Dari beberapa senyawa diatas telah dilakukan uji fitotoksik, hasil uji terhadap lettuce (Lectuca sativa L.) memperlihatkan senyawa (11), (12), dan (18) dapat menghambat perpanjangan akar masing-masing pada (IC50 = 47 mg/ml), (IC50 = 96 mg/ml), and (IC50 = 242 mg/ml). Selain itu pada konsentrasi 250 mg/ml senyawa (11) dapat membunuh perkecambahan biji (Lectuca sativa L.) (Shao et al., 2005). Sementara uji alelophatic senyawa (11), (12), dan (13) terhadap perkecambahan biji (Brassica parachinensis) menunjukkan nilai IC50 masing-masing 0,04; 0,05; and 1,21 mM (Huang et al., 2009).

From some of the above compounds has been carried out, the results of the test fitotoksik test of lettuce (Lectuca sativa l.) showed the compound (11), (12) and (18) may inhibit the extension of the root of each on (IC50 = 47 mg/ml), (IC50 = 96 mg/ml), and (IC50 = 242 mg/ml). Additionally, on the concentration of 250 mg/ml (11) compounds can kill the seed germination (Lectuca sativa l.) (Shao et al., 2005). While the test of alelophatic compounds (11), (12) and (13) of germination the seeds (Brassica parachinensis) showing their respective IC50 values of 0.04; 0.05; and 1.21 mM (Huang et al., 2009).

From some of the above compounds have phytotoxic test, the test results of the lettuce (L. sativa Lectuca) shows the compound (11), (12), and (18) can inhibit root extension respectively in (IC50 = 47 mg / ml), (IC50 = 96 mg / ml), and (IC50 = 242 mg / ml). In addition, at a concentration of 250 mg / ml of compound (11) can kill the seed germination (Lectuca sativa L.) (Shao et al., 2005). While alelophatic test compound (11), (12), and (13) on seed germination (Brassica parachinensis) shows the IC50 value of 0.04 each; 0.05; and 1.21 mM (Huang et al., 2009).
