Summary
Polygonatum odoratum aqueous extraction shows strong ultraviolet absorption, outperforming alcohol extraction. Onion alcohol extract also effectively absorbs medium and long-wave ultraviolet light for UV damage prevention.
Area of Science:
- Phytochemistry and Natural Product Chemistry
- Photoprotection Mechanisms
Context:
- Plants possess natural compounds that can absorb ultraviolet (UV) radiation.
- UV damage poses a significant threat to plant health and cellular integrity.
- Investigating plant extracts for UV-absorbing properties is crucial for developing natural photoprotective agents.
Purpose:
- To evaluate the UV-absorbing capabilities of Polygonatum odoratum and onion extracts.
- To compare the efficacy of aqueous versus alcohol extractions for UV absorption.
- To identify plant-derived agents for preventing UV-induced damage in plants.
Summary:
- Ultraviolet-visible spectrum scanning revealed that Polygonatum odoratum aqueous extracts exhibit strong UV absorption (290-400 nm), with regional variations between Heilongjiang and Hunan varieties.
- While Polygonatum odoratum aqueous extraction generally showed higher absorption than its alcohol counterpart, onion alcohol extract demonstrated significant absorption across the medium and long-wave UV spectrum (290-400 nm).
Impact:
- Identifies Polygonatum odoratum and onion extracts as potential natural UV protectants for plants.
- Provides data for selecting optimal extraction methods (aqueous for Polygonatum odoratum, alcohol for onion) for UV absorption.
- Contributes to the development of eco-friendly strategies to mitigate UV damage in agricultural and horticultural applications.

01:02Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for electronic transitions. As a result...
01:14UV–Vis Spectrometers
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell. Samples for...
01:30UV–Vis Spectrum
When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar absorptivity (ε) or log ε on the y-axis (ordinate)...

01:32UV–Vis Spectroscopy of Conjugated Systems
Organic compounds with conjugated double bonds show strong absorption features in the UV–visible region of the electromagnetic spectrum attributed to π → π* electronic excitations. Generally, a UV–vis absorption spectrum is recorded as a plot of absorbance vs wavelength. The wavelength of maximum absorbance, which manifests as a peak in the absorption spectrum, is denoted as λmax.
One of the factors influencing λmax is the extent of conjugation in the...

01:16UV–Vis Spectroscopy: Molecular Electronic Transitions
In Ultraviolet–Visible (UV–Vis) spectroscopy, the absorption of electromagnetic radiation is used to probe the electronic structure of molecules. This technique provides insights into molecular electronic transitions, particularly the movement of electrons between different molecular orbitals. Radiation is absorbed if the energy of the electromagnetic radiation passing through the molecule is precisely equal to the energy difference between the excited and ground states. During this process,...
