The ethanol extract of Chinese medicinal herb,Evodia rutaecarpaHort unripe fruits, was found to possess nematocidal activity against the root-knot nematodes,Meloidogyne incognita, during the screening program for new agrochemicals from local wild plants and Chinese medicinal herbs. Bioactivity-guided chromatographic separation of the ethanol extract ofE. rutaecarpaon repeated silica gel columns led to isolate five constituent components (two limonoids, evodol and limonin; three alkaloids, evodiamine, rutaecarpine, and wuchuyuamide I). Evodiamine (LC50=73.55 μg/mL) and rutaecarpine (LC50=120.85 μg/mL) exhibited stronger nematocidal activity againstM. incognitathan the crude ethanol extract ofE. rutaecarpa(LC50=131.54 μg/mL). Wuchuyuamide I, evodol, and limonin also possessed nematocidal activity againstM. incognitawith LC50values of 147.87 μg/mL, 155.02 μg/mL, and 197.37 μg/mL, respectively, but weaker than the crude ethanol extract ofE. rutaecarpa.

Essential oil of chinese medicinal herb,Evodia rutaecarpaunripe fruits was found to possess insecticidal activity against maize weevils,Sitophilus zeamais and red flour beetlesTribolium castaneum. The essential oil ofE. rutaecarpawas obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 38 components of the essential oil were identified. The principal compounds inE. rutaecarpaessential oil wereβ-myrcene (17.7%), (Z)-β-ocimene (14.8%),α-phellandrene (14.7%),γ-terpinene (6.4%), linalool (5.7%) andβ-thujene (5.1%). Bioactivity-guided chromatographic separation of the essential oil on repeated silica gel columns led to isolate three volatile components (β-myrcene,β-ocimene andα-phellandrene) from the essential oil.α-Phellandrene was strongest fumigant againstS. zeamaisadults,T. castaneumadults andT. castaneumlarvae with LC50values of 15.61, 19.78 and 47.96 mg/L air, respectively.β-Myrcene andβ-ocimene also possess fumigant activity against the two species of insects but weaker fumigant activity than the crude essential oil.

During our screening program for agrochemicals from Chinese medicinal herbs and wild plants, the essential oil ofCinnamomum camphoraleaves was found to possess strong fumigant and contact toxicity againstLasioderma serricorneadults with LC50/LD50values of 2.5 mg/L air and 21.25 μg/adult, respectively. The essential oil obtained by hydrodistillation was investigated by GC and GC-MS. The main components of the essential oil were identified to beD-camphor (40.54%), linalool (22.92%), cineole (11.26%), and 3,7,11-trimethyl-3-hydroxy-6,10-dodecadien-1-yl acetate (4.50%). Bioactivity-directed chromatographic separation on repeated silica gel columns led to the isolation ofD-camphor and linalool.D-camphor and linalool showed strong fumigant toxicity (LC50= 2.36 and 18.04 mg/L air, resp.) and contact toxicity (LD50= 13.44 and 12.74 μg/adult, resp.) againstL. serricorne. The results indicate that the essential oil ofC. camphoraand its active compounds had the potential to be developed as natural fumigants and insecticides for control ofL. serricorne.

Essential oil of Chinese medicinal herb,Chenopodium ambrosioidesaerial parts was found to possess nematicidal activity against the root-knot nematodes,Meloidogyne incognita. The essential oil ofC. ambrosioideswas obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 27 components of the essential oil were identified. The principal compounds inC. ambrosioidesessential oil were (Z)-ascaridole (27.27%),ρ-cymene (19.05%), isoascaridole (14.75%),α-pinene (6.33%) andα-terpinene (5.12%). Bioactivity-guided chromatographic separation of the essential oil on repeated silica gel columns led to isolate three volatile components ((Z)-ascaridole,ρ-cymene and isoascaridole) from the essential oil. The essential oil and (Z)-ascaridole exhibited strong nematicidal activity againstM. incognitawith LC50values of 49.55 μg/mL and 32.79 μg/mL, respectively.ρ-Cymene and isoascaridole also possessed nematicidal activity againstM. incognitawith LC50values of 435.89 μg/mL and 1323.51 μg/mL, respectively but weaker than the crude essential oil.

In the present research work the phytochemical and Chromatographic separation of bio active compounds Berberis lycium occurred. Phytochemical investigation of the CH2 Cl2 /CH3 OH (1:1) extract ethanol of root shown the presence of terpenoids, flavonoids, saponins, anthraquinones and alkaloids, steroids and tannins was absent. Chromatographic separation of CH2 Cl2 /CH3 OH (1:1) root ethanol extract yielded methyl 9, 10-dihydro-3, 8-hydroxy-6-methyl-9, 10-dioxoanthracene-2- carboxylate, isolated for the first time from the species of Berberis lycium. With the help of spectroscopic methods (IR, 1 H NMR, 13C NMR, and DEPT-135 and UV-Vis,) Partial characterization of the isolated compound was done.
