“…While evaluating antimicrobial potential, Zanthoxylum EO completely checked the growth of A. alternata from a concentration of 0.5-4.5 µl ml −1 . Our findings are in concordance with the EO of Z. armatum used to inhibit mycelial growth of Bipolaris sorokiniana (Manandhar and Tiwari, 2005). From the present study, eucalyptol emerged as a major component of the EO of Z. armatum; it may have played role in retarding the growth of the pathogen, A. alternata-induced tomato fruit rot.…”

Alternaria fruit rot is a major disease caused by Alternaria alternata (Fr.) Keissl., a prolific fungal pathogen. Among post-harvest diseases of tomato, fruit rot induced by A. alternata is the most damaging. Antifungal agents are widely used to control post-harvest management of tomato fruits. However, negative impacts of fungicidal residues in edible fruits and vegetables on human health cannot be over ruled. Eco-friendly ways of controlling Alternaria rot in tomato fruits offer a novel way of tomato rot management. The current study proposes an alternate method in controlling tomato fruit rots through Zanthoxylum armatum DC essential oil (EO) application. Gas chromatography-mass spectrometry profiling showed eucalyptol and sabinene as major components of Z. armatum EO. Furthermore, EO applied (0.5–4.5 μl/ml) showed significant inhibition of A. alternata growth (p > 0.05) at 4.5 μl concentration tested. Lipid peroxidation assays revealed significant reduction in membrane damage in tomato fruits treated by EO compared to alone inoculated fruits with A. alternata. Elevated activities of superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase coupled with enhanced antioxidants such as ascorbic acid, glutathione, proline, and total phenols in EO-treated fruits may be linked with better fruit rot management than control fruits inoculated with A. alternata-induced rot alone. Mycelia and spore production was dramatically reduced in EO applied tomato fruits over A. alternata alone in tomato fruits (p > 0.05). Interestingly, free radical scavenging activities of EO applied tomato fruits showed significant improvement compared to only pathogen-inoculated tomato fruits. Findings propose practical utility of Z. armatum EO as a plant-based antifungal for post-harvest management of Alternaria rot in tomato fruits.

“…Ethanolic extracts of the bark of Zanthoxylum fagara, Zanthoxylum elephantiasis and Zanthoxylum martinicense showed antifungal activity [44], as well as ether, chloroform and methanol extracts of Zanthoxylum budrunga bark [45]. The Zanthoxylum armatum essential oil has been shown to inhibit the mycelial growth of the fungus Bipolaris sorokiniana [46]. Biological activity against fungi has been reported also in the bark of Zanthoxylum usambarense [47] and Zanthoxylum americanum [9].…”

This study aimed to evaluate the in vitro activity of Zanthoxylum rhoifolium bark (Zr-b) extracts against pathogenic aquatic oomycete/fungal isolates that cause different diseases in native European crayfish resulting in an elevated mortality rate and severe economic repercussions. n-hexane, chloroform, chloroform-methanol (9:1) and methanol extracts of Zr-b were used to evaluate the antifungal activity against the strain UEF88662 of Aphanomyces astaci (oomycete) and the strain SMM2 of Fusarium avenaceum (fungus). The anti-oomycete and antifungal activity was quantitatively evaluated by growth, survival and sporulation microbiological assays. The extracts tested demonstrated a dose-dependent inhibitory effect on oomycete and fungal growth and survival, as well as on the production of oomycete and fungal spores. This work presents alternatives for the treatment and prevention of the spreading of Aphanomyces astaci and Fusarium avenaceum, the etiological agents of the diseases crayfish plague and brown spot disease, respectively. The antifungal properties of Zanthoxylum rhoifolium bark extracts warrant further research on their use in the prevention and treatment of both oomycete and fungal diseases. The antifungal properties of Zanthoxylum rhoifolium bark extracts, shown in vitro, indicate the possibility of their use in new therapeutic and prophylactic strategies, providing perspectives for the design of in vivo studies.

Background: The study on drying and its social acceptance has increased rapidly. Among different drying techniques, shade drying is one of the most feasible methods to keep intact from the decay of the main active components of the plant materials. Shade drying is an ancient drying method that increases durability, major constituents and activity of the plant material. Aims: Research was conducted to examine the drying potential of aromatic leaves oil of Zanthoxylum armatum DC. Methods: The fresh plant material was collected from Lohaghat, Champawat district of Uttarakhand and hydrodistilled before and after shade drying to assess the changes in the quality of volatile constituents by GC and GC-MS techniques. A two-tailed paired t-test was executed to assess the difference between drying treatments using MS-Excel. Results: The major components in the fresh oil were 2-undecane, linalool, (E)-β-ocimene, α-pinene and β-phellandrene. In the oil from dried material, the three predominant compounds were noted. A significant increase was observed in the percentage of β-phellandrene, undecanal and myrcene after shade drying (p<0.01). Five components absent in the fresh plant material appeared and one disappeared during the drying process. Conclusion: Shade drying significantly influenced the essential oil composition of Z. armatum.
