Abstract :

This study determined the phytochemical constituents of cuberoot (Lonchocarpus cyanescens) indigenous leaves and evaluated the organoleptic attributes and acceptability of 100 per cent cotton faic treated with dye extracted from cuberoot leaves. The study design was quasi experimental and was conducted at the University of Nigeria, Nsukka. The population was 41 panelists comprising 17 Lecturers and 24 Postgraduate students from University of Nigeria, Nsukka. Phytochemical analysis of cuberoot dye was done using Spectrophotometric and gravimetric methods. Organoleptic attributes and acceptability evaluation [OAAE] instrument was used for data collection and data were analyzed with descriptive statistics.Null hypothesis was tested at 0.05 Level of significance using t–test. Findings include; presence of lutein (.007�.0014), tannin (.129�.0014), polyphenol (.0021�.0028), flavonoid (5.16�.014), carotenoid (2.23�.028), per 100g of cuberoot leaves. Seven cuberoot dye organoleptic attributes on cotton faic were identified; five organoleptic attributes were unanimously accepted by both categories of evaluators; There were no significant differences (P>0.05) in the mean rating responses of lecturers and postgraduate students on the acceptability of the organoleptic attributes of the cubeetroot dye on cotton faic in three instances but differences existed in three instances. The null hypothesis was therefore, accepted in three instances and rejected in three instances at 0.05 probability level.
