Other claims from this paper (10)
- Observation l-Quebrachitol, phenylalanine and trans-4-hydroxy-N-methylproline were identified in Croton ehrenbergii by spectroscopic analysis.
- Observation The flavonoids kaempferol, tiliroside and nicotiflorine were identified in Croton ehrenbergii by spectroscopic analysis.
- Observation The flavonoid rutin was identified in Croton ehrenbergii by spectroscopic analysis.
- Intervention effect The methanol and hexane fractions did not inhibit germination and elongation in Lolium perenne.
- Intervention effect l-Quebrachitol showed slightly higher seed germination inhibition in Lolium perenne than in Lactuca sativa.
- Intervention effect Three of the evaluated fractions showed nematicide activity against Meloidogyne incognita J2 larvae at 48 h, compared with carbofuran.
- Intervention effect l-Quebrachitol caused higher mortality of nematodes after 48 h at a lower concentration than carbofuran.
- Observation All fractions had a good mortality percentage against J2 Meloidogyne incognita larvae.
- Observation Some isolated compounds were common within the Croton genus (kaempferol, tiliroside, nicotiflorine, rutin), whereas others (l-quebrachitol, phenylalanine, trans-4-hydroxy-N-methylproline) were not.
- Recommendation The authors recommend that the methanol and hexane fractions and l-quebrachitol could be used as alternative natural herbicides, predominantly against dicotyledon weed seeds.
