Embodiment

[0015] In March 2008, the inventor cut the tender rhizome of galanga into small sections of about 15 cm in Xiaoguwei Island, Panyu District, Guangzhou City in March 2008, planted it in the soil according to the upper and lower positions during growth, and cultivated it according to conventional cultivation methods.

[0016] Pre-harvest treatment was carried out in October 2011. The galanga plants were randomly divided into 4 groups: control group, experimental group 1, experimental group 2 and experimental group 3, with 10 plants in each group.

[0017] The control group was sprayed with water on the galanga plants before harvesting, once every 3 days, and sprayed 3 times in total.

Abstract

The invention discloses a method for increasing content of eucalyptol in galangal. The method specifically comprises the following steps: before the galangal is harvested, spraying salicylic acid solution to a galangal plant and then harvesting the galangal on time. Through the adoption of the method disclosed by the invention, the content of the eucalyptol in the galangal can be effectively increased; moreover, the method for increasing the content of the eucalyptol in the galangal, disclosed by the invention, has the advantages of low cost, simplicity in operation and convenience for herbalist to master the content and is suitable for producing galangal volatile oil and eucalyptol components on a large scale.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a method for increasing the content of eucalyptol in galangal. Background technique [0002] Galangal ( Alpinia officinarum Hance) is a perennial medicinal plant mainly cultivated in Guangdong, Guangxi, Hainan and other places. Galangal rhizome is spicy and aromatic, and its volatile oil is mainly composed of eucalyptol (accounting for 50%~72.7%), which has anti-inflammatory and analgesic properties, anti-oxidation, anti-ulcer, anti-thrombosis, anti-fungal, anti-vomiting and anti-diarrheal, insect repellent, etc. Active, widely used in medicine, spices, food, fruit and vegetable preservation and other fields. Due to the long production cycle of galangal (3 to 5 years), there are periodic fluctuations in artificial cultivation area and market supply, and the content of volatile oil and eucalyptol in rhizomes also varies due to cultivation management, variety, and cli...
