Effects of Humic Acid Treatments of Yield, Morphological Characteristics and Essential Oil Components of Coriander (Coriandrum sativum L.)

Coriandrum sativum L. belongs to the Apiaceae family, which is cultivated in Dong Nai province, in this paper its seed oil of was studied. The essential oil was extracted by hydrodistillation. We used two methods for activating of hydrodistillation: conventional heating and microwave irradiating. Its physical and chemical indexes were measured. The chemical composition of this oil was identified by GC/MS and quantified by GC/FID. Linalool (75.51-77.21 %), and geranyl acetate (15.64-12.79 %) were the main constituents of the oil which were obtained in 0,32-0.39 % yield. The biological activity of this oil was reported.

Background: Neuropathic pain is one of the contributors to the global burdens of illness. At present many patients do not achieve satisfactory pain relief even with synthetic pain-killers. Taking this into consideration, it is necessary to search for natural product-derived alternative treatment with confirmed safety and efficacy. Ageratum conyzoides L is a plant often used as analgesic in Indonesia, however, anti-neuropathic pain activity of this plant is still unknown. Objective: To determine the anti-neuropathic pain activity of the essential oil and non-essential oil component (distillation residue) of A. conyzoides L. Methods: We conducted separation of the essential oil component from other secondary metabolites through steam distillation. Both components were tested for anti-neuropathic pain activity using chronic constriction injury animal models with thermal hyperalgesia and allodynia tests. The animals were divided into 7 test groups namely normal, sham, negative, positive (pregabalin at 0.195 mg/20 g BW of mice), essential oil component (100 mg/kg BW), and non-essential oil component (100 mg/kg BW). Naloxone was tested against the most potent anti-neuropathic pain component (essential oil or nonessential oil) to investigate the involvement of opioid receptor. Results: The GC-MS of the essential oil component indicated the presence of 60 compounds. Meanwhile, non-essential oil components contained alkaloid, flavonoid, polyphenol, quinone, steroid, and triterpenoid. This non-essential oil component contained a total flavonoid equivalent to 248.89 ppm quercetin. The anti-neuropathic pain activity test showed significantly higher activity of the essential oil component compared to the non-essential oil component and negative groups (p<0.05). Furthermore, the essential oil component showed equal activity to pregabalin (p>0.05). However, this activity was abolished by naloxone, indicating the involvement of opioid receptor in the action of the essential oil component. Conclusion: The essential oil component of A. conyzoides L is a potential novel substance for use as anti-neuropathic pain.

Environmental contamination and the excessive use of inorganic fertilizers resulting in stagnant yields of field crops which necessitate the utilization of combined fertilization approach under changing climatic conditions. Current study was aimed to clarify the influence of several fertilizer sources (chemical, organic, organomineral fertilizers) on yield and quality of coriander (Coriandrum sativum L.). The results revealed that the fertilizer sources significantly affected the yield of coriander cultivars. The absence of “Year x Variety x Fertilizer Type” interactions for any of the noted parameters signaled that the detected “Variety x Fertilizer Type” interactions were constant regardless of the year factor. The recorded values of traits according to fertilizer sources different for the plant height from 61.85 to 69.67 cm, number of branches from 5.98 to 7.71 (piece/plant), number of umbels per the main umbel from 5.62 to 7.18 pieces, seed yield from 1.06 to 1.66 t/ha, the biological yield from 4.29 to 5.70 t ha−1, harvest index from 25.29 to 29.41%, essential oil ratio from 0.29 to 0.33%, and essential oil yield from 3.1 to 5.6 L ha−1. Erbaa variety was observed to be superior over the rest of the varieties producing the maximum values of 6.5 L ha−1 of essential oil, 0.36% essential oil content, 30.9% harvest index, 1.81 t/ha seed yield, and 5.9 t ha−1 biological yield with the treatment of chemical fertilizers.
