Area of Science:

  • Biomaterials Science
  • Drug Delivery Systems
  • Natural Product Chemistry

Background:

  • Pine pollen possesses a unique multicavity structure with hollow air sacs, ideal for compound loading.
  • A natural lipidic layer on pine pollen limits its permeability and water uptake.
  • Developing effective natural drug delivery systems requires overcoming these limitations.

Purpose of the Study:

  • To investigate compound loading within pine pollen.
  • To develop all-natural formulations for targeted intestinal delivery using pine pollen.

Main Methods:

  • Pine pollen was defatted to remove the lipidic layer, enhancing surface wetting and water uptake.
  • Optimization of loading parameters facilitated the encapsulation of bovine serum albumin (BSA) within the pollen's sexine structure.
  • Formulations were prepared using defatted pine pollen, xanthan gum, or sodium alginate for oral delivery.

Main Results:

  • Defatting pine pollen significantly improved its permeability and water absorption.
  • Effective loading of BSA into the pollen's outer shell was achieved.
  • All-natural oral formulations for intestinal delivery were successfully developed.

Conclusions:

  • Pine pollen is a promising, cost-effective natural microencapsulant due to its cargo capacity and ease of loading.
  • Modified pine pollen can be utilized for developing targeted intestinal drug delivery systems.
  • Its abundant availability and historical use support its potential in various applications.
