The ethanolic extract of date palm pollen significantly inhibited granuloma induced by Schistosoma mansoni soluble egg antigen in vitro

Dried pollen grains of three date palm (male) cultivars grown in Oman were stored either in a freezer (-18°C), a refrigerator (4 to 5°C), or at room temperature (23 to 25°C) for 6 or 12 months. The three cultivars include Khori, Medjahdil, and Bahlani. Germination percentage was determined after 6 hours incubation in aerated and non- aerated liquid media. The results showed that date palm pollen was better adapted to refrigerator storage than freezing for all three cultivars, while room temperature storage significantly reduced pollen germination. Aeration was found to enhance germination of refrigerator- and freezer-stored pollen, but decreased that of pollen stored at room temperature for 6 months. The results also indicated that refrigeration might have caused the inactivation of pollen germination. The latter could either be overcome by aeration or reversed if pollen is refrigerated for a longer period. Room temperature storage directly reduced viability and did not induce temporary inactivation of pollen.

Etoac Fraction

Chemical investigation of the EtOAc fraction (EF) obtained from the ethanolic extract of Zanthoxylum naranjillo (Rutaceae) leaves (EE) by preparative HPLC resulted in the isolation of protocatechuic acid (1), gallic acid (2), p-hydroxybenzoic acid (3), and 5-Ocaffeoylshikimic acid (4). This is the fi rst time that the presence of compounds 1 - 4 in Z. naranjillo has been reported. Compounds 1 - 4, the EE, and EF were tested in vitro against Schistosoma mansoni adult worms. The results showed that the S. mansoni daily egg production decreased by 29.8%, 13.5%, 28.4%, 17.7%, 16.3%, and 6.4%, respectively. Compounds 1 and 3 were also able to separate adult worm pairs into male and female. This activity may be correlated with the reduction in egg production, since 1 and 3 showed better inhibitory properties compared with 2 and 4.
