“…Between the two antimicrobial activity analysis procedures of determining the length of the inhibition zone and colony count measurements, the more appropriate procedure needs to be identified. (22) An event of singular significance in the study was that the only orphaned part thus far evading any modern use or terminology related to the coconut palm was restored to its rightful place. Gobalu in Sinhala was named as 'very tender coconut'.…”

“…'Astringent Index' is the orderly listing of TAAEq values. (22) Tannic acid is considered as the reference substance since it is the predominant chemical compound that can be found on most astringent materials. According to our definition, if a particular sample has high astringency (protein precipitating ability) its astringent power in milliliters takes a low value.…”

“…It consumes a larger volume to precipitate the standard amount of egg albumin solution. (22) Although traditional Sri Lankan society has been practicing the folklore plant medicines for thousands of years, the validity and the scientific basis behind the use of plant medicines remained unresolved. The aim of this study was to investigate the validity and the scientific basis behind the antimicrobial activity of selected folklore materials and to index their astringent activity using well defined scientific procedures including the newly introduced TAAEq.…”

Purpose:The astringent activity of tannins is due to their ability to bind with proteins which in turn contributes to their antimicrobial properties. The study aimed at determining the correlation between the composite astringent power of folklore plant materials and selected herbal formulations in relation to their antimicrobial activity. Protein precipitating ability (Astringent Power) and Tannic Acid Astringent Equivalents of extracts of the materials were determined. Method: A protein precipitation assay was designed to determine the Tannic Acid Astringent Equivalents of the samples. Antimicrobial activity was determined by agar disc diffusion assay with Escherichia coli and Staphylococcus aureus. Results: Folklore materials and formulations showed strong negative correlation coefficients with Tannic Acid Astringent Equivalent values and antibacterial activities. Values observed for the folklore materials were, S. aureus (r = -0.937) and E. coli (r = -0.825) and for the formulations S.aureus (r = -0.9825) and E.coli (r = -0.8774). A new term 'very tender coconut' was introduced to describe Gobalu (Sinhala). Conclusion:The folklore materials and marketed formulations have a strong correlation between composite astringent activities with their antimicrobial powers. High astringent activity corresponds with high antimicrobial activity justifying their ethnobotanical medicinal applications.
