T. amplexicaule Roth. has been investigated phytochemically for biologically active constituents from the benzene extract. This yielded a mixture of terpenoids: beta-sitosterol, alpha-amyrin, lupeol, hexacosanoic acid, ceryl alcohol and hexacosane. The sequential extracts, isolated terpenoids and reference antibiotics were screened for their possible bioactivities against selected pathogenic bacteria, Escherichia coli, Staphylococcus aureus and fungi, Aspergillus flavus and Penicillium chrysogenum etc. Out of the sequential extracts, the benzene extract was more potent against S. aureus (IZ = 10.36) and R. phaseoli (IZ = 10.69). The inhibition zones of isolated terpenoids were also recorded and the activity index was calculated and it was found that hexacosane was more active (IZ = 13.39) against E. coli and hexacosanoic acid had greater activity against A. flavus (IZ = 11.56). The present study deals with antimicrobial screening of sequential extracts and isolated terpenoids.

Background and Aim Oral feeding following variceal ligation in cirrhotics is usually delayed due to fear of rebleeding. Solid diet is usually further delayed (until 72 h) despite lack of evidence. We aimed to compare the impact of early versus delayed feeding on rebleeding following variceal ligation. Methods This was a prospective randomized controlled trial including patients undergoing variceal ligation for active esophageal variceal bleeding. Patients were randomized into two groups. In the early‐feeding group, liquid diet was given after 1 h following variceal ligation and a regular solid diet was resumed after 4 h. In the delayed‐feeding group, patients fasted for the first 4 h after variceal ligation, liquid diet was given until 24 h, soft diet for the next 48 h and a regular solid diet after 72 h. Results There were 52 and 49 patients in the early and delayed feeding groups, respectively. Very early rebleeding rates [2 (3.84%) vs 1 (2.04%); P ≥ 0.99] and delayed rebleeding rates [2 (3.84%) vs 4 (8.16%); P = 0.75] were similar in both groups. Protein and calorie intake in the early‐feeding group was significantly better and early infections in active bleeders were significantly lower compared to the delayed‐feeding group. One‐month mortality was similar in both groups [3 (5.76%) vs 4 (8.16%); P = 0.75]. Conclusion Early feeding with a regular solid diet in conscious patients after successful variceal ligation for esophageal varices is safe, provides better nutrition and results in lower incidence of infections in bleeders compared to delayed feeding.
