Amomumschmidtii (K.Schum.)Gagnep (syn. A.biflorum
Jack) is the annual plant, that prefer to grow in the
moist atmotphere. A.biflorum Jack has a specific smell,
especially at the rootstock. A.biflorum Jack’s oil was extracted
by steam distillation, and the most extracted plant
compounds were terpene groups. A.biflorum Jack’s oil
was tested by 2,2-Diphenyl-1-picrylhydrazyl radical scavenging
(DPPH), and found the anti-oxidant of 18.29,
15.36, and 7.26 μg/ml in the rainy, winter, and summer
season, respectively (by comparing with standard Trolox).
Therefore, 1% of A.biflorum Jack’s oil was mixed to the
cream for testing the moistness, oiliness, and the distance
between skin creases, which comparing coconut-cream,
cold-cream, and bare-skin at 0, 1, 10, 30, 60, and 120
minutes. The test of moistness, oiliness used the corneometer,
and the sebumeter of the multi-probe adapter system,
respectively. the distance between skin creases were
measured under stereomicroscope using 6.5X magnification.
The t-test and ANOVA were used for analysis. A.biflorum
Jack’s cream significantly increased moisture, and
oily skin at pre and at post 120 minutes (t(44)= -6.4, and
-4.79, p<0.01, respectively). Moreover, A.biflorum Jack’s
cream significantly decreased the distance between skin
creases (t(44)= 2.79, p<0.01). Moisture and oily skin were
significantly different between A.biflorum Jack’s cream,
coconut-cream, cold-cream, and bare-skin (F(3,1076) =
39.51 and65.69, p<0.001). However, The distance between
skin creases was not significantly different between
4 types of testing (F(3,1076) = 5.48, p=0.23). Additionally,
A.biflorum Jack’s was not found the microbacteria,
and the compound in the cream was stablilty, which was
checked by Fourier Transform Infrared Spectroscopy (FTIR).
Finally, A.biflorum Jack’s cream is ready apply for
preventing dry skin in working age adults.
