Figure 2

Chromatograms obtained using HPLC-MS of the control sap, Hm-1, Hs-1, and Hs-2 of the bark decoctions Hm-sb1, Hs-sb1, and Hs-sb2, and of the commercial samples Js-1 to Js-6. The samples Hm-1 and Hm-sb1 belong to H. martiana and Hs-1, Hs-2, Hs-sb1, and Hs-sb2 to H. stigonocarpa. The main peaks of the sap and stem bark are also shown in the chromatogram. Table 2 shows detailed information about the peaks.
