¹H NMR Signal Integration: Overview

4.0K
The intensity of a signal, which can be represented by the area under the peak, depends on the number of protons contributing to that signal. The area under each peak is shown as a vertical line called an integral, with the integral value listed under it, as seen in the proton NMR spectrum of benzyl acetate. Each integral value is divided by the smallest integral value to obtain the ratio of the number of protons producing each signal. The ratio reveals the relative number of protons and not...

    Background:

    • Paeonia Radix Alba (white peony root) is a vital herb in Traditional Chinese Medicine.
    • Processing methods significantly impact the quality and active compound content of Paeonia Radix Alba.
    • Optimizing processing techniques is crucial for maximizing therapeutic efficacy.

    Purpose of the Study:

    • To investigate novel origin pre-treating and processing integration techniques for Paeonia Radix Alba.
    • To compare the efficacy of new techniques against traditional processing methods.
    • To determine the optimal conditions for preserving active ingredients like peoniflorin.

    Main Methods:

    • Employed various processing integration techniques for Paeonia Radix Alba.
    • Compared new methods with traditional processing techniques.
    • Assessed drying rate, aqueous extracts, and peoniflorin content.

    Main Results:

    • Half-dry slices baked at 100°C for 20 minutes showed the highest peoniflorin and aqueous extract content.
    • Steaming at 100°C for 10 minutes also resulted in high peoniflorin content.
    • Conventional methods and sulfur-fumigation yielded the lowest aqueous extract content.

    Conclusions:

    • Novel origin processing integration techniques for Paeonia Radix Alba are superior to conventional methods.
    • These advanced techniques result in significantly less loss of active ingredients.
