Pectin is plant based, and consists of a complex set of polysaccharides. The amount, structure and chemical composition of pectin differs among plants, within a plant over time, and in various parts of a plant.

Healing Properties

  • Antiproliferation
    • Citrus Pectin fragments such as, rhamnogalacturonan, exhibit high anti-proliferation activities against human colon adenocarcinoma (colon cancer) cells.[1]
  • Prebiotic: Promotes increase of beneficial bacteria in gut microbiota.
  • Reduces blood cholesterol levels.

Disease / Symptom Treatment

  • Cancer
    • Colon Adenocarcinoma (colon cancer): Citrus Pectin fragments such as, rhamnogalacturonan, inhibit cancer cell proliferation.[1]
  • Hypercholesterolemia: Helps reduce high levels of cholesterol in the blood.

    Abstract: This study was to identify active pectin fragments of high in vitro anti-proliferation activities against human colon adenocarcinoma Caco-2 cells, using various pectin fragment preparations dominant with rhamnogalacturonan I (RG-I), rhamnogalacturonan II (RG-II), and galacturonic acid oligomers (GAOS). The samples were prepared from citrus high and low methoxy pectins (HPE and LPE) by endo-α-D-(1,4)-polygalacturonase action coupling with a green process as ultrafiltration (membrane molecular weight cut off > 10k, 1k-10k, and < 1k, giving fragment preparations I, II, and III, respectively). It is indicated that, in the fragment preparations HPE-I, II, and III, the molecular fractions HPE-F1 (RG-I), HPE-F2 (RG-II), and HPE-F3 (GAOS) showed an averaged Mw = 26.7k, 3.4k, and 0.3k, respectively, notably higher than their LPE counterparts. All fragment preparations exhibited concentration-dependent, inhibition effects on Caco-2 cells, where HPE-II (RG-II-domain) revealed an interesting inhibition effect, significantly higher than those did HPE-I (RG-I domain) and HPE-III (GAOS). The HPE-F2 (RG-II) was elucidated and found of IR = 88% at 1.0 mg/mL and half-inhibition concentration (IC50) = 0.12 mg/mL, doubling the effect of HPE-F1 (RG-I) (IR = 45% at 1.0 mg/mL). Conclusively, citrus RG-II fragment showed a promisingly high anti-Caco-2 activity, significantly higher than did RG-I and GAOS, possibly attributed to its special branched structure and low molecular size.
