Description
Summary:In addition to Aloe vera which is bitter in taste, a non-bitter Aloe is also found in arid part of Rajasthan. This non-bitter Aloe (NBA) is sporadically cultivated as vegetable and for health drink. In spite of its cultivation and various uses, very little information is available about its detailed botanical parameters and chemical characters. This study aims to evaluate the physico-chemical characters of NBA through employing floral morphology, leaf characters and leaf gel and to compare them with those of A. vera . Of eleven floral characters studied, eight characters of NBA were significantly different from that of A. vera . Most visible difference was observed in their reproductive shoots which are highly branched in NBA (5.21 inflorescence/shoot) as compared to A. vera (1.5 inflorescence/shoot). NBA produces less leaf-biomass (−29.32 %) with less leaf-thickness (−31.44 %) but higher leaf length, width, and no. of spine/side by 17.56 %, 21.34 % and 16.11 %, respectively, with significant difference as compared to A. vera . But its polysaccharide content (0.259 %) is at par with that of A. vera . The raw juice from the leaf of NBA has very low aloin content (4.1 ppm) compared to that from A. vera (427.3 ppm) making it a safer health drink compared to the one obtained from A. vera . Thus, NBA raw juice emerged as suitable alternative to A. vera juice for human consumption.
