Descriminant analysis of flowers, leaves, stems of combretum indicum varr.M and Varr.B with UV-vis spectrophotometric chemometric method [PDF]

E3S Web of Conferences, 2023
Combertum indicum has two varieties, namely varr.M and Varr.B., so to maintain the truth of the sample it is necessary to discriminate. The way to distinguish these two varieties can use the UV-vis spectrophotometric approach.
