ABSTRACT
Aims: This study aims to determine the regulation of β3 integrin protein in the period of embryo implantation after being induced by oil atsiri of purple nutsedge tubers. Study Design: The study employed a completely randomised design using four concentration levels repeated six times. Place and Duration of Study: Organic Chemistry Laboratory and Zoology Laboratory of Faculty of Mathematics and Natural Sciences University of Lampung, between June 2015 and April 2016. Methodology: This study used mouse as experimental animals with 24 female mouse, then mated with male mouse with a ratio (1 female: 1 male). After the vaginal plug was found in female mouse, then the essential oil of purple nutsedge tubers was induced orally (force-fed) according to the treatment dose. Each 6 female mice were grouped as a control group, and 3 treatment groups, consisting of controls (C) = 0.4 ml aquabides, treatment 1 (T1) = 4.5 mg/40g body weight, treatment 2 (T2) = 45 mg/40g body weight, and treatment 3 (T3) = 135 mg/40g body weight. After the one way Anova test, Ho is rejected, meaning there are significant differences and the analysis is continued with multiple comparison tests, in this case the Least Significant Difference (LSD) test is used. Results: The results shown that the induction of essential oils of purple nutsedge tubers can reduce the level of β3 integrin protein in uterus mouse significantly. Conclusion: It is suggested essential oil of purple nutsedge tubers has potential decrease and can reduce the level of β3 integrin protein in uterus mouse during the period of embryo implantation.
ABSTRACT
OBJECTIVE:To optimize the extraction technology of total volatile oil from Cinnamomum cassia Presl. and Cyper-us rotundus L. in Hegan lipi granules. METHODS:With the extraction rate of total volatile oil as the index,Box-Behnken response surface method was applied to investigate the effects of water amount,soaking time for medicinal materials and extraction time by distillation on the amount of the extracted volatile oil and optimize the extraction technology of total volatile oil from C. cassia Pre-sl. and C. rotundus L. in Hegan lipi granules,and verification tests were conducted. RESULTS:The relevant coefficient of the es-tablished quadratic polynomial regression model of 3 variable factors was 0.970 5. The optimal extraction technology was as follows as 5 times as much as the amount of medicinal materials of water,soaking time of 2.5 h,extraction time of 6.0 h. Verification tests showed the extraction rate of total volatile oil was 1.65%,with a deviation rate lower than 2% compared to the predicted value of 1.67%. CONCLUSIONS:The established model is reliable with good predictability. The optimal technology can be used for the ex-traction of total volatile oil from C. cassia Presl. and C. rotundus L. in Hegan lipi granules.
ABSTRACT
Study on chemical compositions of essential oil of Cyperus rotundus L. extracted from the stem and root of plant Cyperus rotundus L. from Nghe An in October 2003. Results: 49 components were detected by combination of GC and GC/MS, in which 18 had been identified. Monoterpens accounted for high level in essential oil. The main components were -cyperon (14.5%), cyperen (7.8%), caryophylen oxid (6.5%), -selinen (6.3%). Essential oil level was 0.2% for fresh samples. Essential oil had soil-yellow color and specific slight perfume
