This study was conducted to determine the growth characteristics, and the effect of plant growth regulators on the sprouting and growth of purple nutsedge(Cyperus rotundus L.) in order to establish effective control system in lawn ground. The flowering of purple nutsedge was initiated 30 days after transplanting regardless of the transplanting time. Low temperature less than $10^{\circ}C$ after flowering was required for tuber formation, showing that the tuberization was related to air temperature. Shoot number and dry weight of underground portion of purple nutsedge was slightly affected by plant growth regulators such as benzylamino purine, abscisic acid, brassinosteroid and jasmonate. Imazaquin applied at 1, 2 and 3 weeks after transplanting induced multi-shooting and inhibited shoot growth indicating that the herbicide played a role as plant growth regulator at a concentration of 30 and 60g ai/10a. The greatest inhibition of purple nutsedge was obtained by pyrazosulfuron-ethyl as applied 1 weeks after transplanting, showing almost 100% control of purple nutsedge. Tuber of purple nutsedge composed of 61.83% of moisture, 31.60% of carbohydrates, 4.03% of crude protein, 1.57% of crude fat and 0.97% of crude ash.

Cyperus rotundus has been grown for a long time in korea to be used as medicinal crop. This study was conducted to survey the production status and economic analysis in chief producing area of Cyperus rotundus in Koryong, Korea. The Koryong area where was the major production area of Cyperus rotundus was composed of 0.6hectare cultivation size per farm household and the processes like cultivation, processing, shipping were formed unitedly. The most general management type was labor-extensive one which use the Nakdong river basin or idle land effectively. The cultivation area have been decreased gradually because the price was very low so that the income per hectare was just 3,880 thousand won and productivity per hectare was just 6,280kg. Thus, production condition was very inferior, it needs some self-help to encourage the production because it has some possibility as only regional special product.

In this study, Cyperus rotundus (C. rotundus) was fractionated into ethyl acetate to identify α-cyperone, a representative indicator, and its ethyl acetate fraction were evaluated to confirm the possibilityas a functional cosmetic ingredient. As a result of HPLC analysis, it was confirmed that the content of α-cyperone was 5.243%. In order to verify the inflammatory relief effect of the ethyl acetate fraction from C. rotundus (EAFC) and α-cyperone, it was confirmed that nitric oxide (NO) production inhibitory ability in RAW 264.7 macrophages induced an inflammatory reaction with lipopolysaccharide (LPS). Real-time qPCR analysis confirmed inhibition of mRNA expression level of inflammatory factors, IL-1β, IL-6, TNF-α, COX-2 and iNOS. As a results of conducting a clinical study using a simple cosmetic formulation containing EAFC, it was confirmed that the skin irritation stimulated by sodium lauryl sulfate (SLS) was calming and relieving itching. Through these results, it is believed that the C. rotundus can be used as a natural cosmetic ingredient that has the effect of inhibiting inflammation and relieving itching.
