In order to evaluate the effect of chemical and biological nitrogen on growth and secondary metabolites production of Pimpinella anisum L., a factorial experiment was conducted based on randomized complete block design with three replications. Chemical nitrogen in three levels of 0, 60 and 120 kg/ha and biological nitrogen (nitroxin) in three levels of 0, 3 and 6 L/ha were applied as treatments. Results showed that the effect of chemical nitrogen and nitroxin on fertile ombellete/umble, seed yield, essential oil content and essential oil yield, biologic yield, harvest index seed and harvest index essential oil was significant. Means comparisons showed that the maximum (13.1) and minimum (12.2) number of ombellete/umble were respectively recorded for the treatment with 3 l/ha nitroxin and control treatment (without chemical and biological nitrogen). The highest seed yield (872.8 kg/ha) was obtained from 3 L/ha nitroxin and 60 kg/ha chemical nitrogen while the lowest seed yield (478.3 kg/ha) was obtained from control treatment. According to the results, maximum essential oil yield (115.14 kg/ha) was recorded for the treatment of 3 L/ha nitroxin and 60 kg/ha chemical nitrogen, and the minimum oil yield (55.35 kg/ha) was obtained from control treatment.

In a double blind randomized clinical trial, 66 Holstein cows with a mean age of 4.9±1.55 years, mean weight 548±105 and symptoms of anorexia or loss of appetite were selected. The animals have been divided into two groups. One group, were administered by the mixture of chicory (Cichorium intybus L.) and anise (Pimpinella anisum L.) and another group administrated by the mixture of nux vomica and Gentian (Ruminotoric ®) for 2 days consequently. All animals were closely observed for any clinical improvement such as rate of appetite, frequency and strength of ruminal contractions, after and before the treatment. Results showed that, mixture of chicory and anise affect on rate of appetite, frequency and strength of ruminal contractions significantly (p<0.001). There was no significant difference between Ruminotoric and the mixture of chicory and anise in symptoms of appetite (p>0.05). The rate of healing for chicory mixture and anise group was %77.8. The mixture of chicory and anise which is an herbal preparation appears to be safe, cost effective and promising alternative to conventional drugs for the improvement of anorexia in cows.

Drought stress provokes ROS production in plant cell chloroplasts and subsequently causes lipid membrane peroxidation and damage. Pimpinella anisum L. is one of the aromatic herbal plants which has great export value. The aim of this study was applying exogenous ascorbate in order to control oxidative stress during drought tolerance. Changes of pigment content of leaves, total phenol compounds, malonedialdehyde (MDA) content were measured. In a pot study, drought stress introduced to treatments with 3 replicates based on 3 levels of field capacity (100, 60 and 25%) and ascorbate (1.4 mM) sprayed on them. Chlorophyll content and chlorophyll a/b ratio decreased with increasing in stress levels, while flavonoids and anthocyanins increased. Carotene and xanthophyll increased only in moderate stress level due to drought. Exogenous ascorbate increased chlorophylls and carotenoid content but decreased flavonoid and anthocyanin contents and had great effect on increasing phenol compound in all stress levels. MDA content remained relatively constant, but increased significantly in severe stress levels. Applying exogenous ascorbate led to decreasing metabolite. According to the results exogenous ascorbate could increase the ability of Pimpinella anisum in response to drought stress with different mechanisms and had protective effect against lipid peroxidation due to drought stress.
