ABSTRACT
Bakuchi (Psoralea corylifolia Linn.) is one of the important endangered medicinal plants used in Ayurveda and other Traditional systems. Its cultivation and propagation is difficult due to its low germination rate (5-7%) & prolonged seed dormancy. Bakuchi seeds made into 5 groups, the experiment was conducted in a complete randomized block design with 5 treatments and 5 replications totally 500 seeds in each group) & observed for 50 days. Control Group 1 no- seed treatment, Group 2- Standard treated with 1% conc H2SO4, Group 3 Vrikshayurvedic treatment done by soaking in milk subsequently fumigation of Vidanga & Ghee, Group 4- treated with paste of Brihati, Tila, Kamalanaala, Ghee & Group 5 treated by soaking in milk subsequently Cow dung, Vidanga & Honey applied. Number of seeds germinated, germination percentage, emergence index and relative seed germination parameters were observed. HPLC studies carried out of post harvested Bakuchi seeds of all 5 groups to know the effect of seed treatments on Psoralen content quantitatively. Overall results indicates that Group 4 (8.000 ± 0.8367) seeds soaked in 12 hrs milk followed by application of Brihati, Tila, Kamalanaala & Ghee paste for 12 hrs treatment is statistically significant (P value>0.05) in comparison with group 2 (4.600 ± 0.6782) Sulphuric acid treatment and Group 3 (4.200± 0.9165) fumigation with Honey & Vidanga. Rest of the groups shown insignificant changes on germination parameters. HPLC Results found that generally seed treatments may reduce the content of Psoralen as in control (Group 1) maximum percentage (0.04%w/w) of Psoralen is noticed. Among treatment groups Group 4 contains maximum (0.027%w/w) Psoralen next to control (0.039%w/w). Psoralen content is very less in standard Group 2 (0.022%w/w), Group 3 (0.023%w/w) & Group 4 (0.024%w/w). Maximum germination percentage was observed in Group 4 in comparison with the Group 2conventional method of treating with sulphuric acid. Estimation of Psoralen contents in the seeds from the plants grown by various treated seeds reveled that Group 4 is qualitatively better than standard, but inferior to the control, standard & other Vrikshayurveda seed treatment techniques used in the current experiment.
ABSTRACT
Background: Saraca asoca (Roxb.) Wilde (Fabaceae) is a high valued but vulnerable medicinal plant of Western Ghats region. This plant is mainly known for its use in various gynecological disorders. Objective: The objective of the present study was to investigate seasonal variation of the polyphenolic compounds viz., epicatechin and gallic acid in the bark of S. asoca by using Reverse Phase High Performance Liquid Chromatography‑Diode Array Detector (RP‑HPLC‑DAD) method. Materials and Methods: The bark was collected in six different Ritu (season) viz. Varsha (monsoon), Sharad (autumn), hemant (early winter), Shishir (winter), Vasanta (spring), and Grishma (summer) mentioned in Ayurveda. Results: The RP‑HPLC‑DAD analysis indicated that levels of epicatechin and gallic acid in the bark of S. asoca vary seasonally. The highest concentration of epicatechin was observed in Shishir Ritu (3315.19 ± 165.76 mg/100g) and gallic acid during Hemant Ritu (211.90 ± 10.60 mg/100 g). Conclusions: In present study, the ability to synthesize and accumulate both the compounds in bark of S. asoca varied greatly throughout the seasons. It was also observed that the compound epicatechin was present abundantly as compared to gallic acid throughout the seasons.
ABSTRACT
Peptic Ulcers are the most common condition experienced by most of the people due to urbanized lifestyle. Hemidesmus indicus R.Br. is a herbal drug mentioned for its treatment in the ancient Indian traditional medicine. To compare the Prophylactic and Curative effects of aqueous and Alcoholic extracts of Hemidesmus indicus in Drug induced ulcers. Aqueous and Alcoholic extracts of the drug were studied for their ulcer healing activity in Wistar Albino rats. Ninety Wistar albino rats were divided into nine groups with one control, four prophylactic and four curative groups. Ulcers were induced with Indomethacin in a dose of 20 mg/kg body weight twice in a gap of 15 hours. Aqueous extract was given in a dose of 500 mg/kg body weight and alcohol in a dose of 100 mg/kg body weight. It was found that both have potential ulcer healing activity with alcoholic extract marginally better than aqueous extract. It can thus be concluded that Hemidesmus indicus R. Br is a effective drug in peptic ulcers.
