mild to moderate fibrosis was seen. Mallory Heidenhain and Masson's trichome staining revealed fibrous tissue as blue. Therefore, because of pasteurellosis, unwell buffaloes are killed in slaughterhouses for human consumption; the flesh from these animals should not be eaten or may be declared ineligible due to illnesses.
BEHAVIOUR OF BRINJAL GENOTYPES UNDER DIFFERENT LEVELS OF SOIL SALINITY
The present investigation was conducted at Vegetable Research Farm, Department of Vegetable Science, Punjab Agricultural University, Ludhiana during 2017-18 and 2018-19. It has been observed that yield contributing factors i.e. fruit length, fruit diameter, number of fruits per plant and fruit yield was decreased as the salinity level increased. On the basis of evaluation, brinjal genotypes SL-8-PB-1-3-1-4 followed by KBSR-343-1 and BL-215 performed better upto 4 ds/m levels of salinity with a slight decline in yield traits, but at 6 ds/m yield was drastically reduced, which was 12%, 28% and 28.5% respectively as compared to control. Number of days to first flowering and 50% percent flowering was increased as the salinity level increased because salt effects the procedure of flower blooming. It is concluded from the investigation, SL-8-PB-1-3-1-4 (Small Long), KBSR-343-1 (Round) and BL-215 (Long) emerged as ideal genotypes for salt tolerance under field and pot conditions.
Bio-active essential oil components in small cardamom as influenced by weather elements
The present investigation was performed to evaluate the variability in the yield and bio-active components of Indian cardamom seed extract from two different ecological zones of the Western Ghats (Pampadumpara and Madikeri regions), India. Results showed significant differences in the yield and bio-active components in two varieties viz. Appangala-1 and PV-2. The variety PV-2 (639 g/plant) recorded significantly higher yield in Pampadumpara than Madikeri (399 g/plant). Significant variability was observed in the bio-active components of the essential oil. The intrinsic quality of cardamom is mainly attributed to two important components α-terpinyl acetate and 1,8- cineole. The highest range of α-terpinyl acetate in both the varieties (41.1-42.4%) under Madikeri region was recorded followed by Pampadumpara region (35.01-40.2%), while the 1,8-cineole content showed highest in Pampadumpara (25.68-37.57%) followed by Madikeri (23.06-32.66%) region. The highest content of linalool, α-terpineol, linalyl acetate and cis-geraniol was recorded in PV-2. The highest content of β-neralidol was recorded in Appangala-1. The variation among the region was significant for terpinen-4-ol, β-myrcene and β-neralidol. Pampadumpara region received 47% and 18% more rainfall during North east monsoon (October to November) and summer shower (December to May), respectively though received less rainfall during South west monsoon (71%) and also showed 10% more rainfall distribution compared to Madikeri region. The annual mean maximum temperature (Tmax) was 18% more in Madikeri compared to Pampadumpara region. With all the environment factors taken into account, Pampadumpara region is relatively better in terms of cardamom capsule yield and Madikeri region for bio active components which attributes intrinsic quality of capsules.
STUDIES ON THE ECONOMIC TRAITS OF ERI SILKWORM REARED ON PRIMARY HOST PLANT IN RELATION TO SEASONAL VARIATIONS UNDER ODISHA CONDITION
India is the only country that produces all five commonly traded varieties of natural silk: Mulberry, Eri, Muga, Temperate tasar, and Tropical tasar. Eri silk is the type of silk produced by Samia ricini. Eri silk is often referred to as Non-Violence silk or Peace silk. It is also known as "Poor Man’s silk." We studied how several seasons impact the rearing performance of Eri silkworms by analyzing multiple larval parameters (larval duration, pupal duration, fecundity, hatching, ERR%, emergence rate and survival rate) and cocoon parameters (cocoon weight, shell weight, and shell %). The current research has been conducted using the tray rearing method, which involves placing castor leaves over the worms on wooden trays. This study examines the economic significance of cocoon and post-cocoon characteristics of eri silkworms raised in various seasons. The research showed that economic traits of eri silkworm were most pronounced in autumn and spring season under Odisha climatic conditions.
