Abstract Aims To evaluate the allelopathic effect of Papaver somniferum against the 3 varieties of Zea mays seeds cv. Azam, Pahari and Iqbal. Methods Aqueous extracts were made by soaking the powder of dried leaves of Papaver somniferum. For the aqueous extract treatment, the extract was soaked in distilled water for 24 and 48 hours separately. For mulching treatment, the seeds were sowed in soil and sprinkled powder of leaves. For litter, the petri dishes were grounded with randomly cut pieces of filter paper wetted with extract. For hot water treatment the water was boiled for 5 minutes. The powder was then mixed in boil water. Results Azam got effected in 24h extract in aqueous extract treatment while Pahari in 48h treatment. In mulching all the three varieties got inhibited by extract. Azam showed resistance toward the inhibitory effect of extract in litter experiments. Iqbal was affected in hot water extract. Conclusion It is concluded that the extracts obtained from Papaver somniferum showed inhibitory effects on all the three varieties except few exceptions of maize. The plumule and radical growth got affected the most.

Hot Water Extract

Campanula takesimana Nakai (Campanulaceae; Korean bellflower) is one of the endemic herbs of Korea. The plant has been used as traditional medicines for treating asthma, tonsillitis, and sore throat in Korea. A hot water extract of the leaves of C. takesimana exhibited a significant inhibitory effect on lipopolysaccharide (LPS)-stimulated prostaglandin E2 (PGE2) production. Repetitive chromatographic separation of the hot water extract led to the isolation of three new neolignan glucosides, campanulalignans A–C (1–3), with 15 known compounds (4–18). The structures of new compounds 1–3 were elucidated by analyzing nuclear magnetic resonance (NMR) spectroscopic data, along with high resolution quadrupole time of flight mass (HR-Q-TOF-MS) spectrometric data. Among the isolates, simplidin (7), 5-hydroxyconiferaldehyde (11), icariside F2 (12), benzyl-α-l-arabinopyranosyl-(1″→6′)-β-d-glucopyranoside (13), and kaempferol 3-O-β-d-apiosyl (1→2)-β-d-glucopyranoside (15) were isolated from the Campanulaceae family for the first time. The isolates (1, 2, and 4–18) were assessed for their anti-inflammatory effects on LPS-stimulated PGE2 production on RAW 264.7 cells. 7R,8S-Dihydrodehydrodiconiferyl alcohol (5), 3′,4-O-dimethylcedrusin 9-O-β-glucopyranoside (6), pinoresinol di-O-β-d-glucoside (8), ferulic acid (10), 5-hydroxyconiferaldehyde (11), and quercetin (18) showed significant inhibitory effects on LPS-stimulated PGE2 production.

The inhibitory ability of Fokienia hodginsii heartwood (FHH) extracts on Trametes versicolor (TV) and Gloeophyllum trabeum (GT) as well as the toxic effect of its heartwood extracts on GT were studied. The growth inhibition ability of the samples was analyzed using the growth rate method. The results showed that in the experiment of inhibiting TV, extracts using hot water had little effect, acetone extracts had the best inhibiting effect, and the lowest value of acetone EC50 was 0.409 g/L. The parameter EC50 is the concentration of the corresponding agent that inhibits the growth of 50% fungi. In the antifungal experiment of GT, methanol extract had the best inhibition effect, and the lowest EC50 value was 0.283 g/L. The antifungal effect of five solvent extracts of FHH was good when the concentration was 10% (w/w), and at this time, the mass loss rate of the test pieces was below 11%, all of them were Class I, indicating a strong antifungal level. After observing the samples of GT with SEM, it was found that the structure of methanol extract treatment was more complete and the antiseptic effect was better than that of the hot water extract treatment.

Allelopathic Effect

ABSTRACT: The soil mediated allelopathic effect of Echinochloa colona (L.) Link (jungle rice) was investigated on seed germination and seedling growth of Zea mays L. (maize). The experiment was conducted in the Agronomy farm of the University of Agriculture, Faisalabad, Pakistan. This study investigated the effect of different concentrations (1, 2, 3, 4 and 5% on w/w basis) of soil incorporated E. colona plant residues on emergence and seedling growth of maize and compared them with residue free soil (control). The results revealed the significant increase with soil incorporated E. colona residues in maize seedling growth till 2% E. colona plant residues, and an inhibitory effect was noticed over 2% E. colona plant residues in comparison to the control treatment. There was maximum reduction in emergence percentage, root and shoot lengths, root and shoot dry weights and seedling vigor index of maize seedlings at 5% E. colona plant residues. Quercetin, ferulic acid, sinapic acid, syringic acid, cinnamic acid, m-coumaric acid were identified as water soluble phenolic in water extract of E. colona.

Hot Water Extract

The leaf of Japanese big-leaf magnolia (Magnolia obovataThunb.) has long been used as a natural packaging material for traditional foods in Japan. However, many of the physiological functions of the leaves against oral infection and resultant illness remain unclear. The aim of the present study was to investigate the effects of a hot-water extract of the leaves ofMagnolia obovataon diarrhea induced by rotavirus (RV), a major cause of acute diarrhea. RV strain SA11 was mixed with theM. obovataleaf extract and inoculated orally to neonatal BALB/c mouse pups. Simultaneous inoculation of SA11 with the extract significantly decreased the incidence of diarrhea. In addition, the extract significantly inhibited cytopathic effects and mRNA expression of viral proteins in SA11-infected MA104 cells. Two flavonoid glycosides, quercitrin and rutin, were strongly suggested to be major anti-RV agents in the extract by serial solvent extraction and reversed-phase HPLC-ESI-MS analysis. Our results suggest that the hot-water extract ofM. obovataleaves can be used as a medicine or food additive to prevent and ameliorate RV-induced diarrhea in individuals that may have difficulty in benefitting from the RV vaccines.
