ABSTRACT: The herbal medicines have been largely used since form several thousands of years in all developing and developed countries in the primary health care of community and society. Flavonoids are the class of polyphenolic secondary metabolites, which are mainly found in plants. Apigenin is a flavonoid which shows several pharmacological activities and used effectively for the management and treatment of several diseases and disorders. Many herbal medicines and their preparation containing Apigenin are available in market and hence Quality Control and standardization of Apigenin is important and essential in ayurvedic industries. The scientific research articles published on analytical development and validation of Apigenin and its estimation in its extract, isolated form and other herbal or polyherbal formulations were reviewed. We have mainly focused on chromatographic and spectroscopic techniques for qualitative and quantitative analysis of Apigenin and presented in this review work. We conclude here that the spectroscopic and chromatographic methods play significant role in the quality control and standardization of Apigenin in herbal medicines.
Keywords: Apigenin, Flavonoid, Validation, Quality Control, Herbal Medicines
INTRODUCTION: Herbal medicinal plants have been recognised for millennia as a rich source of therapeutic agent for prevention of diseases and disorders and are highly respected all over the world. Nature has bestowed upon our land an abundance of herbal medicines in the form of plants. Among ancient civilisation, India has been known to be rich storehouse of herbal medicinal plants, treatment with herbal medicinal plants is considered as safe because there is no or least side effects.
More than three- quarters of the world’s population depends mainly on herbal medicinal plants for their health care needs. Plant-based medications are becoming more popular in both developed and developing countries as people realise that natural products have fewer side effects, non-toxic and readily available 1. With the increasing use of herbal goods, a wide range of phytomedines, herbal medicine and their formulation are widely available in the market all around the world.
Increase in demand of herbal medicine has faith that all natural products are safe and effective. However, there are still some concerns are associated with herbal medicine concerning its pharmacognosy, standardization and Quality control of drugs and it has become a public health concern 2. The herbal drug used in developing countries of the world lacks official quality control standards, there is no way to ensure that the quality of different batches is consistent. Quality control includes safety of herbal drugs, efficacy and toxicity in herbals and their interactions these quality control parameters need to be tested before the finished product is manufactured, marketed, and ingested by patients. Standardization of herbal formulation is required for the evaluation of high-quality medications. There are variety of tools available that can be used to both qualitative and quantitative measures of herbal medicine. To isolate, identify the phytoconstituents responsible for the medicinal potential of herbs/plants, sophisticated analytical techniques are continually being developed und upgraded. Mainly the spectroscopic and chromatographic methods play major role in quality control and standardization of herbal formulation 3.
Flavonoids are the class of polyphenolic secondary metabolites. They are the important class of natural products, widely observed in flowers, plants, tea, grains, bark, stem, roots, vegetables, fruits and wine. Flavonoids, being the main active ingredient, provide a variety of health-promoting pharmacological effects such as anti-allergic, anti-oxidant, anti-inflammatory, anti-mutagenic and anti-carcinogenic effects. Apigenin is a flavonoid that has been used as a traditional herbal medicine because of its anti-oxidant, anti-inflammatory, antibacterial and antiviral properties. Apigenin is also known for its anticancer properties, which can be used to treat a variety of cancers. It has great demand due to its safety and effectiveness 4.
Apigenin is a flavonoid, widely found in a variety of fruits, vegetables and plants. Vegetables such as parsley, oranges, onions, maize, tea, rice, wheat sprouts chamomile, wheat sprouts. Parsley and peppers are two most common sources of flavones containing Apigenin. Apigenin is a polyphenolic metabolite, chemically known as 4ˈ,5,7, -trihydroxy flavone 5.
MATERIALS AND METHODS: Numerous herbal medicines and their preparation containing Apigenin are available in market.

They have used methanol as solvent system. Calibration curve was constructed using concentration range of 2-12µg/ ml at 335nm and 2-14µg/ml at 268nm. The reported method was not economical because they have used high percentage organic phase 6. Rathode P. et. al., have reported validation of UV- method for quantification of Apigenin in leaves extract of Parsley. In this method maximum wavelength of Apigenin was observed at 208nm. They have used methanol as solvent system in ratio of 50:50 % v/v. Calibration curve was constructed using concentration range of 0.5 to 12µg/ml 7.

In this method maximum absorbance wavelength of Apigenin was observed at 267nm. They have used methanol as solvent. The detector response for apigenin was linear in the sure concentration range of 2µg/ml-10µg/ml with relation coefficient of 0.9995. This reported method was found to be specific, selective linear, precise, rugged, reproducible for estimation of apigenin with %RSD values less than 2 8. The detailed summery of spectroscopic standardization of Apigenin is presented in Table 1.

CONCLUSION: Quality control analysis is major and essential step in the manufacturing of herbal formulations as the quality of product affects the safety and efficacy of medicinal products. The quality control parameters need to be tested before the finished product is manufactured, marketed, and ingested by patients. Flavonoids are the class of polyphenolic secondary metabolites, which are derived from plants. Apigenin is a flavonoid that has a variety of medicinal properties. Many herbal medicines containing Apigenin are available in market and hence quality analysis is essential. The spectroscopic and chromatographic methods play major role in the quality control and standardization of Apigenin in its extract, isolated from or any other herbal or polyherbal formulation.
