Comparative trial of moisturizer containing spent grain wax, Butyrospermum parkii extract, Argania spinosa kernel oil vs. 1% hydrocortisone cream in the treatment of childhood atopic dermatitis.
Abstract
OBJECTIVE:
To compare an efficacy of a moisturizer containing spent grain wax, Butyrospermum parkii extract, Argania spinosa kernel oil (S) with 1% hydrocortisone cream (HC) for the treatment of mild to moderate atopic dermatitis.
MATERIAL AND METHOD:
Twenty-nine patients, age between 2 and 15 years old with mild to moderate atopic dermatitis were enrolled The body was randomly divided to left and right side. One side was applied with S cream and the other side was applied with HC cream twice daily for four weeks. Observation of recurrence rate after remission was recorded. Clinical outcomes were analyzed by using the scoring ofAtopic Dermatitis (SCORAD) score. Statistical analysis was done by using descriptive statistics, pair t-test, one-way repeated ANOVA, and McNemar's test.
RESULTS:
It was demonstrated that both agents had improvement of SCORAD score after two weeks, with statistically significant difference (p< 0. 001). At fourth week, both agents had improvement of SCORAD score without being statistically significant different (p>0.05). Although the S cream side had higher remission rate than the HC cream side, there was no statistically significant difference (p> 0. 05).
CONCLUSION:
S cream was as effective as HC cream in the treatment and maintenance period of mild to moderate childhood atopic dermatitis.

Abstract
Three new triterpenoid saponins, elucidated as 3-O-β-D-glucopyranosyloleanolic acid 28-O-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranoside (parkioside A, 1), 3-O-[β-D-apifuranosyl-(1→3)-β-D-glucopyranosyl]oleanolic acid 28-O-[β-D-apifuranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-[α-L-rhamnopyranosyl-(1→3)]-α-L-rhamnopyranosyl-(1→2)β-D-xylopyranoside (parkioside B, 2) and 3-O-β-D-glucuronopyranosyl-16α-hydroxyprotobassic acid 28-O-α-L-rhamnopyranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranoside (parkioside C, 3), were isolated from the n-BuOH extract of the root bark of Butyrospermum parkii, along with the known 3-O-β-D-glucopyranosyloleanolic acid (androseptoside A). The structures of the isolated compounds were established on the basis of chemical and spectroscopic methods, mainly 1D and 2D NMR data and mass spectrometry. The new compounds were tested for both radical scavenging and cytotoxic activities. Compound 2 showed cytotoxic activity against A375 and T98G cell lines, with IC(50) values of 2.74 and 2.93 μM, respectively. Furthermore, it showed an antioxidant activity comparable to that of Trolox or butylated hydroxytoluene (BHT), used as controls, against 2,2-diphenyl-1-picryl hydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), oxygen and nitric oxide radicals.
