Illustration of compound identification procedure in the present work. (a) A screened compound. (b) The resolved chromatogram and mass spectrum of the compound. (c) Candidates in the NIST. (d) With the aid of RI, a candidate was finally accepted and confirmed. “G1,” “G2,” “G3,” and “G4” represent the initial bloom stage, the pre-full bloom stage, the full bloom stage, and the ending of the bloom stage, respectively.
